Hypoplectrus is a genus of fishes commonly known as hamlets, found mainly in coral reefs in the Caribbean Sea and the Gulf of Mexico, particularly around Florida and the Bahamas. They are a popular choice for hobbyist saltwater aquariums, and come in a variety of colors.

Species

There are currently 17 recognized species in this genus:

Reproduction

Hamlets are simultaneous hermaphrodites (or synchronous hermaphrodites): They have both male and female sexual organs at the same time as an adult, meaning that they function as a male and female, making them one of the few vertebrates that are male and female at the same time. They seem quite at ease mating in front of divers, allowing observations in the wild to occur readily. They do not practice self-fertilization, but when they find a mate, the pair takes turns between which one acts as the male and which acts as the female through multiple matings, usually over the course of several nights. Hamlets preferentially mate with individuals of their same color pattern. [3]

<span class="mw-page-title-main">Serranidae</span> Family of fishes

The Serranidae are a large family of fishes belonging to the order Perciformes. The family contains about 450 species in 65 genera, including the sea basses and the groupers. Although many species are small, in some cases less than 10 cm (3.9 in), the giant grouper is one of the largest bony fishes in the world, growing to 2.7 m in length and 400 kg (880 lb) in weight. Representatives of this group live in tropical and subtropical seas worldwide.

<span class="mw-page-title-main">Grouper</span> Subfamily of fishes

Groupers are fish of any of a number of genera in the subfamily Epinephelinae of the family Serranidae, in the order Perciformes.

<span class="mw-page-title-main">Tilefish</span> Family of fishes

Tilefishes are mostly small perciform marine fish comprising the family Malacanthidae. They are usually found in sandy areas, especially near coral reefs.

<span class="mw-page-title-main">Anthiinae</span> Subfamily of fishes

Anthias are members of the family Serranidae and make up the subfamily Anthiinae. Anthias make up a sizeable portion of the population of pink, orange, and yellow reef fishes seen swarming in most coral reef photography and film. The name Anthiidae is preoccupied by a subfamily of ground beetles in the family Carabidae created by Bonelli in 1813 and this grouping should be called the Anthiadinae. However, both the 5th Edition of Fishes of the World and Fishbase give the Serranid subfamily as "Anthiinae".

<span class="mw-page-title-main">Haemulidae</span> Family of fishes

Haemulidae is a family of fishes in the order Perciformes known commonly as grunts. It is made up of the two subfamilies Haemulinae (grunters) and Plectorhynchinae (sweetlips), which in turn contain about 133 species in 19 genera. These fish are found in tropical fresh, brackish, and salt waters around the world. They are bottom-feeding predators, and named for the ability of Haemulinae to produce sound by grinding their teeth. They also engage in mutualistic relationship with cleaner gobies of genus Elacatinus, allowing them to feed on ectoparasites on their bodies.

<span class="mw-page-title-main">Masked hamlet</span> Species of fish

The masked hamlet is a species of marine ray-finned fish, a sea bass from the subfamily Serraninae which is part of the family Serranidae, which also includes the groupers and anthias. This species is found in the western Atlantic Ocean in the Caribbean Sea and has been recorded from the coast of Central America from Quintana Roo in Mexico to Bocas del Toro in Panama and from Jamaica to Puerto Rico, as well as in the Turks and Caicos and the Cayman Islands. Its specific name refers to Providencia Island, Colombia where the type was collected. It was also recorded from other islands in the Archipelago of San Andrés, Providencia and Santa Catalina. They are a unique species in the Hypoplectrus genus, defined by their unique color morph. Their behavior is largely similar to that of other hamlets, especially in their diet and egg-trading spawning patterns.

<i>Serranus</i> Genus of fishes

Serranus is a genus of fish in the family Serranidae. It is one of five genera known commonly as the "Atlantic dwarf sea basses". These fish are hermaphrodites, each individual possessing functional male and female reproductive tissues. When a pair spawns, one fish acts as a male and the other acts as a female.

<i>Caranx lugubris</i> Species of fish

Caranx lugubris, the black jack, black trevally, black kingfish, coal fish or black ulua, is a species of large ocean fish in the jack family Carangidae. The species has a circumtropical distribution, found in oceanic, offshore waters of the tropical zones of the Pacific, Atlantic and Indian Oceans. The species is particularly prevalent around offshore islands such as the Caribbean islands in the Atlantic, Hawaii and French Polynesia in the Pacific and the Seychelles and Maldives in the Indian Ocean. Black jack are rare in shallow waters, preferring deep reefs, ledges and seamounts in clear waters. The species is easily distinguished by its black to grey fins and jet black scutes, with the head having a steep profile near the snout. The largest recorded length is 1 m and weight of 17.9 kg. The black jack lives either individually or in small schools, and is known to school with other species. It is a predatory fish, taking a variety of fish, crustaceans and molluscs as prey. Sexual maturity is reached at 34.6 cm in females and 38.2 cm in males, with spawning taking place between February and September in the Caribbean. The early life history of the species is very poorly understood. Black jack are of high importance to many island fisheries, but are rarely encountered in most continental fisheries. The species has a reputation as a gamefish, and is variably considered a terrible or excellent food fish, although several cases of ciguatera poisoning have been attributed to the species. The species was initially named Caranx ascensionis by Georges Cuvier, however several issues with the use of this name have seen Felipe Poey's name Caranx lugubris become the valid scientific name.

<i>Lutjanus</i> Genus of fishes

Lutjanus is a genus of marine ray-finned fish, snappers belonging to the family Lutjanidae. They are found in the Atlantic, Indian, and Pacific Oceans.
