Dall’s porpoise

Largest and fastest of all porpoises; they look like a black & white blur as they shoot past

Robin Agarwal

Dall’s porpoises are cold water porpoises and prefer deep coastal and offshore water habitats and are common in the North Pacific Ocean.

This population of these porpoises is still substantial but urgently needs protection due to the large numbers being caught in Japanese coastal whaling operations for human consumption. Negotiations between Japan and international organizations have resulted in some improvements. However, other issues, such as accidental trappings in fishing nets, ocean pollution, ship strikes, etc., still need to be addressed critically. Moreover, reliable estimates about their population and distribution are still lacking.
