Mystery Hour Question
Name: Jake, Canary Wharf
Question: Why don’t sea creatures get crushed by water pressure, like humans do?
Answer: Toby, Fulham
Qualification: Scuba Diver
Sea creatures are predominantly made of liquid, which means they are incompressible at those pressures.
Whereas, because humans breathe air through their lungs, their air cavities can get compressed.
