Animals That Start With B: Names, Types, and Verified Facts
Animals that start with B include the baboon, badger, bald eagle, barracuda, bat, bear, beaver, bee, bison, black rhinoceros, blue whale, bobcat, bonobo, box jellyfish, bumblebee, and butterfly. The letter B covers animals from nearly every major branch of animal life, including mammals, birds, reptiles, amphibians, fish, insects, arachnids, mollusks, crustaceans, and cnidarians.
Some B animal names identify a particular species, while others refer to much broader groups. The blue whale, for example, is one species, Balaenoptera musculus. Names such as bear, bat, bee, beetle, butterfly, and buffalo encompass many different species.
This distinction explains why there is no meaningful scientific total for “animals that start with B.” Lists also become much longer when they include domestic breeds, geographic modifiers such as Bengal tiger and Bornean orangutan, extinct animals, or multiple common names for the same species.
This guide therefore focuses on recognizable and scientifically useful B animal names while explaining the animals, classifications, habitats, adaptations, and conservation stories behind them.

This is a representative list rather than a claim that only 50 B animals exist. Hundreds of additional common names can be produced when individual species, breeds, subspecies, regional names, and extinct animals are counted separately.
Mammals That Start With B
Some of the best-known B animals are mammals. This group includes primates, rodents, carnivores, hoofed mammals, marsupials, rhinoceroses, and the largest animal known to exist.
Baboon
Baboon is the common name for a group of large Old World monkeys native to Africa and parts of the Arabian Peninsula.
Baboons are highly social and generally live in groups in which relationships, rank, cooperation, conflict, and communication influence daily life. Their diet can include grasses, fruit, seeds, roots, insects, and animal prey, depending on species and habitat.
The name “baboon” should therefore be treated as a group name rather than as a single species. Several closely related species carry the name, including olive, yellow, chacma, Guinea, and hamadryas baboons.
Bactrian Camel
The Bactrian camel is immediately recognizable by its two humps. It is associated with the dry and seasonally harsh landscapes of Central Asia.
There is an important difference between domestic Bactrian camels and the wild camel, which represents a distinct wild lineage. Alphabetical animal lists sometimes combine these animals even though their biological and conservation histories are different.
Camels store fat in their humps rather than water. That stored energy is one of several adaptations that help them cope with environments where food and water availability can fluctuate sharply.
Badger
Badger is another group name. Several stocky, digging mammals across different genera are commonly called badgers.
Powerful forelimbs and long claws make many badgers effective excavators. They use burrows for shelter and may feed on everything from insects and worms to small vertebrates, roots, fruit, and other plant material.
The American badger, European badger, honey badger, and Asian badger species are not simply regional versions of one animal. Their taxonomy, behavior, and ecology differ.
Bat
Bats are mammals in the order Chiroptera, and they are the only mammals capable of true powered flight.
Their diversity is much greater than the stereotypical image of an insect-eating cave bat suggests. Different species consume insects, fruit, nectar, fish, small vertebrates, and other foods. Some pollinate flowers or disperse seeds, while insect-eating bats can influence insect populations.
The Smithsonian notes that roughly 1,440 bat species are known and that bats occur on every continent except Antarctica. The institution also highlights their roles in pollination, seed dispersal, and pest control.
Only three living bat species feed exclusively on blood, so the familiar vampire-bat image represents a tiny fraction of global bat diversity.
Bear
The word bear refers to mammals in the family Ursidae. Living bears occupy habitats ranging from Arctic sea ice and North American forests to mountainous regions and tropical Asian forests.
Their diets vary considerably. Polar bears are strongly carnivorous, while other bears may consume combinations of vegetation, insects, fish, mammals, carrion, nuts, berries, and other foods.
Several more specific B names belong within this broader group, including black bear, brown bear, and some regional bear names.
Beaver
The beaver is a semiaquatic rodent famous for altering streams by constructing dams.
That engineering can slow moving water and create ponds and wetlands that provide habitat for other organisms. The U.S. National Park Service therefore describes beavers as ecosystem engineers. Their continuously growing incisors also allow them to cut and process woody vegetation.
The North American beaver is Castor canadensis, while Eurasia has another living species, Castor fiber. The common name “beaver” can consequently describe more than one species.
Bighorn Sheep
The bighorn sheep is a North American wild sheep named for the massive curved horns carried by mature males.
Rocky slopes and mountainous terrain provide important escape habitat from predators. Their hooves are adapted to movement over steep, uneven surfaces, giving these sheep considerable agility in landscapes that would be difficult for many large mammals.
