Shark FAQ 3

How big is the Shark Brain?

While brain size cannot be generalized to every shark species, some of them have a Y shaped brain with two bulbs, measuring about 2 feet (60 centimeters)

Some writers have said that the shark brain is the size of a golf ball, but this is not accurate.

The brain mass to body mass ratio in sharks is much lower than humans, but a very good ratio even compared with some mammals.

In general, sharks have complex brains.

  1. I think the fascinating bit about Shark brains is that they have generally been left unchanged (short of size, as you mentioned). Nature kind of got the design right when they made sharks.

  5. that's actually interesting. I have never seen a brain with 2 bulbs. then again I never studied sharks. even insect brains are similar to those on Mammals.
