The Right whale is a baleen whale with a large, bow-shaped head and an arched mouth.
Right whales are similar to bowhead whales , but smaller.
The eyes are very small, the lips are large, and there are 2 blowholes. They have no dorsal fin and no throat grooves. The females are slightly larger than males, as with all baleen whales. 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.