Bilby
The greater bilby (Macrotis lagotis) is a nocturnal Australian marsupial with long ears, strong forelimbs, and a talent for digging.
Its burrows provide refuge from predators and extreme temperatures, while its digging also changes the surrounding soil. New South Wales National Parks describes bilbies as ecological engineers and notes that an individual can excavate several tonnes of soil in a year.
The species once occupied a much larger area. Australia’s Department of Climate Change, Energy, the Environment and Water says the greater bilby’s range has declined by more than 80%. The agency also cautions that there is currently no robust total population estimate, which is important because older figures are sometimes repeated online as though they were precise modern counts.
Binturong
The binturong (Arctictis binturong) is an arboreal mammal of South and Southeast Asian forests. It is sometimes called a bearcat, even though it is neither a bear nor a cat.
One of its strangest characteristics is its smell, frequently compared with buttered popcorn.
Researchers studying binturong scent chemistry identified 2-acetyl-1-pyrroline, or 2-AP, in urine samples. This is also an important aroma compound associated with the familiar smell of cooked popcorn. The researchers proposed that the scent plays a role in chemical communication.
This is one of those unusual animal facts that sounds invented but has a measurable chemical explanation.
Bison
Bison are large grazing mammals with heavy forequarters, prominent shoulder humps, and thick coats.
The American bison is strongly associated with North American grasslands. Yellowstone National Park remains especially important because its bison have persisted as a continuously free-ranging population.
The National Park Service estimated nearly 5,300 bison in Yellowstone before the 2025 calving season. It also reports approximately 30,000 bison in North American public and private herds managed for conservation goals, while roughly 400,000 additional bison are raised as livestock.
Those figures should not be combined into a single “wild bison population,” because livestock and conservation herds are managed for different purposes.
Black Rhinoceros
The black rhinoceros (Diceros bicornis) is an African rhino recognizable in part by its pointed, prehensile upper lip, which is suited to browsing leaves and woody vegetation.
Its conservation history remains serious despite recent population growth.
The International Union for Conservation of Nature reported 6,788 black rhinos in Africa at the end of 2024, an increase of 5.2% from the previous year. The species remains Critically Endangered, and poaching continues to threaten its recovery.
This is a good example of why conservation categories and population trends should be considered together. A population can increase while the species remains at high risk.
Blue Whale
The blue whale (Balaenoptera musculus) is the largest animal known to live on Earth.
NOAA Fisheries reports that blue whales can reach up to 110 feet in length and 330,000 pounds in weight. Despite that enormous body size, they feed predominantly on small crustaceans called krill.
Blue whales are currently listed as Endangered under the U.S. Endangered Species Act, and modern threats include vessel strikes, fishing-gear entanglement, and ocean noise.
The blue whale creates an unusual scale contrast within the B list. The same letter includes enormous whales as well as insects weighing only a fraction of a gram.
Bobcat
The bobcat (Lynx rufus) is a medium-sized wild cat native to North America.
Its short “bobbed” tail gives the species its English name. Bobcats occupy a wide range of environments, including forests, scrublands, deserts, swamps, and areas near human development.
They generally hunt alone and consume prey such as rabbits, rodents, birds, and other small animals, although diet varies with location and opportunity.
Bonobo
The bonobo (Pan paniscus) is a great ape found naturally only in the Democratic Republic of the Congo.
Bonobos and chimpanzees are the closest living relatives of humans. WWF notes that bonobos share approximately 98.7% of their genetic material with humans and currently lists the species as Endangered.
Estimating their abundance is difficult because of remote habitat and other survey challenges. WWF gives a broad estimate of approximately 10,000 to 50,000 bonobos while emphasizing that the true population size remains poorly known.
A broad, qualified estimate is more responsible than presenting an apparently exact number that field research cannot support.
Bornean Orangutan
The Bornean orangutan (Pongo pygmaeus) lives on the island of Borneo. Like other orangutans, it is highly adapted to life in tropical forests and plays an ecological role in moving seeds through the landscape.
WWF currently classifies the Bornean orangutan as Critically Endangered and cites an approximate population of 104,700. Habitat loss, fragmentation, hunting, and the species’ naturally slow reproductive rate make recovery difficult.
Population figures for orangutans are estimates derived from field surveys and habitat models rather than literal head counts of every individual.
Other mammals that start with B include the babirusa, bandicoot, beluga whale, Bengal tiger, black bear, bongo, bottlenose dolphin, bowhead whale, brown bear, buffalo, and bushbaby.
