The term 'toothed whale' refers to a type of whale that has teeth, as opposed to baleen whales which have baleen plates instead. One example of a toothed whale is the ORCA, also known as the killer whale, which is a 4-letter word. Orcas are the largest species of the dolphin family and are found in all oceans around the world. They are highly intelligent and social animals, and are known for their distinctive black and white markings.
