Litter Size

How many babies does a Indo-Pacific humpback dolphin have at once? (litter size)

How many baby Indo-Pacific humpback dolphins are in a litter?

A Indo-Pacific humpback dolphin (Sousa chinensis) usually gives birth to around 1 babies.

Upon birth, they weight 5 grams (0.01 lbs) and measure 1.6 cm (0′ 1″). They are a member of the Delphinidae family (genus: Sousa). An adult Indo-Pacific humpback dolphin grows up to a size of 9.8 cm (0′ 4″).

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 Indo-Pacific humpback dolphin is 1

The Indo-Pacific humpback dolphin (Sousa chinensis; Chinese: 中華白海豚; pinyin: Zhōnghuá bái hǎitún) is a species of humpback dolphin inhabiting coastal waters of the eastern Indian and western Pacific Oceans. This species is often referred to the Chinese white dolphin in China (including Hong Kong and Macao), Taiwan and Singapore as a common name. Some biologists regard the Indo-Pacific dolphin as a subspecies of the Indian Ocean humpback dolphin (S. plumbea) which ranges from East Africa to India. However, DNA testing studies have shown that the two are distinct species. Additionally, a new species (the Australian humpback dolphin (S. sahulensis)) has just recently been split off from S. chinensis and recognized as a distinct species. Nevertheless, there are still several unresolved issues in differentiation of the Indian Ocean-type and Indo-Pacific-type humpback dolphins. In fact, the taxonomic affinities of humpback dolphins in the entire Bay of Bengal (i.e., eastern India, Sri Lanka, Bangladesh, and Myanmar) need to be urgently re-examined. There is also still some uncertainty regarding the exact taxonomic status of populations observed in mainland Malaysia and Borneo. In particular, a unique subspecies (S. c. taiwanensis) may exist in Taiwan (IUCN Red List version 3.1).
