Animals That Start With N: Names, Types and Verified Facts
Animals that start with N include the naked mole-rat, narwhal, nautilus, nēnē, newt, nighthawk, nightingale, Nile crocodile, Nile monitor, nilgai, North Atlantic right whale, northern elephant seal, northern pike, northern white rhinoceros, nudibranch, numbat, nurse shark, nuthatch, nutria, and nyala.
The letter N has fewer instantly recognizable animal names than letters such as B, C, or M, yet the animals it contains are remarkably diverse. Narwhals live among Arctic sea ice, naked mole-rats form highly organized underground societies, numbats specialize almost completely on termites, nautiluses regulate buoyancy using chambered shells, and some of the world’s rarest whales and rhinoceroses have common names beginning with N.
Several names also need a little context. Newt describes certain salamanders rather than one species. Nautilus refers to living cephalopod mollusks. Nurse shark is a shark species group, while names beginning with North American, North Atlantic, North Pacific, northern, and Norwegian greatly increase the number of possible N entries.
For this reason, there is no scientifically fixed number of animals that start with N. The total changes according to whether a list counts broad groups, individual species, regional names, subspecies, domestic breeds, alternative common names, and extinct animals separately.

Mammals That Start With N
Mammals account for many of the most interesting N animals, including Arctic whales, burrowing rodents, marsupials, antelopes, seals, rhinoceroses, bats, and animals adapted to very different climates.
Naked Mole-Rat
The naked mole-rat (Heterocephalus glaber) is a small underground rodent native to eastern Africa.
Its wrinkled, nearly hairless appearance gets attention, although its social organization is even more unusual.
Smithsonian’s National Zoo describes naked mole-rats as one of the few eusocial mammals. A colony generally contains one breeding female, the queen, while most other individuals work within the colony and help raise her offspring. Average colonies contain around 70 animals, and much larger groups have been documented.
Their enormous front teeth are closely connected with underground life.
Naked mole-rats excavate tunnels using large, continuously growing incisors. Their lips close behind those teeth, which helps keep soil from entering the mouth while they dig. Smithsonian also reports that roughly one-quarter of their muscle mass contributes to jaw closure.
The teeth even contribute heavily to sensory perception. A large part of the somatosensory region of the brain is devoted to information coming from the incisors.
Their underground tunnel systems can extend for kilometers and connect nesting areas, food sources, and designated toilet chambers.
Narwhal
The narwhal (Monodon monoceros) is an Arctic toothed whale famous for the long spiral tusk commonly carried by males.
The tusk is actually an enlarged tooth.
NOAA Fisheries explains that narwhals have two upper teeth. In most males, the left tooth grows through the upper jaw and develops into the familiar spiral structure. A tusk can reach approximately 9.8 feet, or 3 meters, and weigh more than 20 pounds.
Females occasionally develop tusks, while rare males may grow two.
The tusk appears to have several possible functions. Evidence supports a role in male social status and sexual selection, while researchers have also investigated sensory and feeding functions.
Narwhals themselves are substantial whales. NOAA reports lengths of roughly 13 to 18 feet and weights ranging from about 1,760 to 3,530 pounds.
They are also deep divers.
Narwhals have been recorded diving to approximately 3,937 feet and remaining submerged for as long as 25 minutes while feeding on Arctic fishes, squid, and shrimp.
Their lack of a tall dorsal fin may also be advantageous around sea ice, where a prominent fin could interfere with movement beneath frozen surfaces.
Nilgai
The nilgai (Boselaphus tragocamelus) is among the largest Asian antelopes.
Its natural range centers on the Indian subcontinent, although introduced populations also exist elsewhere.
Adult males differ dramatically in appearance from females.
Females generally retain a yellowish-brown coat, while mature males develop a darker blue-gray coloration. Males also possess relatively short pointed horns and a distinctive tuft of hair beneath the throat.
Animal Diversity Web reports shoulder heights of approximately 120 to 150 centimeters and body weights ranging from roughly 120 to 240 kilograms.
The difference between the sexes makes the nilgai a useful example of sexual dimorphism without requiring a separate physical-traits discussion.
