The Sun Bear（Helarctos malayanus）is a type of bear．People mainly find the bear in the rainforests of Southeast Asia．

The Sun Bear stands about 1.2m in length（長(zhǎng)度）．It is the smallest member of the bear family．It is often called the dog bear because of its small stature（身高）．It has a 5cm tail．It weighs（重）less than 65kg．The males are a little larger than the females．

Unlike other bears，the Sun Bear’s fur is short and smooth．This adaptation is probably due to the lowland climates．Dark black or brown-black fur covers its body，except the chest（胸部）．People can find similar colored fur around the nose，the mouth and the eves．This distinct marking gives the sun Bear its name．
