Risso's Dolphin * Risso-dolfyn * Grampus Griseus

The average length is 10 feet (3.0 m), however some specimens can exceed 13 feet (4.0 m). [11] The male dolphins are a little bit bigger than females. This species is the largest of the "dolphin" species, weighing between 300 and 500 kilograms (660 and 1,100 pounds).

They dive to depths of 600 metres in pursuit of prey. Usually traveling in pods of between 10 and 51, these dolphins can occasionally create "super-pods" with up to a few thousand members.

There have been documented cases of these dolphins being trapped in seine-nets and gillnets all over the world, just like other dolphins and other marine species.
