The three major groups of baleen whales are the right whales, rorquals, and the gray whales. Right whales are characterized by having no dorsal fins and no pleats or grooves on their lower jaw. Rorquals have dorsal fins and grooves on their lower jaw that aid in the expansion of the mouth for feeding purposes. Gray whales lack grooves and a distinct dorsal fin but have a dorsal bump toward the rear third of the body.
