Some Opisthobranchs evolved with textures and colors that mimick surrounding plants to avoid predators. Others, as seen especially well on the nudibranchs chromodorids, have an intensely bright and contrasting color pattern that makes them especially conspicuous in their surroundings. This is believed to be an example of aposematic coloration; the shockingly bright coloration which warns potential predators that their prey-to-be is distasteful or poisonous.
