Guard hair in the context of "Cashmere wool"

The bat-eared fox (Otocyon megalotis) is a species of fox found on the African savanna. It is the only extant species of the genus Otocyon, and is the sister species to all other members of the tribe Vulpini. Fossil records indicate this canid first appeared during the middle Pleistocene. There are two separate populations of the bat-eared fox, each of which makes up a subspecies. The bat referred to in its colloquial name is possibly the Egyptian slit-faced bat (Nycteris thebaica), which is abundant in the region and has very large ears. Other vernacular names include big-eared fox, black-eared fox, long-eared fox, Delalande's fox, cape fox, and motlosi.

It is named for its large ears, which have a role in thermoregulation. It is a small canid, being of comparable size to the closely related cape fox and common raccoon dog. Its fur varies in color depending on the subspecies, but is generally tan-colored and has guard hairs of a grey agouti color. The bat-eared fox is found in Southern and East Africa, though the two subspecies are separated by an unpopulated region spanning approximately 1,000 km (620 mi). In its range, the bat-eared fox digs dens for shelter and to raise its young, and lives in social groups or pairs that hunt and groom together.

The mantled howler (Alouatta palliata) is a species of howler monkey, a type of New World monkey, from Central and South America. It is one of the monkey species most often seen and heard in the wild in Central America. It takes its "mantled" name from the long guard hairs on its sides.

The mantled howler is one of the largest Central American monkeys, and males can weigh up to 9.8 kg (22 lb). It is the only Central American monkey that eats large quantities of leaves; it has several adaptations to this folivorous diet. Since leaves are difficult to digest and provide less energy than most foods, the mantled howler spends the majority of each day resting and sleeping. The male mantled howler has an enlarged hyoid bone, a hollow bone near the vocal cords, which amplifies the calls made by the male, and is the reason for the name "howler". Howling allows the monkeys to locate each other without expending energy on moving or risking physical confrontation.
