The Mexican salamander that never grows up — an aquatic salamander that retains its larval features throughout adult life (a condition called neoteny), keeping its external gills as feathery plumes; it can regenerate entire limbs, spinal cord segments, and even parts of the heart and brain; critically endangered in the wild but kept by millions as a pet.
The world's smallest fox — weighing just 1–2 kg, with disproportionately enormous ears that serve as radiators in the Sahara heat and as precision directional hearing for locating prey underground.
The most widespread wild canid on Earth, an adaptable omnivore with a luxurious red coat, white-tipped tail, and a notorious reputation for cleverness.
A wild mountain goat with massive curved horns that lives on near-vertical cliff faces in the European Alps, recovered from near-extinction through 19th-century conservation.
A large, snow-adapted wild cat with characteristic ear tufts and short tail — four species spread across the northern hemisphere, with populations recovering from near-extinction in some regions.
A massive Ice Age survivor of the Arctic tundra — famous for the defensive circle it forms against wolves, its extraordinarily warm qiviut wool, and the musky odour males produce during rut.
An African ground squirrel of arid scrub and semi-deserts, with sandy or grayish fur, a long bushy tail, and a habit of using the tail as a parasol against the sun.
