A suborder of whale s with baleen plates instead of teeth, members of the Mysticeti suborder.

Any of several whales of the suborder Mysticeti, such as the right whale and rorquals, having a symmetrical skull, two blowholes, and baleen plates instead of teeth. Also known as a "mysticete."

Suborder of whales with baleen plates instead of teeth; scientific term Mysticeti, from Greek mystax, meaning "mustache," and cetus, meaning "whale".

The baleen whales, also called whalebone whales or great whales, form the Mysticeti, one of two suborders of the Cetacea (whales, dolphins and porpoises). Baleen whales are characterized by having baleen plates for filtering food from water, rather than having teeth. This distinguishes them from the other suborder of cetaceans, the toothed whales or Odontoceti.
