vat kind of biologist you supposed to be... after graduate then come ask this kind of question.
Sharks, whales, dolphins and most fishses sleep with half their brains only most of the time, the other half still active, then switch half. Anything happen then will switch to full alertness.

Ehh really? so they swim around slow motion when the half of the brain is sleeping?
Wonder if sharks can get stroke. Hmm so if you have a brain damaged shark with half the brain not working properly (but still alive) maybe will suffocate when sleeping.

GAH! I think NUS should rescind your degree.
IF you had a shark that had all that you just described, and the shark suffocates, then you won't have any more shark to worry about will you?

我們活在一個
排骨王里頭沒有排骨
魚頭爐裡面沒有魚頭
