The melon is a a fatty structure located in the forehead of all cetaceans. In most toothed whales, it serves as an acoustic lens for echolocation sound production.

Comments
|
Forelimbs were probably folded against the body during rapid swimming by pelvic paddling at the sea surface and during rapid swimming by pelvic paddling and caudal undulation when submerged. On land, Rodhocetus supported itself on hoofed digits II, III, and IV of the hands and on the plantar surfaces of the feet, and probably progressed somewhat like a modern eared seal or sea lion.
