Sambar deer
The sambar (Rusa unicolor) is a large deer native to the Indian subcontinent, South China and Southeast Asia that is listed as a vulnerable species on the IUCN Red List since 2008. Populations have declined substantially due to severe hunting, local insurgency, and industrial exploitation of habitat.
The name "sambar" is also sometimes used to refer to the Philippine deer called the "Philippine sambar", and the Javan rusa called the "Sunda sambar".
Genetic analysis shows that the closest living relative of the sambar is most likely the Javan rusa of Indonesia. This is supported by reports that sambar can still interbreed to produce fertile hybrids with this species.
Fossil sambar are known from the early Pleistocene, although they are very similar in form to early deer species from the Pliocene, with less of a resemblance to more modern cervines. The species probably arose in the tropical reaches of southern Asia, and later spread across its current range. Epirusa and Eucladoceros have both been proposed as possible ancestors of the living species and its closest relatives.
The nominate subspecies of the sambar in India and Sri Lanka are the largest of the genus, with the largest antlers both in size and in body proportions. The South China sambar of Southern China and mainland Southeast Asia is probably second in terms of size, with slightly smaller antlers than the Indian sambar. The Sumatran sambar that inhabits the Malay Peninsula and Sumatra and the Bornean sambar seem to have the smallest antlers in proportion to their body size. The Formosan sambar is the smallest subspecies, with antler-body proportions more similar to the South China sambar.
Currently, seven subspecies of sambar are recognised, although many others have been proposed.
The appearance and the size of the sambar vary widely across its range, which has led to considerable taxonomic confusion in the past; over 40 different scientific synonyms have been used for the species. In general, they attain a height of 102 to 160 cm (40 to 63 in) at the shoulder and may weigh as much as 546 kg (1,204 lb), though more typically 100 to 350 kg (220 to 770 lb). Head and body length varies from 1.62 to 2.7 m (5.3 to 8.9 ft), with a 22 to 35 cm (8.7 to 13.8 in) tail. Individuals belonging to western subspecies tend to be larger than those from the east, and females are smaller than males. Among all living cervid species, only the moose and the elk can attain larger sizes.
The large, rugged antlers are typically rusine, the brow tines being simple and the beams forked at the tip, so they have only three tines. The antlers are typically up to 110 cm (43 in) long in fully adult individuals. As with most deer, only the males have antlers.
