Common Animal Names Starting with U
Animals whose names start with U include mammals, birds, reptiles, fish, and marine animals from different parts of the world. Although U animal names are relatively uncommon, learning them can build vocabulary and introduce learners to a wider range of wildlife.
Uakari
A uakari is a small South American monkey recognized by its short tail and distinctive bare face. It mainly lives in the flooded forests of the Amazon Basin and feeds on fruits, seeds, leaves, and insects.
Uguisu
The uguisu, also called the Japanese bush warbler, is a small bird native to East Asia. It has brownish-green feathers and is particularly well known for the male’s clear, distinctive song.
Umbrellabird
An umbrellabird is a tropical bird named for the large umbrella-like crest of feathers on its head. It inhabits rainforests in Central and South America and mainly eats fruits and small animals.
Upland Goose
The upland goose is a large goose native to southern South America and the Falkland Islands. It commonly inhabits open grasslands, where it feeds primarily on grasses and other vegetation.
Upland Sandpiper
The upland sandpiper is a slender migratory bird with long legs, a small head, and mottled brown feathers. It prefers open grasslands rather than the wet coastal habitats associated with many other sandpipers.
Urial
The urial is a wild sheep native to mountainous and dry regions of Central and South Asia. Males have large curved horns, while both sexes have strong bodies adapted to rocky terrain.
Uromastyx
A uromastyx is a sturdy desert lizard recognized by its thick, spiny tail. These reptiles inhabit dry regions of Africa and Asia and feed mainly on leaves, flowers, seeds, and other plant material.
Unau
The unau, also known as the southern two-toed sloth, is a slow-moving mammal native to South America. It spends much of its life in trees and uses its long curved claws to grip branches.
Unicornfish
A unicornfish is a tropical marine fish named for the horn-like projection found on the forehead of some species. It lives around coral reefs and rocky coastal areas, where many species feed mainly on algae.
Uaru
The uaru is a freshwater cichlid fish native to rivers in the Amazon Basin. Its flattened body and distinctive markings make it recognizable, and its diet includes plant material and small aquatic organisms.
Uinta Ground Squirrel
The Uinta ground squirrel is a small burrowing mammal found in parts of the western United States. It inhabits meadows and grasslands and feeds on grasses, seeds, leaves, and other vegetation.
Uintatherium
Uintatherium was a large prehistoric mammal that lived during the Eocene Epoch. It had a massive body, unusual bony projections on its skull, and large canine teeth.
Ulysses Butterfly
The Ulysses butterfly is a large tropical butterfly famous for the brilliant blue coloring on its wings. It occurs in northeastern Australia and nearby regions and commonly inhabits tropical rainforest environments.
Underwing Moth
Underwing moths are moths known for their brightly colored hindwings, which remain hidden beneath more subdued forewings while resting. The sudden display of the hindwings can help confuse potential predators.
Urchin
A sea urchin is a small marine animal with a rounded body covered in movable spines. It lives on ocean floors and rocky reefs and usually feeds on algae and other organic material.
Urechis
Urechis is a genus of marine spoon worms with soft, cylindrical bodies that live in burrows beneath sandy or muddy seafloors. These animals collect tiny food particles from the surrounding water.
Upland Chorus Frog
The upland chorus frog is a small frog found in parts of North America. Its striped or mottled body provides camouflage in grassy habitats, temporary wetlands, and areas near shallow water.
Utah Prairie Dog
The Utah prairie dog is a burrowing rodent native to southwestern Utah in the United States. It lives in colonies and mainly eats grasses, flowers, seeds, and other vegetation.
Uluguru Bushshrike
The Uluguru bushshrike is a rare bird associated with mountain forests in Tanzania. Its restricted geographic range makes the protection of its forest habitat particularly important for its survival.
Unadorned Rock-Wallaby
The unadorned rock-wallaby is a medium-sized marsupial native to northeastern Australia. Its powerful hind legs and long tail help it move efficiently across steep, rocky habitats.
