Coloration Lastly, humphead wrasse are known to dwell amongst coral beds during the day. Some males grow very large, with one unconfirmed report of a humphead wrasse that was 7.75 ft (2.29 m) long and weighed 420 lbs (190.5 kg). Dentition Indonesia currently allows fishing of the humphead wrasse for research, mariculture, and limited artisanal fishing. 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. A humphead wrasse lying on its side at a cleaning station. Settlement, growth, and persistence of humphead wrasse were highest in branching coral structur es mixed with There are two black lines behind the eyes. Why is the humphead wrasse endangered and what is being done to protect it ? These fish have extremely long life since they are known for living  for at least 30 years and it takes them about five to seven years to reach sexual maturity, which means they are too slow to increase populations. 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. Humphead Maori Wrasse is found throughout the tropical Indo-Pacific, from the Red Sea and the coast of east Africa, to the central Pacific; south from Japan to New Caledonia and the Tuamoto Islands, north to the Ryukyu Islands (Sadovy et al. adult humphead wrasses are mostly found on coral reef slopes, channel slopes, and lagoon reefs in the water, living as deep as three to three hundred feet. The male grows up to two meters, while the female is visibly smaller with an average size of one meter. The pharyngeal teeth, a second set of dentition located inside the fish’s throat, enable the fish to crush prey items. Here, the humphead wrasse lives. Prey items comprising the humpback wrasse’s diet include mollusks, sea urchins, crustaceans, and fishes. They are generally good for reef aquariums, often eating small crustaceans. Although historically fished commercially in northern Australia, Humphead Maori Wrasse have been protected under State legislation in Western Australia since 1998, and in Queensland since 2003. In the larger males, the hump on the head becomes more prominent and takes on a brilliant blue coloration. Adults are generally lonely and spend the day wandering the reef and then return to particular caves or shelves, where they rest during the night. 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. There are many variations within the family. The females, both young and old, are red or orange at the top of their bodies, and from red-orange to white below. Knife fish are elongated and laterally compressed, while members of Cheilinus, Choerodon, and many Bodianus are large and robust. However, today it is forbidden to feed the Napoleon fish with eggs, due to the high level of cholesterol found in dead specimens in the area. The youngest specimens’ body color varies from bright yellow and orange to dull gray and brown, and some have camouflage patterns. Many species of this family are considered as collectible species because of the colors of their scales, being one of the favorites to find by divers in many regions of the world. Let’s start mentioning the River labridae which can be fishivores, zooplanctívores, molluscs, herbivores,  polyquette predators, decapod crab predators and coral predators, as well as many others.

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. Fishes in the Fresh Waters of Florida Gallery, Check the status of the humphead wrasse at the IUCN website. The coral islands of the Tuamotu archipelago, with its 78 atolls, provide a unique habitat for a variety of coral fish. Therefore, the lifecycle continues, beginning with the combination of the gametes followed by mitosis in the gametic lifecycle. and on deeper reef flats. In 2003, Australia prohibited the take and possession of this species other than for some educational uses and public display. 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. Food Habits 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. As in parrotfish, some advance through «phases», and each phase corresponds to a change in morphology (shape and color). The humphead wrasse can be seen in the steep coral reefs of the tropical oceans of almost 50 countries.

The humphead wrasse has large, plump lips that make this fish the perfect creature to control the growth of toxic and spiny reef creatures. In particular, these aggregations form daily after high tide at certain locations along the seaward edge of the barrier reef off Palau. Eating this fish has resulted in cases of ciguatera poisoning. It is also known to feed on sharp-fanged moray eels.Reproduction Additionally, if wrasse are going to be taken out of their natural habitat to be put in these programs, it is also essential that protection is put into place for coral reefs that they would normally inhabit. Unsustainable consumption of live reef fish deprives them of their natural resources and potential food, and also eliminates key species from the marine ecosystem. Nowadays, many reef fish are captured faster than they can naturally recover, which results in the continuous decline of their population. They can live for 30 years, grow to 2 meters in length, and weigh as much as a motorcycle. After the offspring are hatched in the epipelagic zone, the larvae bid their time and float until they become large enough to swim down to a coral reef environment. habitat and more…, Ghost-Crystal Shrimps: Everything you should know about them. Many species are buried in the sand often agitating the  gravel. As their numbers decrease, the rarity of the species is likely to condition an even greater increase in prices. Spawning occurs at certain times of the year with adults forming spawning aggregations at the down-current end of the reef. Size, Age, and Growth For coral-reef ecosystems, this fish is also in hot demand. This is because humphead wrasse are the primary predators of the crown of thorns starfish. Finally, as suggested by their various eating habits, they perform many important ecological functions for the reefs tropical regions’ reefs and temperate regions around the world. The species in coral reefs are intimately linked through the food chain and many of these chains intersect to form a food web. Fisheries. It is the largest member of the Labridae family. the humphead wrasse and the coralgrouper appeared to utilize specific nursery habitats. Its colors, large size and shape have led to consider it as the most striking of the labridae family, which is characterized by the amazing color of its members. Divers who observe a school of humphead wrasses feeing on a reef have been known to hear the noise and see the clouds of dust from the demolition of hard corals by this species. The humphead wrasse is among the most prized species in the lucrative trade of reef fish. The colors of this species vary with age and sex. Individuals form small to medium-sized spawning aggregations, usually on outer reefs. The humphead wrasse was originally described as Cheilinus undulatus by Rüppell in 1835. This is a practice that destroys coral reefs. Additionally it has a bright reddish red area on the head and fine orange lines that radiate from the eyes. Juvenile inhabits coral-rich areas of lagoon reefs where staghorn, or Acropora, corals abound. In Fiji, annual catch decreased by more than 80%, with catch rates of 2-5 large fish per month in the 1970s and 1980s declining to just 1 per month in 2003. I believe that this has caused them to adapt to eating crown of thorns starfish which feed on the coral. Young specimens can be identified by their pale greenish color and two black lines that run behind the eye. Make the population of species decrease. Comment The  fertilization process  begins when the male points his anal fin down and folds the tail and dorsal fins, on its back against the body, while hovering just above the ocean floor .
