Litter Size

How many babies does a Sun bear have at once? (litter size)

How many baby Sun bears are in a litter?

A Sun bear (Helarctos malayanus) usually gives birth to around 1 babies.

Each of those little ones spend around 98 days as a fetus before they are released into the wild. Upon birth, they weight 325 grams (0.72 lbs) and measure 3.4 cm (0′ 2″). They are a member of the Ursidae family (genus: Helarctos). An adult Sun bear grows up to a size of 1.22 meter (4′ 1″).

To have a reference: Humans obviously usually have a litter size of one ;). Their babies are in the womb of their mother for 280 days (40 weeks) and reach an average size of 1.65m (5′ 5″). They weight in at 62 kg (137 lbs), which is obviously highly individual, and reach an average age of 75 years.

The average litter size of a Sun bear is 1

The sun bear (Helarctos malayanus) is a species in the family Ursidae occurring in the tropical forests of Southeast Asia. It is the smallest bear, standing nearly 70 cm (28 in) at the shoulder and weighing 25–65 kg (55–143 lb). It is stockily built, with large paws, strongly curved claws, small rounded ears and a short snout. The fur is generally jet-black, but can vary from grey to red. Sun bears get their name from the characteristic orange to cream coloured chest patch. Its unique morphology—inward-turned front feet, flattened chest, powerful forelimbs with large claws—suggests adaptations for climbing.The most arboreal (tree-living) of all bears, the sun bear is an excellent climber and sunbathes or sleeps in trees 2 to 7 m (6.6 to 23.0 ft) above the ground. It is mainly active during the day, though nocturnality might be more common in areas frequented by humans. Sun bears tend to remain solitary but sometimes occur in pairs (such as a mother and her cub). They do not seem to hibernate, possibly because food resources are available the whole year throughout the range. 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. They breed throughout the year; individuals become sexually mature at two to four years of age. Litters comprise one or two cubs that remain with their mother for around three years.The range of the sun bear is bound by northeastern India to the north and extends south to southeast through Bangladesh, Cambodia, Myanmar, Laos, Thailand and Vietnam in mainland Asia to Brunei, Indonesia and Malaysia to the south. These bears are threatened by heavy deforestation and illegal hunting for food and the wildlife trade; they are also harmed in conflicts with humans when they enter farmlands, plantations and orchards. The global population is estimated to have declined by 35% over the past three decades. The IUCN has listed this species as Vulnerable.
