North Atlantic Right Whale
The
North Atlantic Right Whale (Eubalaena glacialis) can grow up to 18 meters and weigh up to 100,000 kilograms. They were named 'right' whale by fisherman, because they thought it was the right whale to hunt, as they swim close to the shore, float when killed and 40 % of their body is blubber. Baleen whales feed with their baleen, they 'skim' the water with their mouth open. Water and prey come into the mouth of the whale, but only the water can pass throught, leaving prey like zooplankton, krill, little shrimps behind. There are about 300 Atlantic Northern Right Whales living today, almost all in the western North Atlantic, and are an endangered species.