Northern Elephant Seal
The northern elephant seal (Mirounga angustirostris) is the largest true seal in the Northern Hemisphere.
Adult males can become enormous.
NOAA Fisheries gives an adult weight range of roughly 1,300 to 4,400 pounds and lengths of about 10 to 13 feet.
Males also develop the enlarged nose that inspired the name.
The inflatable proboscis becomes prominent after sexual maturity and helps resonate vocal threats during the breeding season. Males compete intensely for access to females, so the structure contributes directly to reproductive communication.
This is why the large nose deserves mention. Its biological function goes well beyond appearance.
Northern White Rhinoceros
The northern white rhinoceros is a subspecies of the white rhinoceros and represents one of the most extreme conservation situations among living mammals.
Only two living northern white rhinos remain, both females named Najin and Fatu at Ol Pejeta Conservancy in Kenya.
Natural reproduction is therefore no longer possible.
Scientists are attempting to preserve the lineage through assisted reproductive technology. In April 2026, the BioRescue program announced that another embryo had been created from Fatu’s eggs, bringing the total number of pure northern white rhino embryos produced to 39.
Southern white rhinoceros females are being prepared as potential surrogate mothers.
The project shows that the phrase “two northern white rhinos left” describes the living adult animals while a separate collection of cryopreserved cells and laboratory-produced embryos forms part of the conservation effort.
Numbat
The numbat (Myrmecobius fasciatus) is a small striped marsupial native to Australia.
It is unusual among marsupials in several ways.
Numbats are active primarily during daylight and have an extremely specialized diet dominated by termites.
Australia’s environment department reports that an adult numbat may consume roughly 15,000 to 20,000 termites each day. Strong front claws expose termite galleries, while a very long tongue collects the insects.
Their feeding schedule follows termite activity, so numbats change their daily routine seasonally as soil temperature changes.
The species suffered a catastrophic historical decline due largely to introduced foxes and cats, habitat loss, and altered fire regimes.
Australia currently lists the numbat as Endangered. Conservation breeding and predator management have helped wild numbers recover substantially from an estimated low of around 300 animals during the 1980s. Perth Zoo reported in 2026 that more than 320 zoo-born numbats had been returned to wild populations.
Different current sources give somewhat different overall population figures because estimates cover different populations and use different survey methods, so a single exact national total should be treated cautiously.
Nutria
The nutria, or coypu, is a large semiaquatic South American rodent.
Its webbed hind feet and strong swimming ability suit life around wetlands, rivers, canals, and marshes.
Nutria have also been introduced far outside their original range.
In some regions they are considered invasive because heavy feeding and burrowing can damage wetlands, levees, banks, crops, and native vegetation.
Their large orange-colored incisors are characteristic rodent teeth that grow continuously throughout life.
Nyala
The nyala (Tragelaphus angasii) is a spiral-horned antelope of southeastern Africa.
Males and females look strikingly different.
Adult males commonly become slate gray and may weigh around 98 to 125 kilograms, while females are smaller and usually retain a reddish-brown coat. Only males grow the large spiraling horns, which can reach around 80 centimeters.
Nyala inhabit woodland, scrub, and savanna environments, often staying relatively close to cover and water.
Their horns contribute to display and competition between males, while the striped and spotted coat helps break up the body’s outline within vegetation.
Other mammals that start with N include the nabarlek, night monkey, ningaui, noctule bat, North American beaver, North American porcupine, North American river otter, Norway rat, and Norwegian lemming.
Birds That Start With N
Birds beginning with N include Hawaiian geese, songbirds, aerial insect hunters, seabirds, pigeons, woodland birds, and several species whose names begin with “northern.”
Nēnē
The nēnē, or Hawaiian goose (Branta sandvicensis), is native only to Hawaiʻi and is the state’s official bird.
Its conservation history is remarkable.
Only around 30 wild nēnē survived during the 1950s. Captive breeding, releases, habitat management, and predator control helped rebuild the population into the thousands. The U.S. Fish and Wildlife Service reclassified the species from Endangered to Threatened in 2019, with the change taking effect in January 2020.
Nēnē also differ physically from many familiar geese.
Their feet are less extensively webbed, fitting a bird that spends considerable time walking over lava fields, grasslands, and other terrestrial Hawaiian habitats.
