What are the 4 major parts of the shark’s brain?

How big are great white shark brains?
about two feet
Sharks’ unique Y-shaped brains weigh around 1.2 ounces, comprising about . 008% of total body weight. For comparison, the human brain — which weighs an average of 48 ounces — makes up 1.9% of total body weight. Including the olfactory bulbs and brainstem, great whites’ brains measure about two feet in length.
