Right whales are similar to bowhead whales, but smaller. These whales are rich in blubber and have 2 blowholes. The eyes are very small and lips are large. The females are slightly larger than males, as with all baleen whales.
Calves are blue to gray colored.
Right whales have no dorsal fin and no throat grooves. They have large flippers. Right whales are skimmers, filter feeders that swim slowly with their mouth open, constantly eating. On occasion, they are also bottom feeders, eating benthic prey from the mud on the ocean floor. Right whales only long-term bonds are between mother and calf.
