This is a small tropical fish in the Grouper/Sea Bass/Hamlet family. Adults are 2 to 4 inches in length and most commonly seen around St. Thomas in deeper coral waters. It is rarely seen at shallow depths (15 to 40ft), becoming more common approaching 60 feet and below down to about 220 to 250 feet.
They will hang out as solitary individuals among coral rubble, sandy areas, patch reefs and lower levels of coral banks. Juveniles may hang out together in small groups of up to four fish.
A sloping snout combined with ultra-tough skin makes the Queen Triggerfish the perfect predator of Sea urchins.
Better known as “Old Wife” in the islands, the fish blows pressurized streams of water at an urchin until it tumbles over. Once the urchin’s unprotected underbelly is exposed, the Old Wife digs in with hard, sharp teeth.
Fish are both opportunistic as well as sloppy eaters. Scraps from the urchin meal attract nearby fish. Very quickly the Old Wife has to defend its meal from pirates. A wide, flat body helps with this task by blocking fish intent on raiding lunch.
In the end, everyone gets something, even if it is just a leftover spine to munch on.