The species still depends heavily on conservation because introduced predators, vehicle collisions, habitat pressures, and drought can affect populations.
Nighthawk
Nighthawks are members of the nightjar family rather than hawks.
The name reflects their evening activity and aerial hunting behavior.
Common nighthawks catch flying insects with a wide mouth while moving through the air.
Their long pointed wings support fast and maneuverable flight, and their cryptic brown-gray coloration makes resting birds difficult to notice against bark, rocks, or soil.
Nightingale
The nightingale is a small Eurasian songbird famous for an exceptionally rich and varied song.
Males use vocalizations heavily during breeding.
The bird itself has relatively plain brown plumage, which makes it a useful reminder that elaborate animal communication does not always accompany bright coloration or obvious ornamental structures.
Northern Cardinal
The northern cardinal is one of North America’s most recognizable songbirds.
Adult males generally carry bright red plumage, while females are more subdued brown with reddish highlights.
The strong conical bill is suited to handling seeds, although cardinals also eat fruit and insects.
Unlike many songbirds, both males and females sing.
Nuthatch
Nuthatches are small woodland birds known for moving along tree trunks and branches while searching for insects and seeds.
Many species can travel headfirst down tree trunks.
Strong feet and curved claws allow them to maintain their grip while moving in orientations that are difficult for many other birds.
This makes their feet biologically meaningful because the trait relates directly to feeding behavior.
Other N birds include the Nicobar pigeon, night heron, nightjar, noddy, northern flicker, northern goshawk, and northern pintail.
Reptiles and Amphibians That Start With N
N reptiles and amphibians include large African crocodilians, monitor lizards, salamanders, frogs, toads, and snakes.
Newt
Newts are salamanders, although the word commonly refers to particular members of the salamander order rather than every salamander species.
The eastern newt provides a particularly interesting example because it can pass through three visually distinct life stages.
The larva is aquatic and has external gills. It later develops into the terrestrial red eft, which has lungs, legs, eyelids, and bright orange-red coloration. After living on land, it eventually returns to water as an adult.
The red coloration also acts as a warning.
Eastern newts possess chemical defenses, and their conspicuous red spots and eft-stage coloration can signal toxicity to predators.
The change from aquatic larva to terrestrial juvenile and back to aquatic adult makes the newt especially useful for explaining that amphibian life cycles can be more complex than the familiar frog-and-tadpole example.
Nile Crocodile
The Nile crocodile (Crocodylus niloticus) is a large African crocodilian associated with rivers, lakes, wetlands, and other freshwater habitats.
Its body is built for ambush predation.
Crocodilians have eyes positioned near the top of the head and nostrils high on the snout. This arrangement allows an animal to remain almost completely submerged while continuing to watch and breathe above the surface.
A powerful muscular tail supplies most of the force during swimming.
The heavy body is covered with protective scales, while strong jaws allow Nile crocodiles to capture prey ranging from fish to large mammals.
Female crocodiles also provide more parental care than many people expect from reptiles. Crocodilians commonly guard nests and respond to calls from hatchlings.
Nile Monitor
The Nile monitor (Varanus niloticus) is one of Africa’s largest lizards.
Adults can reach approximately 2.4 meters, or nearly 8 feet, in total length, although much of that length comes from the tail.
Nile monitors are capable swimmers and climbers.
Their laterally compressed tails provide effective propulsion in water, while powerful legs and sharp claws support climbing and digging.
The forked tongue collects chemical information and transfers it to a sensory organ inside the mouth.
This combination allows the animal to function effectively around waterways while still moving and hunting on land.
Natterjack Toad
The natterjack toad is a European amphibian often recognized by a pale yellow stripe running along the back.
It tends to favor open habitats with sandy or loose soils where it can burrow.
Its relatively short legs mean it often moves with a distinctive running gait instead of relying entirely on the long jumps associated with many frogs.
Other N reptiles and amphibians include the northern alligator lizard, northern leopard frog, and numerous snakes and salamanders with northern geographic names.
Fish and Other Aquatic Animals That Start With N
The letter N includes sharks, freshwater predators, colorful aquarium fish, large river fishes, and some of the rarest whales alive.
