Green coral goby
The green coral goby, Gobiodon histrio, is a member of the family Gobiidae of the order Perciformes. It is native to the Indo-Pacific waters. Its commercial trade name are Blue-spotted coral goby or Broadbarred goby. It is hiding in the wild behind coral structures.
This fish produces a toxin that deters predators. When disturbed, it releases compounds that inhibit the locomotion of other fish. At high enough concentrations, the toxin causes the predator to lose equilibrium and tip over. It takes part in a mutualistic relationship with a species of coral Acropora nasuta. When the coral is damaged by toxic Chlorodesmis algae, it produces a compound that attracts the fish. The fish eat the alga and this enhances their toxicity.
