The Hellenic Trench is the core habitat of the eastern Mediterranean sperm whale sub-population that numbers two to three hundred individuals. Major shipping routes running on or very close to the m depth contour along the Hellenic Trench are causing an unsustainable number of ship-strikes with sperm whales reviewed in this paper. Sperm whale sighting and density data were combined with specific information on the vessel traffic in the area e.
They also have the largest brain out of any animal known to exist. Female sperm whales on the other hand tend to be much smaller growing to lengths of 34 — 38 ft. The head of the whale contains an organ known as the spermaceti organ, hence its name, which was once believed to produce sperm, but has since been proven to serve another unknown use.
Label Me! It has a huge brain that weighs about 20 pounds 9 kg ; it is the largest brain of any animal. The sperm whale has a single blowhole that is s-shaped and about 20 inches long.
Sperm whales are icons of the deep, but despite their gigantic size and dramatic stature, their open ocean home is still mostly a mystery. Living together as a family, they can be found throughout the open ocean, spending time in the deep to find food, which makes it a challenge for scientists to document their behaviour. When the Blue Planet II team set out to try and capture this secret world, they enlisted the help of Marine Biologist Dr Shane Gero, who has been studying sperm whales for over 15 years. Until now, scientific tags have been fitted to the whales mostly to monitor their sound and movement, creating a three-dimensional model of their underwater world, but new camera technology is allowing us to immerse ourselves in the depths of the ocean as sperm whales embark on their deep-sea hunt.
The sperm whale is the largest toothed whale. Males reach 60 feet 17 m in length and the smaller females are 37 feet 12 m. They are dark gray in color, have a hump rather than a dorsal fin, and usually display their tail flukes when they dive.
The inspiration for the white whale of Moby Dick, sperm whales have the largest heads, biggest brains, and make the loudest sound of any animal on Earth. Region: Arctic. Destinations: Lofoten, Greenland, Svalbard, Iceland.

The Sperm Whale is the largest of all toothed whales, and many people immediately think of the story of Moby Dick when they see one. It is well known for the grayish color that it features. The unique body design also offers a very large head with rows of sharp teeth.
Sperm whalePhyseter catodonalso called cachalotthe largest of the toothed whaleseasily recognized by its enormous square head and narrow lower jaw. The sperm whale is dark blue-gray or brownish, with white patches on the belly. It is thickset and has small paddlelike flippers and a series of rounded humps on its back.
