Sperm whales can hunt in total darkness under the sea but how? Steve Backshall explains how sperm whales use sound to build up a picture of their environment as he gets up close to them.

Sperm whales are among the largest, yet most elusive, creatures inhabiting deep ocean waters. Adult sperm whales undertake long, deep dives into the darkness and high pressure of the meso- and bathypelagic depths.

They do this to locate and catch approximately 1000 kg of medium-sized squid and fish each day.

The most prominent feature of the sperm whale physique is the large nasal complex, accounting for up to one-third of the body length of large males.
