Amabie
Amabie (アマビエ) is a legendary Japanese mermaid or merman with a bird beak-like mouth and three legs or tail-fins, who allegedly emerges from the sea, prophesies either an abundant harvest or an epidemic, and instructed people to make copies of its likeness to defend against illness. The amabie appears to be a variant or misspelling of the amabiko or amahiko (Japanese: アマビコ, アマヒコ, 海彦, 尼彦, 天日子, 天彦, あま彦), otherwise known as the amahiko-nyūdo (尼彦入道), also a prophetic beast depicted variously in different examples, being mostly as 3-legged or 4-legged, and said to bear ape-like (sometimes torso-less), daruma doll-like, or bird-like, or fish-like resemblance according to commentators.
