The whale was named after the milky-white substance spermaceti found in its head and originally mistaken for sperm.
The Sperm Whale is exceptional for its very large head, particularly in males, which is typically one-third of the animals' length.
The Sperm Whale has the largest brain of any living creature on Earth.
The brain of a mature sperm whale weighs 7 kg (15 pounds) or more.
Sperm Whales, along with bottlenose whales, are the deepest-diving mammals in the world.
They are believed to be able to dive up to 3,000 metres in depth and 2 hours in duration to the ocean floor.
