Lessons 6 & 7 | Adaptations
Lesson 6 | BlubberAll cetaceans have a layer of blubber under their skin. The thickness of the blubber has a direct impact on where the species can live. Tropical species might only have an inch of blubber; Arctic species might have 12 or more inches of blubber.

Lesson 7| Feeding
Cetaceans are divided into two categories based on how they obtain their food. There are filter feeders, called mysticetes, that use plates of baleen to strain small organisms, usually zooplankton, from the water. There are toothed hunters, called odontocetes, that eat squid, octopus, and fish. They use echolocation to find their prey, and then get close enough to it to swallow it without chewing.
