Garahna

Garahna are smaller purple versions of a Desbreko that are spawned by Gyorg after a few good hits. These creatures, although weak, can be very aggravating. If Link falls in the water, the Garahna swarm will sense him immediately, no matter where they were in the water previous to his descent. This, and their persistence, makes them a deadly, although annoying enemy.

The greatest threat to them is a blast from Zora Link's electric barrier.

Trivia

 * Garahana seems to be a portmanteau of the words and, two types of fish.
