Pinnipeds have a complex, multi-chambered stomach for digesting plant material.

Cetaceans have a highly folded cerebrum and large brain relative to body size.

Which dolphin species has the shortest rostrum of any cetacean species?

What is the family name of the sperm whale?

Marine mammals rely primarily on oxygen stored in their lungs during deep dives.

What unique fact is true for all mysticete species?

Which statement accurately describes Mysticete feeding strategy evolution?

Briefly compare and contrast the infraorders mysticeti and odontoceti making sure to provide sufficient details on the characteristics that they share in common and the differences that separate both infraorders. You should discuss a minimum of 4 characteristics when comparing and contrasting the infraorders. 

Which marine mammal group evolved earliest according to fossil records?

It is evident that marine mammals utilize sensory hairs in a variety of ways, which is reflected in the variation of hair distribution and structure of the hair follicles. Compare and contrast the different ways that sirenians, pinnipeds, and cetaceans use sensory hairs to interact with the aquatic environment around them. Make sure you describe presence/distribution of sensory hairs, how they function, and how each marine mammal taxa uses them in similar or differing ways.
