Baleen whales are the largest animals on earth, yet they feed on some of the smallest animals in the ocean. Right whales do not have dorsal fins or throat grooves. The pygmy right is in a separate family although it shares simiarly characteristics to right whales.
Gray whales have their own taxonomic family, genus, and species.
They are the most coastal of the baleen whales and are often found within a few miles of shore. Each year gray whales migrate between their summer feeding grounds in the Bering, Chukchi, and Beaufort Seas to their winter breeding grounds off Baja California, Mexico. This is one of the longest migrations by a mammal species. Rorqual whales are relatively streamlined in appearance and have pointed heads and small pointed fins. A rorqual whale's throat grooves.
