Reef for about a quarter of marine organisms provide habitat and nutrition, but they have to face from the conch to starfish and many other natural predators. But fortunately, for living in the Indian Ocean – Pacific Ocean staghorn coral, the coral defend crab can save them.

This is just a 4 mm wide crustaceans will settle on the reef (as shown), and fiercely defend their host, in exchange for food and shelter. In order to study different species of coral crab defend and sizes on its defense capability, the researchers removed in 2008 near the French Polynesian coral Morley Kea 45 “colonies” in the largest number of species – macular trapezoid crab (Trapezia flavopunctata), and the duration of two weeks.

At that time, the trash can lid sized starfish populations to flourish, it is possible to completely destroy these corals. However, macular trapezoid crabs live coral remains intact, but those without this creature coral, even stranger with other crabs, are still being eaten by these starfish overnight. Researchers recently published online in the relevant conclusions PeerJ.

In addition, other studies have found that the smallest crab is a skilled defense conch, crab and medium in size from bread to protect coral starfish violations.
