Zora

Zoras are a race of underwater creatures. They first appeared in Zora's River in A Link To The Past but are more remembered for their apperance in Ocarina of Time in Zora's Domain. Fins, flippers, fish-like tails, gills, scales, they are a mix-breed between marine animals and human-like creatures. Their actual orgin up till now, remains a mystery. Although several speculations appear regarding the ideas of evolution from the Triforce in order to keep the world in balance.

In A Link To The Past there is a character called the Great Zora who sells Link his flippers for the hefty price of 500 Rupees

A special breed of Zoras is called "Zoran Heroes". They are more powerful and faster than your average Zoras. They have blades that can cut flesh easily, and their electric discharge can stun most enemies. Controlling them are like controlling a jet plane, only, they swim through water at high speed with beautiful movements instead of through air.

In Majora's Mask the Zora lived in the Great Bay Area, in the south of Termina. Link learned to transform himself in a Zora named Mikau by using the Zora Mask.

Tattoos may also be seen on Zoras and Zoran Heroes. Some tattoos may symbolize courage and bravery, and others symbolize death and after life.

There are also evil Zoras which are known as River Zoras

It is largely believed that the Zoras were the ancestors of the Rito(The Wind Waker) however there is perhaps not enough information to fully validate this claim aside from the few hints givin in The Wind Waker
