Local Name  
Size Range
Adults grow more than 1.55 m (5 ft) in length and up to 30–45 kg (65–100 lb) in weight

Environment/Habitat
Stay in shallow waters (up to 50m [160 ft]), close to the shore, in waters with soft or sandy seabeds. In exceptional cases they have been encountered as far as 160 kilometres (100 miles) off-shore in the East China and Yellow Seas, albeit still in shallow water.

Morphology/Character
The Finless Porpoise almost completely lacks a dorsal fin. Instead there is a low ridge covered in thick denticulated skin. This demonstrates that the body shape that has evolved to be the optimum for sharks, dolphins and porpoises is not the only possible body shape for a marine animal.
Adult Finless Porpoises are a uniform light grey colour. Newborn calves are mostly black with grey around the dorsal ridge area, becoming fully grey after 4–6 months.



Biology
Males become sexually mature at around 4–6 years of age, and females at around 6–9 years of age.
Finless Porpoises are reported to eat fish and shrimp in the Yangtze River, and fish, shrimp and squid in the Yellow Sea/Bohai area and off Pakistan. In Japanese waters they are known to eat fish, shrimp, squid, cuttle fish and octopuses. Finless Porpoises are opportunistic feeders utilising various kinds of available food items available in their habitat. Seasonal changes in their diets have not been studied. They also apparently ingest some plant material when living in estuaries, mangroves, and rivers including leaves, rice, and eggs deposited on vegetation.
