Do fish have tongues?

Asked by: Anon

Most fish have a bony structure called the basihyal on the floor of the mouth that superficially resembles a tongue. But it doesn’t have taste buds, isn’t muscular and has very little range of motion, so it isn’t directly equivalent. It probably originally evolved to protect the ventral aorta, which lies very close to the mouth, from impacts with large, wriggly food.
