Beaked Whale
The beaked whales are the most mysterious of all whales, as they live in the deepest parts of the ocean, far from the nearest land. There are twenty known species of beaked whales, many of which hve never been seen a live; there could be other species we have yet to discover.
Beaked whales are larger than most dolphins and porposises, but smaller than most whales; they range i size from 13 feet (4 meters) to over 42 feet (13 meters). Apart from their beak-like jaws, their teeth are easily their most most distinctive feature. Many beaked whales have teeth which remain visible when the mouth is closed. In the case of the Strap-Toothed Whale, these teeth grow so large that they actually curve over the upper jaw and prevent the whale from completely opening its mouth. Not to worry, though - Strap-Tothed Whales are still able to feed, by sucking up food just like a vacuum cleaner.
Little is known about the behavior of most beaked whales, as they spend so much of their time deep underwater in remote parts of the ocean. They tend to stay well away from boats, surfacing only for the occasional breath, and almost never breach. They feed on a diet of krill and other small fish.
Did you know that while there are whales which dive deper, no whale stays underwater as long as the Northern Bottlenose Whale? The Norther Bottlenose can stay under for as long as two hours before it has to surface for another breath, although it tends not to swim very far away when it stays down for such a long time.
