How many types of baleen sharks?

There are three recognized types of baleen sharks: the whale shark (Rhincodon typus), the basking shark (Cetorhinus maximus), and the megamouth shark (Megachasma pelagiOS). These sharks are filter feeders, using their baleen plates to strain small organisms like plankton from the water. Each species has distinct characteristics and habitats, but they all share the unique adaptation of baleen for feeding.
