The wrasse's genomes must be analyzed to help keep the species alive. Adults are more common offshore than inshore, their preferred habitat being steep outer reef slopes, reef drop-offs, passes and tops, channel slopes, and lagoon reefs to at least 100 m. They are typically found in association with well-developed coral reefs and may be somewhat sedentary; the same individuals may be seen along the same stretch of reef for extended periods. Being so large, the humphead wrasse has few natural predators. This protrusion becomes more noticeable as … The wrasse is invaluable not when it's on people's dinner plates — but when it's simply left alone in the clear ocean waters it inhabits.

Juveniles occur in coral-rich areas of lagoon reefs, particularly among live thickets of staghorn Acropora sp. It appears to be one of the few predators of toxic animals such as the crown of thorns starfish, boxfishes and sea hares. Like many members of the wrasse family, it rarely moves its tail for locomotion but rather flaps its pectoral fins to swim. The color of the juvenile is more muted. Unfortunately this makes them a prime target as a luxury food and illegal trapping. Juveniles are usually found in shallow, sandy ranges bordering coral reef waters, while adults are found mostly in offshore and deeper areas of coral reefs, typically in outer-reef slopes and channels, but also in lagoons. Here are 4 facts you didn’t know about the bumphead parrotfish. The newly-hatched humphead larvae drift with the current, where they feed on algae until they can seek refuge in the shallows, preferring mangrove forest root systems and seagrass lagoons where they feed primarily on seaweed for up to 3 years before joining the adults in the reefs.

The longevity of the species, however, and our limited knowledge of reef fish biology, in general, suggest that adult mortality is low. "Complete mitochondrial genome sequence of the humphead wrasse.
