Sperm whales have an enormous square head which is up to a third of their overall body length (males have larger heads in proportion to their bodies than females). They are covered in wrinkly, grey, prune-like skin and older males are sometimes badly scarred, especially around the head. Sperm whales can be found in all the oceans of the world however they are not found in areas that are less than 200 meters deep. They feed on deep sea squid and are able to submerge up to a depth of 1000 meters and it has been documented that some have gone as deep as 2500 meters, diving straight down.

Female sperm whales can reach lengths of 12,5 meters, while males can reach 19 meters long. Adult sperm whale’s weight: 20-50 tons.
