If that weren’t the case, you really only have two options:
-
Sharks maintain their height out of the water via using their pelvic fins or similar to generate lift via Bernoulli’s principle and are required to thus maintain very high speed as long as they want to stay out of the water. Think of a hydrofoil, but a shark.
-
The shark has a dramatically-lower density than water, has a greater-than-neutral buoyancy, which I suspect would create difficulties with crushing when the shark wants to dive deep.

aren't icebergs the 'icebergs of the sea'?

Nah, icebergs are the sea of the sharks.

But aren’t the seas the sharks of the seas ?
