Toothed whale water. They also have glands on the eyelids and outer corneal layer that act as protection for the cornea. The olfactory lobes are absent in toothed whales, and unlike baleen whales, they lack the vomeronasal organ, suggesting they have no sense of smell. Toothed whales are not thought to have a good sense of taste, as their taste buds are atrophied or missing altogether. However, some dolphins have preferences between different kinds of fish, indicating some sort of attachment to taste. Toothed whales are capable of making a broad range of sounds using nasal airsacs located just below the blowhole.
Toothed whale and insulation from the harsh climates. Calves are born with only a thin layer of blubber, but some species compensate for this with thick lanugos. Toothed whales have also evolved the ability to store large amounts of wax esters in their adipose tissue as an addition to or in complete replacement of other fats in their blubber. They can produce isovaleric acid from branched chain fatty acids (BCFA). These adaptations are unique, are only in more recent, derived lineages and were likely part of the transition for species to become deeper divers as the families of toothed whales (Physeteridae, Kogiidae,
