A large freshwater reptilian predator native to the southeastern United States and a small enclave in eastern China — distinct from crocodiles in habitat, snout shape, and temperament.
A long-snouted, toothless mammal with a sticky tongue that flicks 150 times per minute — eating exclusively ants and termites, with the giant anteater of South America consuming up to 35,000 insects daily.
A massive omnivorous mammal with the broadest range of any bear species, including the grizzly and Kodiak subspecies, capable of hibernating for half the year.
A massive aquatic rodent — North America's largest rodent — that fundamentally reshapes landscapes through dam-building, creating wetlands that support biodiversity and modern landscape restoration efforts.
Slender, antlered ruminants found across nearly all continents — from the white-tailed deer of North America to the European red deer to tropical muntjacs — among the most successful large mammals in human-altered landscapes.
The largest cat in the Americas and the third-largest in the world, a powerfully built ambush predator with the strongest pound-for-pound bite force of any big cat.
A primate family endemic to Madagascar — over 100 species evolved in isolation for 60+ million years, ranging from the tiny mouse lemur to the dramatic ringtailed lemur, all critically threatened by deforestation.
A large marine crustacean — once a poor person's food in colonial New England, now an iconic luxury seafood and the foundation of major Maritime fisheries on both sides of the North Atlantic.
The national animal of Pakistan — a large wild goat of the Himalayas and Hindu Kush with spectacular spiral horns that in old males can reach 160 cm; the horns spiral outward in a tight corkscrew, unique among wild goats; the markhor lives on vertiginous cliff faces inaccessible to most predators and is revered in the region — its Farsi name means "snake eater," though it does not actually eat snakes.
The wild ass of Asia — a fast, slender-legged equid midway between a horse and a donkey, the onager is built for speed across open desert steppe; in short sprints it can reach 70 km/h, making it one of the fastest land animals; populations have been severely reduced by hunting and habitat loss across most of their historical range; the Indian wild ass subspecies survives mainly in the Little Rann of Kutch.
A marine mustelid that floats on its back and uses stones as tools to crack shellfish, with the densest fur of any mammal and a key role in kelp-forest ecology.
The only deer species in which both males and females grow antlers — domesticated for thousands of years by Arctic peoples for meat, milk, hide, and transport; famous in Western culture as Santa Claus's sleigh-pullers, based on real Sámi traditions of reindeer herding.
A diverse order of amphibians with elongated bodies and tails — about 700 species worldwide, capable of regenerating limbs, organs, and even portions of the brain.
A shaggy, long-snouted bear of the Indian subcontinent — specialised as a termite and ant eater, with long curved claws for tearing open mounds, a mobile lower lip and long tongue for extracting insects, and the ability to close its nostrils to keep out dust; the sloth bear's noisy sucking sounds as it vacuums up termites can be heard from 100 metres away.
The world's smallest bear — a tree-climbing, honey-obsessed omnivore from Southeast Asia with an extraordinarily long tongue, a chest patch shaped like a rising sun, and an unexpectedly expressive face.
A large, prehistoric-looking mammal from South America and Southeast Asia with a short prehensile trunk — one of the oldest surviving large-mammal body plans on Earth, more closely related to horses and rhinos than to pigs.
The primate with the largest eyes relative to body size of any mammal — a tiny nocturnal primate of Southeast Asian forests whose enormous, fixed eyes cannot move in their sockets (the animal must rotate its entire head to change direction of gaze); each eye is as large as its brain; it is the only entirely carnivorous primate, eating insects, lizards, and small birds.
The largest cat species, an apex predator with distinctive orange-and-black stripes, native to Asian forests, grasslands, and mangroves.
The ancestor of the domestic pig — a powerfully built, tusked omnivore with coarse grey-black bristles that has recolonised much of Europe and Asia; a major game animal, agricultural pest, and ecological engineer whose rooting transforms forest floors.
