Sperm whale..(Physeter macrocephalus)
Sperm whales are toothed whales and dive to great depths to feed. They eat large organisms, mainly squids, but males are also likely to eat demersal fish including sharks and rays. They are thought to feed using clicks, which can both locate and possibly stun their prey. Dives have been known to last for over one hour and can be deeper than 1000 m. Most dives tend to last around 35 minutes however, extending down to 400 m.