Needlefish
Needlefish are elongated fishes with narrow bodies and long jaws lined with sharp teeth.
Many live near the surface in tropical and subtropical marine or brackish water.
Their streamlined shape supports rapid swimming, while the elongated jaws help capture small fish and other prey.
Some needlefish can leap from the water when startled, which has occasionally created hazards around fast-moving boats at night.
Neon Tetra
The neon tetra is a small freshwater fish native to South America and familiar through the aquarium trade.
A brilliant iridescent blue stripe runs along the body.
The coloration reflects light and can help individuals maintain contact with a school in the dim, tannin-stained waters of their natural habitat.
Selective breeding has produced aquarium varieties, although the wild fish is already highly distinctive.
Nile Perch
The Nile perch is an enormous freshwater predatory fish native to parts of Africa.
It can reach very large body sizes and feeds on fishes and other aquatic animals.
Its introduction to Lake Victoria became one of the world’s best-known examples of how an introduced predator can dramatically alter an aquatic ecosystem.
For this reason, the Nile perch is useful beyond a simple size fact. Its history connects animal introductions with food webs, fisheries, and biodiversity loss.
Northern Pike
The northern pike is a long-bodied freshwater predator found across northern portions of North America, Europe, and Asia.
Its elongated snout carries numerous sharp teeth.
Pike commonly remain relatively still among vegetation before accelerating toward passing prey.
The long body and rear-positioned fins support these sudden bursts of speed, making shape closely connected with ambush hunting.
Nurse Shark
The nurse shark (Ginglymostoma cirratum) is a bottom-associated shark found in warm coastal waters.
NOAA Fisheries reports lengths reaching approximately 9 feet, or 2.7 meters.
Its head has a particularly useful identification feature.
Small sensory structures called barbels project near the nostrils and help the shark investigate the seafloor while searching for prey.
The mouth sits close to the front and underside of the head, fitting a feeding style that often targets fishes and invertebrates around reefs and the bottom.
North Atlantic Right Whale
The North Atlantic right whale (Eubalaena glacialis) is one of the world’s most endangered large whales.
NOAA Fisheries currently describes the population as approximately 380 whales, with only about 70 reproductively active females. The formal October 2025 estimate placed 384 individuals alive at the start of 2024, with an uncertainty of plus 10 or minus 9.
The 2026 calving season produced encouraging news.
Researchers documented 23 mother-calf pairs, including several females returning to healthier intervals between births.
That improvement does not remove the species from danger.
Fishing-gear entanglement and vessel strikes remain the primary direct human causes of serious injury and mortality.
Adult North Atlantic right whales can reach about 52 feet and 140,000 pounds.
North Pacific Right Whale
The North Pacific right whale (Eubalaena japonica) is even larger and, in its eastern range, extraordinarily rare.
NOAA reports body lengths of approximately 45 to 64 feet and weights reaching 100 tons.
The eastern North Pacific population is among the smallest known populations of any great whale.
NOAA’s July 2026 update states that fewer than 50 animals are estimated to remain in the eastern population. The Bering Sea group is thought to number around 28 whales, and only 31 unique animals had been confirmed in the photographic catalog through 2025.
The western population is larger, probably numbering in the low hundreds, although its abundance remains poorly known.
This distinction matters because saying “only 28 North Pacific right whales remain” would incorrectly apply an eastern Bering Sea estimate to the whole species.
Insects and Other Invertebrates That Start With N
N invertebrates include ancient-looking cephalopods, colorful sea slugs, segmented worms, spiders, crustaceans, and microscopic animals.
Nautilus
A nautilus is a cephalopod mollusk related to octopuses, squid, and cuttlefish.
Its external shell makes it very different in appearance from those close relatives.
The inside of the shell contains a series of chambers.
A living nautilus occupies the largest outer chamber while older chambers behind it contain controlled amounts of gas and liquid. A narrow structure called the siphuncle helps regulate that balance, allowing the animal to change buoyancy.
This means the spiral shell functions as much more than armor.
Unlike an octopus with eight arms or most squid with ten appendages, a nautilus carries numerous small grasping structures called cirri, approaching around 100 in some descriptions.
