Baleen whales are the other suborder of the toothed whale species. Oxygen is pumped around its enormous body by an equally massive, four-chambered heart. We have an air-filled ear canalat the end there is an eardrum that vibrates in response to sound, which sets up a chain reaction of movement in the ear bones. Toothed whales lack the waxy plug, and the bones of their ears are not attached directly to the skull bone (an adaptation that prevents vibrations from the skull being perceived as sounds from the surrounding water). Even during deep dives, the baleen whales sounds can be heard underwater, allowing them to attract the attention of other whales that arent near the surface. So while marine mammals still have many of the same ear parts as people do, they've been modified to enable them to function in the ocean, says Pyenson, a National Geographic grantee.
