ANIMAL SPECIES:Slingjaw Wrasse, Epibulus insidiator (Pallas, 1770)
The common name of the Slingjaw Wrasse refers to the fish's ability to protrude its mouth to capture prey such as crabs, shrimps and small fishes. When protruded the mouth can be up to half the body length. Juvenile Slingjaw Wrasse look different to adults. They are brown with narrow white bars on the body, resembling fishes of the genus Wetmorella. Initial phase Slingjaw Wrasse are uniformly brown or yellow. Terminal phase Slingjaw Wrasse have a white head, with a dark line through the eye extending onto the body. The body is dark with the exception of an orange region below the dorsal fin.