Nightcrawler
A nightcrawler is a large earthworm rather than a separate major group of animals.
Earthworms are segmented annelid worms.
They consume organic material within soil and can affect decomposition, nutrient movement, and soil structure.
The name “nightcrawler” reflects the tendency of some large earthworms to emerge at the soil surface during humid nighttime conditions.
Nudibranch
Nudibranchs are shell-less marine gastropod mollusks commonly called sea slugs.
They are famous for extraordinary colors and body shapes.
Bright coloration can serve as warning coloration, particularly in species carrying chemical or stinging defenses.
Some aeolid nudibranchs perform an even more remarkable trick.
They eat jellyfish, corals, sea anemones, and other cnidarians and can preserve undischarged stinging structures from their prey. The stolen stinging cells are moved into specialized storage areas and later used in the nudibranch’s own defense.
This provides an unusually direct example of an animal turning another species’ weapon into part of its own defensive system.
Nursery Web Spider
Nursery web spiders belong to the family Pisauridae.
Females carry their egg sacs with their mouthparts rather than attaching the sac permanently to a web.
Close to hatching, the female constructs a silk nursery around vegetation and guards the young during their earliest stage.
The name therefore comes from reproductive behavior rather than the construction of a conventional prey-catching web.
Which Animals That Start With N Are Endangered or Threatened?
Several N animals face serious conservation risks.
The northern white rhinoceros has reached the most extreme situation. Only two living females remain, and scientists are using stored genetic material, laboratory-created embryos, and southern white rhino surrogates in an attempt to preserve the subspecies.
The North Atlantic right whale remains Endangered. The latest abundance estimate is around 380 animals, including only about 70 reproductively active females.
The North Pacific right whale is also Endangered. NOAA’s latest update estimates fewer than 50 whales in the eastern population and describes the species as among the rarest large whales.
The numbat is Endangered in Australia. Foxes, feral cats, fire, and habitat loss remain major concerns despite significant recovery work.
The nēnē presents a more encouraging story. It recovered from around 30 wild birds in the 1950s to several thousand and was federally downlisted from Endangered to Threatened.
These examples illustrate why conservation status should be attached to clearly defined species or populations. A recovery story can exist alongside continuing dependence on conservation management.
What Are Some Easy Animals That Start With N for Kids?
Some of the easiest N animals for alphabet activities, spelling lessons, and classroom projects are narwhal, newt, nighthawk, nightingale, Nile crocodile, numbat, nurse shark, nuthatch, and nutria.
These names can also introduce different animal groups.
Narwhal, numbat, and nutria are mammals. Nighthawk, nightingale, and nuthatch are birds. Newt is an amphibian, Nile crocodile is a reptile, and nurse shark is a fish.
A more advanced list could include naked mole-rat, nautilus, nēnē, nilgai, nudibranch, nyala, and North Atlantic right whale.
Domestic Animal Breeds That Start With N
Several domestic breeds have names beginning with N.
Dog breeds include the Neapolitan Mastiff, Newfoundland, Norfolk Terrier, Norwegian Buhund, Norwegian Elkhound, Norwegian Lundehund, and Norwich Terrier.
Cat breeds include the Nebelung, Norwegian Forest Cat, and Norwegian Shorthair in some registry contexts.
Livestock names include the Nigerian Dwarf goat and several regional cattle, poultry, rabbit, and horse breeds.
These are valid animal names in a broad directory, although they represent breeds rather than independent wildlife species.
A Newfoundland and Norwegian Elkhound are two breeds of domestic dog, so counting them as two biological species would distort an alphabetical species total.
Frequently Asked Questions About Animals That Start With N

Final Thoughts on Animals That Start With N
Animals that start with N may form a shorter familiar list than animals beginning with many other letters, yet they contain some extraordinary examples of evolution, behavior, and conservation.
Familiar names such as narwhal, newt, nightingale, Nile crocodile, numbat, and nurse shark sit alongside much less familiar animals. Naked mole-rats live within eusocial underground colonies. Nautiluses regulate buoyancy with chambered shells. Nudibranchs can appropriate defensive cells from animals they eat, while numbats may consume tens of thousands of termites in a single day.
