Zora (Enemy)

The River Zora (or Zola) are an evil and mischievious subspecies of Zora that hide under the water's surface (typically within rivers, hence their name) in order to surprise their victims. While still within deeper waters, they ocassionally will stick their heads beyond the surface and shoot fireballs at people, while in more shallow waters they are known to emerge fully and give chase on foot, after their foes. Unlike their peaceful cousins, the River Zora have no hint of beauty or grace. Their skin is usually scaly and green, while their maw has developed sharp fangs and whiskers akin to a catfish.

Trivia
Due to a translation error in the original Legend of Zelda, evil River Zora were called Zola. When Ocarina of Time came out, there had to be a fine line drawn between the two races (the older enemy Zora and the newer friendly species), thus the name River Zora was born. However, some fans still choose to refer to River Zora as the Zola.
