Gaur - Bos gaurus
The gaur (Bos gaurus), also called Indian bison, is a large bovine native to South Asia and Southeast Asia. The species is listed as vulnerable on the IUCN Red List since 1986 as the population decline in parts of the species' range is likely to be well over 70% over the last three generations. Population trends are stable in well-protected areas, and are rebuilding in a few areas which had been neglected. The gaur is the largest species of wild cattle, bigger than the African buffalo, the extinct aurochs, and wild water buffalo. The domesticated form of the gaur, Bos frontalis, is called gayal or mithun. The Malayan gaur is called seladang, and the Burmese gaur is called pyoung. The gaur has a head-and-body length of 250 to 330 cm (8.2 to 10.8 ft) with a 70 to 105 cm (28 to 41 in) long tail, and is 165 to 220 cm (5.41 to 7.2 ft) high at the shoulder. Weight is 650 to 1,000 kg (1,400 to 2,200 lb). Males are about one-fourth larger and heavier than females. Body weight may reach 1,500 kg (3,300 lb). The gaur has a high convex ridge on the forehead between the horns, which bends forward, causing a deep hollow in the profile of the upper part of the head. There is a prominent ridge on the back. The ears are very large; the tail only just reaches the hocks, and in old bulls the hair becomes very thin on the back. In colour, the adult male gaur is dark brown, approaching black in very old individuals; the upper part of the head, from above the eyes to the nape of the neck, is, however, ashy gray, or occasionally dirty white; the muzzle is pale coloured, and the lower part of the legs are pure white or tan. The cows and young bulls are paler, and in some instances have a rufous tinge, which is most marked in individuals inhabiting dry and open districts. The tail is shorter than in the typical oxen, reaching only to the hocks. The animals have a distinct ridge running from the shoulders to the middle of the back; the shoulders may be as much as 12 centimetres (5 in) higher than the rump. This ridge is caused by the great length of the spinous processes of the vertebrae of the fore-part of the trunk as compared with those of the loins. The hair is short, fine and glossy, and the hooves are narrow and pointed. Horns grow to a length of 60 to 115 cm (24 to 45 in). Both sexes carry horns, which grow from the sides of the head, curving upwards. They are regularly curved throughout their length, and are bent inward and slightly backward at their tips. The colour of the horns is some shade of pale green or yellow throughout the greater part of their length, but the tips are black. A bulging grey-tan ridge connects the horns on the forehead. The horns are flattened to a greater or less degree from front to back, more especially at their bases, where they present an elliptical cross-section; this characteristic is more strongly marked in the bulls than in the cows. Gaur have highly muscular bodies, with distinctive dorsal ridges and large dewlaps, forming a very powerful appearance. Dorsal ridges and dewlaps of females are less developed. Gaur are said to look like water buffalo at the front and domestic cattle at the back due to their heavily muscled and enlarged forequarters compared to their relatively small hindquarters. They are the heaviest and most powerful of all wild cattle, and are among the largest living land animals. Only elephants, rhinos and hippos consistently grow larger, and the weight of the largest subspecies of gaur roughly matches that of the giraffe.
Saltwater Crocodile - Crocodylus porosus
The saltwater crocodile, also known as estuarine or Indo-Pacific crocodile, (Crocodylus porosus) is the largest of all living reptiles. It is found in suitable habitats in Northern Australia, the eastern coast of India and parts of Southeast Asia. The saltwater crocodile has a longer muzzle than the mugger crocodile: its length is twice its breadth at the base. The saltwater crocodile has fewer armor plates on its neck than other crocodilians, and its broad body contrasts with that of most other lean crocodiles, leading to early unverified assumptions that the reptile was an alligator. Saltwater crocodile skull from The Museum of Zoology, Saint PetersburgNewly hatched saltwater crocodiles measure about 25 to 30 centimetres (9.8–12 in) long and weigh an average of 70 grams (2.5 oz). Males reach sexual maturity at around 3.3 metres (11 ft) at around 16 years of age, while females reach sexual maturity at 2.1 metres (6.9 ft) and 12–14 years. An adult male saltwater crocodile's weight is 409 to 1,000 kilograms (900–2,200 lb) and length is normally 4.1 to 5.5 metres (13–18 ft). However, mature males can exceed 6 metres (20 ft) and weigh more than 1,000 kilograms (2,200 lb) and this species is the only extant crocodilian to regularly reach or exceed 4.8 metres (16 ft). Weight can vary enormously based upon condition and age, older males tending to outweigh younger ones since they maintain prime territories with access to better, more abundant prey. For example, crocodiles at 4.8 metres (16 ft) long have ranged in mass variously from 522 kilograms (1,150 lb) to 1,000 kilograms (2,200 lb). This species has the greatest sexual dimorphism of any modern crocodilian, with females being much smaller than males. Typical female body lengths in the range of 2.3 to 3.5 metres (8–11 ft). The largest female on record measured about 4.2 metres (14 ft). The mean weight of the species as a whole is roughly 450 kilograms (1,000 lb). Saltwater crocodile outside Cairns, QueenslandThe largest size saltwater crocodiles can reach is the subject of considerable controversy. The longest crocodile ever measured snout-to-tail and verified was the skin of a dead crocodile, which was 6.2 metres (20 ft) long. As skins tend to shrink slightly after removal from the carcass, this crocodile's living length was estimated at 6.3 metres (21 ft), and it could have weighed more than 1,000 kilograms (2,200 lb). Incomplete remains (the skull of a crocodile shot in Orissa)[ have been claimed to come from a 7.6-metre (25 ft) crocodile, but scholarly examination suggested a length no greater than 7 metres (23 ft). There have been numerous claims of crocodiles in the 9-metre (30 ft) range: the crocodile shot in the Bay of Bengal in 1840, reported at 10 metres (33 ft); another killed in 1823 at Jalajala on the main island of Luzon in the Philippines reported at 8.2 metres (27 ft); a reported 7.6 metres (25 ft) crocodile killed in the Hooghly River in the Alipore District of Calcutta. However, examinations of these animals' skulls actually indicated animals ranging from 6 to 6.6 metres (20–21.7 ft). A crocodile shot in Queensland in 1957 was reported to be 8.63 metres (28.3 ft) long, but no verified measurements were made and no remains of this crocodile exist. A "replica" of this crocodile has been made as a tourist attraction. Many other unconfirmed reports of crocodiles exceeding 8 metres (28+ ft) have been made but these are highly unlikely. With recent restoration of saltwater crocodile habitat and reduced poaching, it is possible that 7-metre (23 ft) crocodiles are alive today. Guinness has accepted a claim of a 7-metre (23 ft), 2,000 kg (4,400 lb) male saltwater crocodile living within Bhitarkanika Park in the state of Orissa, India, although, due to the difficulty of trapping and measuring a very large live crocodile, the accuracy of these dimensions has yet to be verified.
