Biochemical warfare on the reef comments: 0
 
These outwardly innocuous corals, commonly known as gorgonians, have a few tricks up their soft sleeves. They have evolved a powerful arsenal of chemical toxins that leave all who dare to consume them with a mouthful of distasteful compounds and a lesson they won’t soon forget.
 
 
The gorgonians’ chemical defences do an excellent job of deterring most fishes and other large predators. But the marine snail called Cyphoma gibbosum has learned how to navigate the gorgonians’ toxic chemical mine-field and exploit these abundant corals for both food and shelter, giving themselves an edge over their fellow reef competitors. This predator inflicts damage to more gorgonian colonies per year than even the most destructive hurricane.
