Why are baleen whales called filter feeders?
Baleen whales are commonly refereed filter feeders because of the way they capture prey such as fish and krill and trap them in their baleen bristles while allowing water and other small sea sediments to escape through their baleen bristles, much like a filter.
What does it mean when a whale finds a group of prey?

How do baleen whales live?
The baleen “comb” or plate is not the only thing that sets baleen whales apart from toothed whales. They also live very different lives, usually swimming alone instead of with a group. In some cases, baleen whales may join together when they migrate, or swim long distances. They may also become more social during mating periods. Since baleen whales are very large and have thick layers of blubber, a kind of body fat, they are capable of living in extremely cold waters. Even though baleen whales are so large, they actually have very small throats, making it uncommon for them to eat large fish, squid, octopus, or other underwater animals.

As the names suggest, one type of whale has teeth. The other type has something very different, called baleen, instead of teeth.
