Fish

A fish is a type of animal found on Earth and many other planets.

Some intelligent species seem to be descended from fish, like the Pescatons, Ockorans, Kalarians, the Dax, the Hath and Zargath's race. Damon converted humans into fish people through surgery.

Examples of non-sentient fish include pilot fish, singing fish, Aaglon sharks, fugora fish, and Gumblejack.

Fishing, the sport of catching fish, was enjoyed by the Doctor.

Fish was often served with chips on Earth.
