A Killer Whale
What is a whale?
Whales are huge, intelligent sea mammals. They breathe air through blow-holes into lungs (unlike fish who breathe using gills). Whales have smooth, shiny, streamlined (流线型) bodies that move easily through the water.
Classification of whales There are two types of whales alive today: toothed whales (齿鲸类) and baleen whales (须鲸类). Toothed whales have teeth and a single blowhole. They feed on eat fish and other sea mammals. Baleen whales are larger than toothed whales. They are filter feeders (滤食者) that use baleen to sieve (过滤) food, and have two blowholes.
Killer whales (虎鲸) belong to toothed whales, who are the largest of the dolphins and king of the sea, biggest carnivore (食肉 动物) of the sea, killing all kinds of animals in the sea, even the huge blue whale, like tigers on land, working in a team.
Average lifespan: 50 to 80 years Size: 7 to 9.7 m Weight: up to 6 tons
Baleen whales are characterized by having baleen plates for filtering food from water, rather than having teeth. Baleen whales are generally larger than toothed whales, and females are larger than males. This group includes the largest known animal species, the Blue Whale.
