In what way do teleosts and other fish benefit from having a bony operculum? it prevents water outside of the body from flowing backward into the gills when the buccal (mouth) cavity is expanded it serves as a rotating joint that allows them to rapidly project their jaws forward more rapidly it forms a joint between the head and pectoral girdle and allow for a greater amount of head rotation it prevents the brain from being damaged by the lateral bending of fish attempting to escape from the mouth

Animal Compare Animal Bone Structure to Human Bone Structure Compare Animal Limb Function to Human Limb Function Whale Whale has a much shorter and thicker humerus, radius, and ulna. Much longer metacarpals. Thumb has been shortened to a stub. The whale fin needs to be longer to help in movement through water. Thumbs are not necessary as the fins are not used for grasping.
