Capodoglio (Physeter macrocephalus)

The Sperm whale is the largest predator that currently exists on Earth and owes its name to an organ on its head, the spermaceti, which is filled with an oily substance.

Males can reach 18 meters in length.

It is very difficult to observe it on the surface as it is able to dive for more than two hours and at depths exceeding 2000 m. Usually, however, his dives last less than half an hour, during which the depths are never exceeded 500 m.

He is not a great swimmer, generally moving at a speed not exceeding 4 knots (7.5 km/h) and only for short stretches has he been seen to exceed 15 knots. The behavior on the surface is very different from that of fin whales: the sperm whale remains visible all the time, breathing with great regularity (5-6 puffs per minute). The duration of permanence on the surface is closely related to the duration of the previous dive. Particularity of the sperm whale’s blow is that it is low and inclined to one side. At the end of a breathing sequence, the sperm whale vertically lifts its tail out of the water and dives. The main component of the sperm whale’s diet is squid.
