Teeth or Baleen?

There are 84 species of whale, dolphin and porpoises, which are also known as cetaceans. All cetaceans are split in two groups called toothed whales and baleen whales . Toothed whales have teeth, one blowhole and feed mostly on fish, squid, some of them eat marine mammals and even seabirds! Baleen whales have baleen instead of teeth. These are plates that hang from their upper jaw. These baleen plates act as a giant sieve so they can filter plankton and little fish out of the water. Baleen whales have two blowholes. Find out if the following species belong to the toothed whales or the baleen whales!
