No chips with this one.
The most poisonous fish in the world is the Stone fish

But you'll need extra chips for this...
The largest known fish in the sea is the Whale Shark. It weighs up to 20 tons and grows to a length of 40 feet.

Not just a triffle.
Jelly Fish, not sharks, are the deadliest killer in oceans and seas. A certain kind of box jelly fish kills more people than all the shark species do put together.

The elephant snout, an African fish, communicates with other fish by emitting an electrical signal, sort of a fish's version of Morse Code