Birds That Start With B
Birds beginning with B include powerful raptors, nocturnal hunters, colorful songbirds, seabirds, and familiar companion birds.
Bald Eagle
The bald eagle (Haliaeetus leucocephalus) is a North American bird of prey and one of the best-documented wildlife recovery stories in the United States.
The U.S. Fish and Wildlife Service estimates that the lower 48 states supported approximately 316,700 bald eagles, including 71,467 breeding pairs, based on 2018 to 2019 data. The species had fallen to only 417 known nesting pairs in the lower 48 in 1963.
Bald eagles were removed from the U.S. endangered species list in 2007 after recovery, although they remain protected under other federal laws.
The word “bald” does not mean the adult bird lacks feathers. It refers to the conspicuous white-feathered head that contrasts with its dark body.
Barn Owl
The barn owl is a nocturnal bird of prey recognizable by its heart-shaped facial disc.
That facial structure helps channel sound toward the ears. Barn owls use extremely sensitive hearing alongside vision to locate rodents and other small prey, including under low-light conditions.
The common barn owl has an exceptionally broad geographic distribution, although populations and related species can vary greatly among regions.
Blue Jay
The blue jay is a North American member of the crow family, Corvidae.
Its blue, white, and black plumage makes the bird easy to recognize, while its intelligence and complex vocal behavior connect it with other corvids such as crows, ravens, and magpies.
Blue jays eat a varied diet that can include nuts, seeds, insects, fruit, and other available foods. Their habit of carrying and caching acorns can also contribute to seed dispersal.
Budgerigar
The budgerigar, often shortened to budgie, is a small parrot native to Australia.
Wild budgerigars are typically green and yellow, while selective breeding in captivity has produced numerous color varieties. They are highly social birds and can form large flocks when food and water conditions permit.
Their popularity as companion animals should not obscure their natural history as nomadic Australian parrots adapted to environments where rainfall and food availability can be unpredictable.
Other B birds include the Baltimore oriole, barbet, barn swallow, barred owl, bee-eater, belted kingfisher, bird-of-paradise, blackbird, black-capped chickadee, bluebird, bobolink, booby, and burrowing owl.
Reptiles and Amphibians That Start With B
The B list contains snakes, turtles, frogs, lizards, and several animals whose common names are strongly associated with unusual defensive or hunting adaptations.
Ball Python
The ball python (Python regius) is a nonvenomous snake native to western and central Africa.
Its common name comes from a defensive behavior in which the snake can curl tightly around its head and neck, forming a compact ball when threatened.
Like other pythons, it subdues prey by constriction rather than venom. Small mammals and birds can form part of its natural diet.
Black Mamba
The black mamba (Dendroaspis polylepis) is a highly venomous African snake.
Its name can cause confusion because the animal’s body is generally gray, olive, or brown rather than black. “Black” refers to the dark coloration inside its mouth, which may become visible during a defensive display.
Sensational claims about black mambas often exaggerate their tendency to pursue people. Like many wild animals, they generally benefit from avoiding unnecessary conflict, although a threatened snake can defend itself and its venom makes bites a medical emergency.
Box Turtle
Box turtle refers to several terrestrial turtles famous for a hinged lower shell that allows many species to close their shell tightly when threatened.
Despite the word “turtle,” many box turtles spend much of their lives on land rather than behaving like highly aquatic freshwater turtles.
Diet varies by species and age but can include insects, worms, fungi, fruit, vegetation, and other food.
Bullfrog
The name bullfrog is used for more than one frog, although the American bullfrog (Lithobates catesbeianus) is among the best known.
Large males produce deep calls that inspired the “bull” part of the name. American bullfrogs are opportunistic predators and can consume insects, other frogs, small fish, crustaceans, and vertebrates they are capable of overpowering.
Humans have introduced them outside their native range, and in some regions they have become invasive.
Other reptiles and amphibians that start with B include the banded krait, basilisk lizard, bearded dragon, black-headed python, blind snake, boa constrictor, boomslang, Brahminy blind snake, bullsnake, Burmese python, burrowing frog, bushmaster, and bush viper.
Fish and Other Aquatic Animals That Start With B
The letter B is particularly rich in aquatic names. It includes sharks, reef fish, deep-sea species, freshwater fish, and several marine mammals that people sometimes mistakenly group with fish.
Barracuda
Barracuda refers to predatory marine fishes in the genus Sphyraena.
Their elongated bodies, strong jaws, and prominent teeth suit a fast predatory lifestyle. Different barracuda species occur in warm and tropical waters around the world.
