Wildebeest
Both species of wildebeest are even-toed, horned, greyish-brown ungulates resembling cattle. Males are larger than females and both have heavy forequarters compared to their hindquarters. They have broad muzzles, Roman noses, and shaggy manes and tails. The most striking morphological differences between the black and blue wildebeest are the orientation and curvature of their horns and the color of their coats. The blue wildebeest is the bigger of the two species. In males, blue wildebeest stand 150 cm tall at the shoulder and weigh around 250 kg, while the black wildebeest stands 111 to 120 cm tall and weighs about 180 kg. In females, blue wildebeest have a shoulder height of 135 cm and weigh 180 kg while black wildebeest females stand 108 cm at the shoulder and weigh 155 kg. The horns of blue wildebeest protrude to the side, then curve downwards before curving up back towards the skull, while the horns of the black wildebeest curve forward then downward before curving upwards at the tips. Blue wildebeest tend to be a dark grey color with stripes, but may have a bluish sheen. The black wildebeest has brown-coloured hair, with a mane that ranges in color from cream to black, and a cream-coloured tail. The blue wildebeest lives in a wide variety of habitats, including woodlands and grasslands, while the black wildebeest tends to reside exclusively in open grassland areas. In some areas, the blue wildebeest migrates over long distances in the winter, whereas the black wildebeest does not. The milk of the female black wildebeest contains a higher protein, lower fat, and lower lactose content than the milk of the blue wildebeest. Wildebeest can live more than 40 years, though their average lifespan is around 20 years.
Captive white tigers
Mohini, a daughter of Mohan, was officially presented to President Eisenhower by John W. Kluge, in a ceremony at the White House on December 5, 1960, and went to live at the Lion House, in the National Zoo, in Rock Creek Park. A reporter for The New York Times described the meeting of Mohini and President Eisenhower: "The President shied noticeably when the beast roared and leaped in his direction inside the traveling cage drawn up on the White House south driveway. An eloquent "Well!" was the President's only comment for the next few seconds." T.H. Reed, the director of the National Zoo, gave this description of Mohini: "Her stripes were black, shading into brown, but her main coat was eggshell white instead of the normal rufous orange. Exotic coloring and magnificent physique made her a tiger without peer. For a two-year-old kitten she had tremendous growth-almost 190 pounds, three feet tall at the shoulders, and eight feet from nose to tail." White tigers are larger and heavier than regular orange tigers. The average length of a white tiger at birth is 53 cm, compared to 50 cm for a normal orange cub. Shoulder height is 17 cm (normal 12 cm), weight 1.37 kg (normal 1.25 kg). Dalip and Krishna, two white tigers at New Delhi Zoo, weighed 139 kg and 120 kg respectively, at two years of age. Ram and Jim, two normal colored tigers at the same zoo, weighed 106 kg and 119 kg, at the same age. Raja, the white tiger, had a shoulder height of 100 cm, at ten years of age, while Suraj, an orange tiger, had a shoulder height of only 90 cm, at 12 years of age, according to New Delhi Zoo director K.S. Sankhala. Ratna and Vindhya, orange tigresses "from the white race", who carried the white gene as a recessive (both were fathered by Mohan), were higher at the shoulder than average, measuring 87 and 88 cm, compared to a normal orange tigress named Asharfi, who measured 82 cm at the shoulder. White tigers also grow faster than orange tigers. This would have given them an advantage in the wild.
