Giraffe - Giraffa camelopardalis
The giraffe (Giraffa camelopardalis) is an African even-toed ungulate mammal, the tallest of all extant land-living animal species, and the largest ruminant. Its scientific name, which is similar to its archaic English name of camelopard, refers to its irregular patches of color on a light background, which bear a token resemblance to a leopard's spots, and its face, which is similar to that of a camel. The average mass for an adult male giraffe is 1,200 kilograms (2,6460 lb) while the average mass for an adult female is 830 kilograms (1,830 lb). It is approximately 4.3 metres (14 ft) to 5.2 metres (17 ft) tall, although the tallest male recorded stood almost 6 metres (19.7 ft).
Black Rhinoceros - Diceros bicornis
The Black Rhinoceros or Hook-lipped Rhinoceros (Diceros bicornis), is a species of rhinoceros, native to the eastern and central areas of Africa including Kenya, Tanzania, Cameroon, South Africa, Namibia, Zimbabwe, and Angola. Although the Rhino is referred to as black, it is actually more of a grey/brown/white color in appearance.
An adult Black Rhinoceros stands 132–180 cm (52–71 in) high at the shoulder and is 2.8–3.8 m (9.2–12 ft) in length, plus a tail of about 60 cm (24 in) in length. An adult typically weighs from 800 to 1,400 kg (1,800 to 3,100 lb), however unusually large male specimens have been reported at up to 2,199–2,896 kg (4,850–6,380 lb). The females are smaller than the males. Two horns on the skull are made of keratin with the larger front horn typically 50 cm (20 in) long, exceptionally up to 140 cm (55 in).
The longest known horn measured nearly 1.5 m (4.9 ft) in length. Sometimes, a third smaller horn may develop. These horns are used for defense, intimidation, and digging up roots and breaking branches during feeding. Skin color depends more on local soil conditions and the rhinoceros' wallowing behavior than anything else, so many black rhinos are typically not truly black in color. The Black Rhino is smaller than the White Rhino, and has a long, pointed, and prehensile upper lip, which it uses to grasp leaves and twigs when feeding. White Rhinoceros have square lips used for eating grass. The Black Rhinoceros can also be recognized from the White Rhinoceros by its smaller skull and ears.
Their thick layered skin protects the rhino from thorns and sharp grasses. Their skin harbors external parasites, such as mites and ticks, which are eaten by oxpeckers and egrets that live with the rhino. Such behaviour was originally thought to be an example of mutualism, but recent evidence suggests that oxpeckers may be parasites instead, feeding on rhino blood. Black rhinos have poor eyesight, relying more on hearing and smell. Their ears possess a relatively wide rotational range to detect sounds and an excellent sense of smell to alert them the presence of predators.
