Here are some key characteristics of mysticetes:
* Baleen plates: These are keratin plates that hang from the upper jaw, acting like a filter to strain small prey from the water.
* Lack of teeth: Mysticetes do not have teeth, instead relying on baleen for feeding.
* Large size: Many mysticetes are the largest animals on Earth, including the blue whale, the fin whale, and the humpback whale.
* Filter feeding: They feed by swimming through the water with their mouths open, using their baleen plates to trap krill, plankton, and other small organisms.
* Vocalizations: Mysticetes are known for their complex and often loud vocalizations, which are used for communication, navigation, and finding food.
* Migration patterns: Many mysticetes migrate long distances between breeding and feeding grounds.