The great barracuda is particularly well known in the western Atlantic, Caribbean, and nearby waters.
Basking Shark
The basking shark (Cetorhinus maximus) is the second-largest living fish after the whale shark.
NOAA reports that basking sharks can reach around 32 feet in length and weigh more than five tons. Despite their enormous size and wide-open mouths, they are filter feeders that consume zooplankton rather than hunting large animals.
Their appearance near the surface can cause them to be mistaken for large predatory sharks, but their feeding ecology is completely different.
Betta
Betta refers to fishes in the genus Betta. The species best known in aquariums is Betta splendens, commonly called the Siamese fighting fish.
Bettas belong to a group of fishes with a specialized labyrinth organ that allows them to obtain oxygen from air at the water’s surface. This is particularly useful in warm, oxygen-poor waters.
Domesticated bettas have been selectively bred into colors and fin shapes that can look very different from wild populations.
Blobfish
The word blobfish refers to deep-sea fishes in the family Psychrolutidae.
Their famous gelatinous appearance is often represented by photographs taken after an animal has been brought rapidly from deep water to the surface. Pressure changes can distort soft-bodied deep-sea fishes, so the familiar “blob” image does not necessarily represent their normal appearance in their natural environment.
This distinction makes blobfish a useful example of how an animal’s appearance can be misrepresented when environmental context is removed.
Blue Tang
The blue tang (Paracanthurus hepatus) is a tropical marine fish associated with coral reefs in the Indo-Pacific.
Its vivid blue body and contrasting markings make it highly recognizable. Blue tangs feed heavily on algae and other plant material, helping connect herbivorous reef fishes with the ecological processes that influence algal growth on reefs.
Blue Whale
Although it lives entirely in water, the blue whale is a mammal rather than a fish.
It breathes air through lungs, is warm-blooded, gives birth to live young, and nurses calves with milk. Its presence in an aquatic-animal section is therefore based on habitat rather than taxonomic classification.
That distinction is useful in educational searches because whales, dolphins, sharks, and large fish can look superficially similar while belonging to very different branches of vertebrate evolution.
Bluefin Tuna
Bluefin tuna refers to several closely related large tuna species, including Atlantic, Pacific, and southern bluefin tuna.
They are powerful, highly migratory fishes capable of maintaining elevated temperatures in parts of their bodies compared with surrounding seawater. This form of regional endothermy supports sustained swimming and performance across varying ocean temperatures.
The common name should therefore not be interpreted as referring to one worldwide species.
Bull Shark
The bull shark (Carcharhinus leucas) is unusual among large sharks because it can tolerate a wide range of salinities.
Bull sharks primarily inhabit marine and coastal environments but can also move into rivers and freshwater systems. Their physiology allows them to regulate salt and water balance as environmental salinity changes.
This explains reports of bull sharks far upriver and distinguishes them from most shark species.
Other fish and aquatic B animals include the Bala shark, bamboo shark, barramundi, barreleye fish, bass, beluga sturgeon, bichir, black marlin, blacktip shark, blue shark, bonefish, bowfin, brook trout, and butterflyfish.
Insects and Other Invertebrates That Start With B
The B animal list becomes much more diverse once animals without backbones are included. Barnacles, bees, beetles, spiders, octopuses, jellyfish, and butterflies represent completely different evolutionary lineages.
Barnacle
Barnacles may look like shellfish attached permanently to rocks, piers, ships, or whales, but they are crustaceans related to animals such as crabs, lobsters, and shrimp.
Most familiar adult barnacles remain attached to a surface and extend specialized appendages into the water to capture suspended food.
Their fixed adult lifestyle makes them look very different from the more mobile crustaceans people usually recognize.
Bee
Bee refers to thousands of species of insects rather than only the familiar western honey bee.
Many bee species live solitary lives rather than in large social colonies. Bees are important pollinators for flowering plants, although species differ in their preferred flowers, nesting behavior, social systems, and geographic range.
This diversity is why “bee” and “bumblebee” can both appear on a B animal list without being equivalent terms.
Beetle
Beetle describes insects in the order Coleoptera.
Their front pair of wings is modified into hardened covers called elytra, which protect the more delicate flight wings and abdomen underneath.
Beetles occupy an enormous variety of ecological niches. Some eat plants, fungi, dung, wood, or stored products, while others are predators or scavengers.
Black Widow Spider
Black widow refers to several spiders in the genus Latrodectus.
Females of some species are recognizable by dark coloration and red markings, although appearance differs among species and life stages.
