Black wildebeest
The black wildebeest or white-tailed gnu ("Connochaetes gnou") is one of the two closely related wildebeest species. It is a member of the genus "Connochaetes" and family Bovidae. It was first described in 1780 by Eberhard August Wilhelm von Zimmermann. The black wildebeest is typically in head-and-body length, and the typical weight is . Males stand about at the shoulder, while the height of the females is . The black wildebeest is characterised by its white, long, horse-like tail. It also has a dark brown to black coat and long, dark-coloured hair between its forelegs and under its belly.
Dhole
In appearance, the dhole has been variously described as combining the physical characteristics of the gray wolf and the red fox, and as being "cat-like" on account of its long backbone and slender limbs. It has a wide and massive skull with a well-developed sagittal crest, and its masseter muscles are highly developed compared to other canid species, giving the face an almost hyena-like appearance. The rostrum is shorter than that of domestic dogs and most other canids. The species has six rather than seven lower molars. The upper molars are weak, being one-third to one-half the size of those of wolves and have only one cusp as opposed to between two to four, as is usual in canids, an adaptation thought to improve shearing ability, thus allowing it to compete more successfully with kleptoparasites. Adult females can weigh from , while the slightly larger male may weigh from . The mean weight of adults from three small samples was . Occasionally, dholes may be sympatric with the Indian wolf ("Canis lupus pallipes"), which is one of the smallest races of the gray wolf, but is still approximately 25% heavier on average. It stands 17–22 in (43–56 cm) at the shoulder and measures 3.0 ft (0.91 m) in body length. Like the African wild dog, its ears are rounded rather than pointed.
The general tone of the fur is reddish, with the brightest hues occurring in winter. In the winter coat, the back is clothed in a saturated rusty-red to reddish colour with brownish highlights along the top of the head, neck and shoulders. The throat, chest, flanks, and belly and the upper parts of the limbs are less brightly coloured, and are more yellowish in tone. The lower parts of the limbs are whitish, with dark brownish bands on the anterior sides of the forelimbs. The muzzle and forehead are greyish-reddish. The tail is very luxuriant and fluffy, and is mainly of a reddish-ocherous colour, with a dark brown tip. The summer coat is shorter, coarser, and darker. The dorsal and lateral guard hairs in adults measure 20–30 mm in length. Dholes in the Moscow Zoo moult once a year from March to May.
