Answer:

The brain size of sharks is not the same in every shark species, some of them have a Y-shaped brain with two bulbs.

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 they have a good rate when compared with some mammals and birds.

In general, sharks have complex brains.
