這蝦的學問是 Hyperiella dilatata In one unusual adaptation, the amphipod crustacean Hyperiella dilatata captures the sea butterfly Clione antarctica (a snail without a shell). The sea butterfly is held alive in a sustained forced attachment on the back of the crustacean, and experiments and analysis reveal that the sea butterfly secretes a previously undescribed beta-hydroxyketone that turns away fish that are normally predators of the crustacean. The authors suggest this unique association -- the abduction of one species by another --is unprecedented in the annals of behavioral and chemical ecology.

圖片描述:
Association between the sea butterfly and the amphipod is not accidental. Rather, the amphipod actively abducts the sea butterfly. First the amphipod grasps the sea butterfly (a) , then it throws the butterfly onto its back (b) and secures it there (c) before swimming off. Such an arrangement slows down the amphipod and makes maneuvering more cumbersome.
