If a Manatee and a Californian Sea lion's Brain are roughly the same size whihc mammel will have a cerebal cortex with a larger surface area and why?
How does this reflect the different feeding habits of the mammels?
Without seeking references, I would assume that the sea lion's brain would be larger, because it moves more quickly and more in 3-dimensions than two to catch its prey. As a mammal, the manatee , a vegetarian, typically swims more slowly and is in relatively shallow areas in rivers. Thus I would infer that the areas governing voluntary movement would be larger with the sea lion.
Since this is not my main area of expertise, I searched Google under the key words "manatee 'sea lion' brain" to get this possible source:
In the future, you can find the information you desire more quickly, if you use appropriate key words to do your own search.
I hope this helps. Thanks for asking.
