They are found in all oceans. Males in particular, which are known for their long-distance migrations, venture into the polar regions and marginal seas, while females, along with their young, concentrate in the tropics and subtropics and avoid surface temperatures below 15 degrees Celsius.
In August 2004, a sperm whale was observed in the Baltic Sea. However, the Baltic is too shallow for the sperm whale, which dives to great depths and does not provide it with adequate food. Sperm whales can be found year-round in the Azores, off the coast of Portugal, as well as in the Mediterranean Sea, in the Greek coastal area (population of about 200 animals).
