Fishman
Fishmen are wise and witty creatures that can be found all across the Great Sea. They know much about the sea and will give Link many tips and words of knowledge about everything. They are also great cartographers and will fill in portions of the Sea Chart for Link in exchange for a small dinner.
Strangely, one of these fishmen associated regularly with a woman named Gillian who worked at the Cafe on Windfall Island.
The origins of the Fishmen remain a mystery; did they evolve from some other life form? Some believe they are descendants of Deku Scrubs, or that they are an offshoot of the Zora race, but this is merely speculation. Interestingly, the first time Link feeds All-Purpose Bait to a Fishman, he asserts to the King of Red Lions that his "debt is repaid". This may indicate that the Fishmen are in fact the remnants of one of the tribes of Hyrule, possibly having been magically altered into their current form as some kind of punishment.
