The Slingjaw Wrasse (Epibulus insidiator) is… insidious!

These fish can reach up to 50 cm long… but that doesn’t include their monster-mouth!

They swim around coral reefs, anywhere from east Africa to Hawaii, peering into rocky crevices and coral branches as they search for crustaceans and small fish to prey on.

When they find something, they shoot their mouth out until it’s a tube up to half as long as their body. With this they can ambush prey or vacuum them out of nooks and crannies.
