The deer-pig of Sulawesi — one of the most anatomically bizarre pigs in the world, with upper canine tusks that grow upward through the skin of the snout and curve back toward the skull; males carry these extraordinary recurved tusks throughout life, and in older individuals the tusks can complete a full circle; a Vulnerable species of Indonesian rainforest.

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.
The "bearcat" of Southeast Asian forests — a shaggy, long-tailed civet relative that smells strongly of popcorn (from a chemical it produces to mark territory), uses its prehensile tail to hang from branches, and is one of the only mammals that can delay its own pregnancy through embryonic diapause.

A medium-sized wild cat native to North America — adaptable, secretive, and surprisingly common in suburbs and rural areas, with a stub tail giving the species its name.
