Beavers (genus Castor) are large, semiaquatic rodents of the Northern Hemisphere. There are two existing species: the North American beaver (Castor canadensis) and the Eurasian beaver (C. fiber). Beavers are the second-largest living rodents, after capybaras, weighing up to 50 kg (110 lb). They have stout bodies with large heads, long chisel-like incisors, brown or gray fur, hand-like front feet, webbed back feet, and tails that are flat and scaly. The two species differ in skull and tail shape and fur color. Beavers can be found in a number of freshwater habitats, such as rivers, streams, lakes and ponds. They are herbivorous, consuming tree bark, aquatic plants, grasses and sedges.

Beavers build dams and lodges using tree branches, vegetation, rocks and mud; they chew down trees for building material. Dams restrict water flow, forming ponds, and lodges (usually built in ponds) serve as shelters. Their infrastructure creates wetlands used by many other species, and because of their effect on other organisms in the ecosystem, beavers are considered a keystone species. Adult males and females live in monogamous pairs with their offspring. After their first year, the young help their parents repair dams and lodges; older siblings may also help raise newly born offspring. Beavers hold territories and mark them using scent mounds made of mud, debris, and castoreum—a liquid substance excreted through the beaver's urethra-based castor sacs. Beavers can also recognize their kin by their anal gland secretions and are more likely to tolerate them as neighbors.

The honey badger (Mellivora capensis), also known as the ratel (/ˈrɑːtəl/ or /ˈreɪtəl/), is a mammal widely distributed across Africa, Southwest Asia, and the Indian subcontinent. It is the only living species in both the genus Mellivora and the subfamily Mellivorinae. It has a fairly long body, with a distinctly thick-set and broad back, and remarkably loose skin, allowing the badger to turn and twist freely within it. The largest terrestrial mustelid in Africa, the honey badger measures 55 to 77 cm (22 to 30 in) long and weighs up to 16 kg (35 lb). Sexual dimorphism has been recorded in this species, with males being larger and heavier than females. It has two pairs of mammae, and an eversible anal pouch.

The honey badger is a solitary animal that can be active at any time of day, depending on the location. It is primarily a carnivorous species and has few natural predators because of its thick skin, strength and ferocious defensive abilities. Adults maintain large home ranges, and display scent-marking behavior. The species has no fixed breeding period. After a gestation of 50–70 days, a female will give birth to an average of one to two cubs that will remain under her care for 1–1+1⁄4 years. Because of its wide range and occurrence in a variety of habitats, it is listed as least concern on the IUCN Red List. In popular media, the honey badger is best known as an aggressive, intelligent animal that is fearless and tough in nature.

Skunks are mammals in the family Mephitidae. They are known for their ability to spray a liquid with a strong, unpleasant scent from their anal glands. Different species of skunk vary in appearance from black-and-white to brown, cream or ginger colored, but all have warning coloration.

While related to polecats and other members of the weasel family, skunks have as their closest relatives the Old World stink badgers.
