Scientific Details

Meristics.
Dorsal fin spines/rays: IX, 11
Anal fin spines/rays: III, 10
Caudal fin rays: 12
Pectoral fin rays: 14
Ventral fin spines/rays: I, 5
Lateral line: 24-26

Interpreting fin count meristics.
Spines are in Roman numerals and soft rays are in Arabic numerals. Spines and rays that are continuous in one fin are separated by a comma. Fin sections are separated by semicolons.

Detailed descriptions of fin count and other meristics are in:

Order level detail.
A large and highly diverse group of modern bony fishes many of which have a generalized perch like body form. Most have pelvic fins with one spine and 5 rays and the maxillary bone is excluded from the gape of the mouth. Interrelationships of the group are poorly understood and continue to be studied. They inhabit almost all aquatic habitats from high-altitude strams to the deep sea, although most are marine.

Family level detail.
Usually long, slender colourful fishes with a single long-based dorsal fin, well-developed pectoral fins used for swimming, thick lips, jaws with well-developed canine teeth and crushing molars on the bones at the bases of the gill arches. Many are protogynous hermaphrodites, meaning that they change sex from female to male.

Recent molecular studies indicate the Labridae is not a natural group without the inclusion of the Weed whitings (formerly Odacidae) and Parrotfishes (formerly Scaridae).

General Description

Moderately deep-bodied wrasses. Adults overall greenish-blue to brown, with a purple tinge, and five indistinct yellowish bars on body and fins. Juveniles reddish-brown with green and orange mottling. To 45 cm.

Biology

These fishes are carnivores with strong canines and crushing teeth for feeding on benthic invertebrates such as crabs, bivalve and gastropod molluscs and echinoderms. Juveniles prey on tiny amphipod and isopod crustaceans.

Habitat
