They are *perhaps* identifiable to the genus level if there is a very large sample size. The thick blubber helps keep the cold/freezing temperatures of the outside water away from the whales vital organs and can even protect whales against attacks from predators such as sharks and killer whales. The defining characteristic of cetaceans is a thick and dense lip (pachyosteosclerotic involucrum) of an ear bone (the tympanic). Dorsal fins can vary greatly in terms of shape and size depending on the whale species, and while many species possess a dorsal fin, there are some exceptions, such as the sperm whale and beluga whale, which have no dorsal fin at all.

In whales, the bones housing the middle and inner ears are separated from the skull, and that's part of the mechanism that isolates each ear from each other and from the skull, and they're. It can get up to 6 feet tall. The groundbreaking promise of cellular housekeeping. This giant nose is actually an elaborate sound-generating device. This increased speed allows whales (with their highly attuned sense of hearing) to have a significant advantage in the aquatic world over other animals that do not rely as heavily on sound. For scientists, this important part cinched the idea that Ambulocetus was a whale in the first place. In terms of fossil balaenopterids (which are taxonomically speaking a complete nightmare), there are several species which have identical bullae but distinct crania, and several species with bullae identical to extant balaenopterids. They use instead the lower jawbone to transmit vibrations to the ear complex (something like what many snakes do).
