There are about 76 different kinds of whales and dolphins around the world.Though they live in water，whales and dolphins are not f（1）ishish .They are warm-blooded mammals （哺乳動物），like cats，dogs，and humans.Their babies are born alive and feed on mother's milk.
Mammals cannot b（2）reathereathe underwater as fish do.Most whales and dolphins must come up for air after several minutes.A few，though，can stay under for an hour or more.
All whales and dolphins are mammals called cetaceans （鯨目動物）.There are two main kinds of cetaceans - those with teeth and those w（3）ithoutithout.Toothed whales have sharp teeth that they use to catch，bite，and kill other animals.Baleen whales，on the other hand，do not have teeth.I（4）nsteadnstead ，they have mouths full of baleen （鯨須），which is used to filter （過濾） food from the water.One kind of the baleen whale，the blue whale，is the largest l（5）ivingiving thing on Earth.
All dolphins are whales，and they have teeth.Some dolphins are called dolphins and some о（6）thersthers are called whales.Killer whales，for example，are really dolphins.The killer whale is one of the most handsome animals in the sea.It doesn't look much l（7）ikeike other dolphins which are grey or all black.The killer whale is black and white，and it is the largest of the dolphins.But it is still much s（8）mallermaller than the baleen whales.
Bottlenose dolphins are probably the best known dolphins.They are the ones most often seen on TV and in ocean parks.They can be t（9）rainedrained to perform jumps，flips，and other exciting moves.During their training and while they are performing，the dolphins are usually given fish as a reward for c（10）arryingarrying out certain behaviours（行為）.However，since these are all natural behaviours to begin with，the question is，who's training whom？