Black widows possess medically significant venom, but the presence of a venomous spider does not mean every encounter leads to a bite. Bites generally occur when the animal is disturbed or trapped against the skin.
Blue-Ringed Octopus
Blue-ringed octopus describes several small octopus species known for brilliant blue markings that become conspicuous when the animal is disturbed.
The Australian Museum explains that these octopuses are generally shy and prefer to hide, yet they possess extremely potent venom containing tetrodotoxin. Human envenomation can cause severe paralysis and has resulted in fatalities.
Their small size is a useful reminder that an animal’s danger cannot be judged from body size alone.
Box Jellyfish
Box jellyfish is a broader term for jellyfish in the class Cubozoa. One particularly dangerous species is Chironex fleckeri, which occurs in tropical northern Australian waters.
The Australian Museum reports that C. fleckeri can have a bell up to 30 centimeters across and tentacles reaching up to 3 meters. Its tentacles contain specialized stinging cells used to capture prey, and serious human stings require urgent medical attention.
Not every box jellyfish species poses the same level of danger, so the name “box jellyfish” should not be treated as if every cubozoan has identical venom potency.
Bumblebee
Bumblebees are bees in the genus Bombus. Around 250 species are recognized, many of which live in social colonies and are important pollinators.
Their ability to perform buzz pollination, in which flight muscles vibrate flowers and release pollen, makes certain bumblebees particularly effective pollinators of plants whose flowers retain pollen tightly.
Bumblebees and honey bees are therefore both bees, but they represent different groups with different biology.
Butterfly
A butterfly is another broad animal name rather than a single species.
The Smithsonian estimates that approximately 17,500 butterfly species occur worldwide, including around 750 in the United States. Butterflies and moths are distinguished from other insects in part by the microscopic scales covering their wings.
Their life cycle passes through egg, caterpillar, pupa, and adult stages, making butterflies familiar examples of complete metamorphosis.
Other invertebrates beginning with B include the bagworm moth, bark beetle, bark scorpion, bed bug, beetle, blister beetle, blowfly, bombardier beetle, Brazilian wandering spider, brown recluse, and bush cricket.
Domestic Animal Breeds That Start With B
Alphabetical animal pages often become much larger once domestic breeds are counted alongside wild species.
B breeds include the Balinese cat, Barnevelder chicken, Basenji, Basset Hound, Beagle, Belgian Malinois, Belgian Tervuren, Bernese Mountain Dog, Bichon Frise, Birman cat, Boer goat, Border Collie, Border Terrier, Boston Terrier, Boxer, Brahma chicken, British Shorthair, Bulldog, Bull Terrier, and Bullmastiff.
These are genuine animal names, but they belong to a different level of classification. A Border Collie and a Beagle are breeds of the same domestic dog species rather than two independent wildlife species.
This distinction matters when comparing claims about how many B animals exist.
What Are Some Easy B Animals for Kids?
For alphabet learning, classroom activities, vocabulary exercises, or animal games, some of the easiest B animals to remember are baboon, bat, bear, beaver, bee, bison, blue whale, bobcat, bullfrog, and butterfly.
Together, they can also introduce basic animal classification. Bear, beaver, bison, blue whale, and bobcat are mammals. Bee and butterfly are insects. Bullfrog is an amphibian, while the blue whale provides a useful opportunity to explain why an aquatic animal does not have to be a fish.
A slightly more challenging B list could add barracuda, binturong, bonobo, bilby, and basking shark.
Which Animals That Start With B Are Endangered?
Several B animals face significant conservation pressure, but the degree of risk differs among species.
The black rhinoceros remains Critically Endangered. IUCN reported 6,788 individuals in Africa at the end of 2024, even after a year of population growth.
The Bornean orangutan is also Critically Endangered. WWF cites an approximate population of 104,700, although this should be understood as an estimate rather than a current direct count of every orangutan.
The bonobo is Endangered. Its population is difficult to determine accurately, with WWF giving a broad estimate of 10,000 to 50,000 animals.
The blue whale is listed as Endangered under the U.S. Endangered Species Act throughout its range. Entanglement, vessel strikes, and ocean noise remain important conservation concerns.
The greater bilby is listed as Vulnerable under Australia’s Environment Protection and Biodiversity Conservation Act. Its historical distribution has contracted by more than 80%, while introduced predators and altered fire regimes remain major threats.
Conservation numbers should always be read with their date, geography, and survey method. A Yellowstone bison estimate, for example, describes that specific population and cannot be presented as the total number of bison worldwide.
