They can live for 30 years, grow to 2 meters in length, and weigh as much as a motorcycle. This is a practice that destroys coral reefs. The maximum reported length of the humphead wrasse is 90 inches (229 cm) total length (TL), however it is more commonly observed at lengths of 24 inches (60.0 cm) TL. They move in shallow bays during the day to feed, and tend to move into deeper waters as they grow and get bigger. Females rarely exceed about 3 feet (1 m) in length. These large, colorful reef fish have been reported up to 7 feet, but normally average about 2 feet long. In 2003, Australia prohibited the take and possession of this species other than for some educational uses and public display. Spawning in this location has been documented for most months of the year and probably occurs throughout the year with some seasonal and lunar variation possible. Therefore, the lifecycle continues, beginning with the combination of the gametes followed by mitosis in the gametic lifecycle. Juveniles select branching hard and soft corals and seagrass beds at settlement. There are stories of two fish of the same species that look so different that they had originally been scientifically described as two separate species. Males of this species can reach 50 cm in total length. In the larger males, the hump on the head becomes more prominent and takes on a brilliant blue coloration. Pairs spawn together as a part of the aggregation which may number up to 100 individuals.

In particular, these aggregations form daily after high tide at certain locations along the seaward edge of the barrier reef off Palau. Males of this species can reach 45 cm in total length. The U.S. National Marine Fisheries Service considers it a species of concern although it is data deficient to be listed under the Endangered Species Act. The depletion of reef fishery resources could be a huge challenge for the food stability and livelihood of these people. Wrasse Facts Wrasse is marine fish that belongs to the Labridae family. The females then rise up as the male swims past, releasing gametes for fertilization near the water’s surface .

Other countries including the Philippines, Maldives, and Palau have enacted some protective regulations as well. The humphead wrasse has large, plump lips that make this fish the perfect creature to control the growth of toxic and spiny reef creatures. Juvenile inhabits coral-rich areas of lagoon reefs where staghorn, or Acropora, corals abound. That’s partially because of how slowly it breeds. The humphead wrasse resides in the Indo-Pacific region from the Red Sea to South Africa and to the Tuamoto Islands, north to the Ryukyu Islands, and south to New Caledonia. There are many variations within the family. In response to declining populations of the humphead wrasse, some countries have began to take action. Trade restrictions are particularly important since this species cannot be bred in captivity, and all people who have seen specimens in restaurants and fish markets should know that they come from nature, and therefore sometimes reveal the violation of regulations existing by the captors. After the fertilization of the eggs, the specifically chosen current takes these eggs to float in the epipelagic zone, or near the surface of the open ocean . Even though the Humphead maori wrasse is widely distributed, all country based reports on this fish have shown severe declines in the wild population, even in its most suitable habitat.

The humphead wrasse feeds on mollusks, reef fish, sea urchins, crustaceans and other invertebrates. Indonesia currently allows fishing of the humphead wrasse for research, mariculture, and limited artisanal fishing. This area spreads from the Red Sea and the East African coast to the central Pacific. The results can provide insights on the roles of habitat availability and of the detectability of juveniles on population size. Adult males develop a black stripe along the sides, with blue spots on their body scales and blue scribbles on the head.

The humphead wrasse, which can grow up to six feet long, is considered a luxury food in parts of Asia. Using mark–recapture techniques, I For coral-reef ecosystems, this fish is also in hot demand. Young specimens can be identified by their pale greenish color and two black lines that run behind the eye. 5. It also covers the waters from South Japan to New Caledonia. Distinctive Features The humphead wrasse is a large species of wrasse mainly found on coral reefs in the Indo-Pacific region. (adsbygoogle = window.adsbygoogle || []).push({}); The humphead wrasse is one of the most striking fish in the Indo-Pacific Ocean. When the females are ready to spawn, they rise up as the posturing male swims past with the pari releasing gametes in a calm manner near the surface. These threats include the live reef food fish trade, spearfishing, destructive fishing techniques (cyanide/dynamite), habitat loss and degredation, marine aquarium trade, and unregulated fisheries. One species, Conniella apterygia, is so small that it lacks even pelvic fins and a supporting skeleton. 2.1 Distribution, habitat and movement. One of the largest reef fishes in the world, the humphead wrasse is made even more imposing by the presence of a prominent hump located on the forehead from which it earns its various common names.

IUCN specialists are currently working on the collection of data on populations and actions aimed at increasing people’s awareness of the need to protect this creature. 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. Why is the humphead wrasse endangered and what is being done to protect it ?

The male grows up to two meters, while the female is visibly smaller with an average size of one meter. They are also one of the few predators of toxic animals such as sea hares, chestfish and the «crown of thorns» starfish , and are therefore an important part of the marine food chain in maintaining a reef balanced and healthy coral.

It is one of the largest reef fish in the world and some specimens can grow up to 2.30 meters, and weigh 190 kilograms.It has full lips and a hump on the head that is similar to a Napoleonic hat, which gives rise to its name and that, becomes more prominent with age. They are protogynous hermaphrodites, so sometimes a female will become a male, and turn from a female’s rusty red-orange colors to a male’s bright blue-green colors. The lips seem to absorb the spines of its prey so that the fish can chew its victim without hurting itself. Planktonic eggs are released into the water, and once the larvae have hatched they are placed on the substrate. Additionally it has a bright reddish red area on the head and fine orange lines that radiate from the eyes. Humphead wrasse spawn in couples in open water then rise quickly to the surface to release the ova and the spermatozoa.Despite their large size, their are fairly timid, often darting into holes to hide..

The humphead wrasse can be found throughout the Indian Ocean, from the Red Sea to South Africa and the Tuamoto Islands. Although this species is long-lived, it has a very low reproductive rate resulting in a decline in numbers due to a number of threats. Size, Age, and Growth The pharyngeal teeth, a second set of dentition located inside the fish’s throat, enable the fish to crush prey items. They live in giant reefs in the Indo-Pacific Ocean. 2003, Figure 1).
