The tropical green seaweed Avrainvillea longicaulis is a low preference food for coral-reef fishes, and it produces a brominated diphenylmethane derivative called avrainvilleol that significantly deters feeding by reef fishes in field bioassays. In contrast to the pattern for fishes, the ascoglossan gastropod Costasiella ocellifera and the crab Thersandrus compressus live on and eat only Avrainvillea. The gastropod sequesters avrainvilleol from its algal host and uses this compound as an… CONTINUE READING
