(Labre masqu?)

Overview

[ Back to top ]

Family : Wrasses ; Inhabits semi-exposed reef flats and lagoon and seaward reefs[1]. Common in areas of mixed sand , and rubble that are subject to mild surge[1]. Juveniles shallow on rubble amongst large bommies or protected open patches on reef crests and swim as if were a leaf floating along the bottom ; large adults move along over large reef section, usually in pairs and typically turn or shift large pieces of rubble or debris that they grab and pull with their mouth or push over with their snout. Often, while one works the piece, the other grabs exposed prey . They are sometimes called rock-mover wrasse, but they don't move real rocks[2]. Highly territorial [3]. Feeds on mollusks, sea urchins, brittle stars, polychaetes , and crabs[4]; feeding is done by overturning large rocks to expose target preys. The young imitate drifting masses of algae[5]. Marketed fresh[6]. Minimum depth reported from Ref. 30874.

Description

Physical Description

Species Novaculichthys taeniourus

Rockmover wrasses , also called dragon wrasses, have an oblong compressed body and a wedge-shaped head . Except for two scales on the upper part of the gill coverings and an almost vertical row of small scales behind each eye. their head is scaleless . In juveniles the first two dorsal fin spines are long and extended, drooping over the fish's forehead to form a "cowlick". As the fish mature , the elongated rays are lost.

Adult fish have a dark greenish-brown body with an elongated white spot on each scale. Their head is a gray-blue with brown lines radiated from their eyes. There are two black spots in front of the dorsal fin and a wide vertical white bar on base of the caudal fin. The posterior part of their caudal fin and pelvic fins are black. Juveniles found in Hawaii are usually green and those in the western Pacific are burgundy to brownish. Both are spotted in white.

Rockmover wrasses are 27-30 cm (10.6-12 in) in length .

Habitat

Adult fish live on shallow semi-exposed reef flats and in lagoons and seaward reefs to depths of 14-25 m (46-82 ft ). They prefer hard-bottomed grassy areas of mixed sand and rubble where there is exposure to a mild surge. Juveniles favor shallow areas on rubble among large patch reefs or protected open patches on reef crests .

Typically found in water with a depth of 0 to -5,227 meters (0 to -17,149 feet).[7]

Ecology: This species is found in sandy and rubble areas among coral reefs, including semi-exposed reef flats , lagoons and seaward reefs. It often occurs over areas of mixed sand and rubble subject to mild surge (Myers 1991). Juveniles are found over shallow rubble amongst large bommies or protected open patches on reef crests . Larger adults are often found in pairs over rubble areas, where they move pieces of coral debris with their mouths to search for food.

This species feeds on zoobenthos , including molluscs , echinoderms , polychaetes and crabs (Fischer et al. 1990). The juveniles, which imitate floating leaves or algal fronds, are quite different in their form and colour pattern to the adults, which are highly territorial (Westneat 2001).[8].

Biology

Diet

Rockmover wrasses are opportunistic , feeding on a wide variety of bottom dwelling animals usually hidden under rocks, such as worms, snails, crabs, and brittle stars. Both juvenile and adult rockmover wrasses overturn rocks and rubble to expose target prey , a behavior that is the source of their common name .

Reproduction

Although little is known about reproduction of these fish, it is believed that, like other wrasses , they probably are able to change sex and are pelagic spawners, broadcasting eggs and sperm into the water column .

Behavior

These fish are highly territorial . Large adults , usually in pairs, move over “their” large section of a reef. One fish turns or shifts large pieces of debris or rubble grabbing or pulling it with its mouth or pushing it with its snout. When the working member of the pair has revealed the prey , the other fish quickly grabs and eats it. Juveniles do not usually work in pairs, doing all the work themselves.

Facing danger, these wrasses quickly dive into the sand for protection. Juveniles resemble algae and mimic the movements of detached, drifting seaweed by swaying back and forth in the currents .

apanese researchers observed rockmover wrasses using coral fragments for mound construction. The wrasses heaped 4-70 pieces of fragments on each sand mount, diving into the mount just before sunset. It appeared that they returned to their own mount repeatedly.
