The underfur is particularly thick and black in adults, while the guard hairs are lighter. The snout is grey, silver or orange. [33] The head is large, broad and heavy in proportion to the body, but the ears are proportionately smaller; the palate is wide in proportion to the skull. They do not seem to hibernate, possibly because food resources are available the whole year throughout the range. Helarctos malayanus euryspilus Horsfield, 1825 Taxonomic Serial No. [54][55][56] However they have been seen in farmlands, plantations and orchards, where they may be considered vermin. [28] The edges of the paws are tan or brown, and the soles are fur-less, which possibly is an adaptation for climbing trees. Sun bears get their name from the characteristic orange to cream coloured chest patch. [1] With the exception of Sarawak (Malaysia) and Cambodia, the sun bear is legally protected from hunting in its whole range. Being omnivores, sun bears have a broad diet including ants, bees, beetles, honey, termites and plant material such as seeds and several kinds of fruits; vertebrates such as birds and deer are also eaten occasionally. [3][8][26] It is stockily built, with large paws, strongly curved claws, small rounded ears and a short snout. Sun Bears on Borneo (Helarctos malayanus euryspilus) are sufficiently different from those on the Asian mainland and Sumatra, representing the typical form (H. m. malayanus), as to warrant subspecific differentiation (Meijaard 2004) [64] A report published by TRAFFIC in 2011 showed that sun bears, along with Asian black bears and brown bears, are specifically targeted for the bear bile trade in southeastern Asia, and are kept in bear farms in Laos, Vietnam, and Myanmar. The researchers noted the need for further study to fully resolve the relationship. [37] Cubs are born deaf with eyes closed. [45][46] They forage mostly at night. EXPORT AS CSV . [3], The phylogenetic relationships among ursid species have remained ambiguous over the years. It is mainly active during the day, though nocturnality might be more common in areas frequented by humans. The fur is generally jet-black, but can vary from grey to red. Si bien el oso malayo no es una especie en peligro de extinción si podemos afirmar que está en una situación vulnerable por la destrucción de su hábitat y la caza realizada por los humanos para el comercio, para alimentarse directamente con su carne o para uso medicinal así como por su famosa piel. The brown bear/polar bear lineage was estimated to have diverged from the two black bears/sun bear lineage around 5.54 to 6.72 million years ago; the sun bear appears to have diverged from the two black bears 5.09–6.26 mya. [4][26] The overall unique morphology of this bear—inward-turned front feet, flattened chest, powerful forelimbs with large claws—indicates adaptations for extensive climbing. [37] Oil palms are nutritious but not enough for subsistence. The Malayan Sun Bear is referred by local people as the "dog bear." Cubs younger than two months are dependent on external simulation for defecation. The tail is 3–7 cm (1–3 in) long. A crest is seen on the sides of the neck and a whorl occurs in the centre of the breast patch. It is the smallest of the bears, and one of the two species found south of the equator (the other is the spectacled bear of South America). [8][37] Sun bears stand on their hindfeet for a broader view of their surroundings or smell far-off objects; they try to intimidate their enemies by displaying the chest patch if threatened. They are short haired with deep black or brown-black fur with a horseshoe shaped marking on a chest of pale orange yellow.They have a curious gait, in that all the legs are turned inward while walking. [43], Sun bears are omnivores and feed on a broad variety of items such as ants, bees, beetles, honey, termites and plant material such as seeds and several kinds of fruits. Terms of Use    Today they have been eliminated from majority of their erstwhile range, especially in Thailand; populations are declining in most of the range countries. The hair is silky and fine, and is the shortest of all bear species, suiting their hot tropical habitat. [1] Population densities vary from 4.3 and 5.9 individuals per 100 km2 (39 sq mi) in Khao Yai National Park (Thailand) to 26 individuals per 100 km2 (39 sq mi) in the Harapan Rainforest in southern Sumatra. Two subspecies have been proposed on the basis of variations in size: [16][17] Genetic differences between the two subspecies are obscure. [1][26] Compared to other continents, southeastern Asia has undergone severe depletion in forest cover over the past few decades (by almost 12% between 1990 and 2010); this has resulted in substantial habitat loss for forest-dependent species such as sun bears. [10] In 1825, American naturalist Thomas Horsfield placed the species in a genus of its own, Helarctos. [4] Sun bears are noted for their intelligence; a captive bear observed sugar being stored in a cupboard then locked by a key, and later used its own claw to open the lock. The Malayan Sun Bears weight can range from 60 to 145 pounds, with males being slightly larger. The sun bear is named so for its characteristic orange to cream coloured, crescent-like chest patch. [39][40], Sun bears are shy and reclusive animals, and usually do not attack humans unless provoked to do so, or if they are injured or with their cubs; their timid nature led these bears to be tamed often and kept as pets in the past.
