Corals call for fish aid when attacked by Seaweed

Corals in the genus Acropora generate much of the structural complexity upon which coral reefs depend, but they are susceptible to damage from toxic seaweeds. Acropora nasuta minimises this damage by chemically calling goby fishes who within minutes start chomping on the seaweed.
