The ears of the long-eared hedgehog — longer than half the length of its head — are much larger than those of other hedgehogs. It lives in deserts and steps, using its astute hearing (and smell) to track down food, and its ample ears to radiate heat, staying cool in its sweltering home.

With a wingspan of almost 1 metre (3.3 ft), the spectral bat is the largest bat in the Americas and the largest carnivorous bat in the world. It's believed to find avian prey by smell and is attracted to distress calls from small bats caught in mist nets. It's also known as the "False Vampire", because it was previously thought to feed on blood.

The Japanese weasel's agility and lithe body allow it to pursue its prey anywhere; down tunnels, up trees, or into water. During winter, it spends its time pursuing rodents through snowy tunnels and, after catching and eating its target, it lays down to enjoy the warmth of its prey's burrow.

The riverine rabbit is among the rarest rabbit species in the world. Considered 'critically endangered', only around 250 individuals survive in a few areas of the Karoo Desert in South Africa — where they typically live along seasonal rivers.

Often described as ghostly, the elusive Japanese serow lives in the wooded mountains of central and southern Japan. Typically solitary, it stands on rocky outcrops, staring down at the landscape for extended periods — likely watching for predators or rivals. It can be active both day and night.

A male Visayan warty pig can become four times larger than a female. During mating season, the male uses his tusks for combat and three pairs of warty growths on his face for defence — he also grows a 23 cm (9 in) long mane to attract females. The species is only found on two Philippine islands.

Endemic to Japan, the Japanese badger — like other badgers — lives in underground dens called "setts". However, the Japanese badger is known to be more solitary, with even mated pairs often living in separate setts. It is currently unknown why this is the case.

The giant otter shrew is named for its resemblance to both an otter and a shrew, despite not actually being either. It hunts nocturnally in forest pools and streams, swimming with a laterally flattened tail, like that of a fish or crocodile — an unusual swimming method among mammals.

The dwarf mongoose — Africa's smallest carnivore — uses old termite mounds as shelter, living with a family of up to 30 individuals. When foraging for insects, these mongooses work together with hornbills; the mongooses flush out insects and the hornbills watch for aerial dangers.

The brush-tailed phascogale is a carnivorous, tree-climbing marsupial from Australia. It is able to erect the long, black hairs on the end portion of its tail — this 'bottle-brush' tail is used to draw a predator's attention away from its body.

This arboreal squirrel is exceedingly energetic, spending upwards of 75% to 96% of its time being active. Most of this time is devoted to foraging; for bark and buds in winter, flowers in spring, fruits, seeds, and insects in summer and autumn. Males will also fervently chase females as part of courtship.

The jaws of a Tasmanian devil can open to an 80-degree angle, able to deliver the strongest bite of any carnivorous mammal relative to body size. Nicknamed the "Australian hyena", the devil is a bone-crunching scavenger, gorging on dead bodies before they can fester and spread disease.
