意味（1）

(biology, chiefly zoology) An adaptation, especially a form of coloration, that warns off potential predators.

First, the selection of red as a releaser in courtship and social chasing indicates a secondarily evolved use of aposematic coloring. It is assumed here that aposematism in this and other red-and-black heliconiids, and their correlated development of Müllerian mimicry, occurred in evolution before the development of red as a social releaser.
