Lysmata is a genus of shrimp in the infraorder Caridea, the caridean shrimp. The genus belongs to the family Lysmatidae. [3] Lysmata are popular ornamental shrimp in the marine aquarium trade for their bright color patterns, interesting behaviors, and ability to control certain aquarium pests [3] such as sea anemones of the genus Aiptasia . [4] They are known to command high prices on the pet market. [5]
The genus is informally divided into two main categories. Some species are cleaner shrimp which "clean" parasites and other material from fish, live in pairs, and are brightly colored, often in contrasting reds and yellows with white antennae. Other species are the "peppermint shrimp", which have semi-translucent, red-banded bodies, and live in large groups. Some peppermint shrimp perform cleaning behaviors, but less actively than do the cleaner shrimp. [4]
The genus has been studied with interest due to its unusual sexual system, protandric simultaneous hermaphroditism. [3] While some other taxa of shrimp undergo sequential hermaphroditism, they have only been observed changing from male to female. In Lysmata, males become true hermaphrodites instead of females. [6] So far, every species studied has been confirmed to have this sexual system. [7] During their "female phase" they actually have functioning male and female tissues in their gonads and produce both types of gamete. When paired, they take turns fertilizing each other's eggs. [6]
Lysmata occur in the tropics and in warmer temperate waters. They usually live on rock and coral reefs, in shallow and deeper areas. Some live in sponges. [7]
Lysmata contains the following species: [8]
The Caridea, commonly known as caridean shrimp or true shrimp, are an infraorder of shrimp within the order Decapoda. This infraorder contain all species of true shrimp. They are found widely around the world in both fresh and salt water. Many other animals with similar names – such as ghost shrimps, mud shrimps, and boxer shrimps – are not true shrimps, but many have evolved features similar to true shrimps.
Lysmata amboinensis is an omnivorous shrimp species known by several common names including the Pacific cleaner shrimp. It is considered a cleaner shrimp as eating parasites and dead tissue from fish makes up a large part of its diet. The species is a natural part of the coral reef ecosystem and is widespread across the tropics typically living at depths of 5–40 metres (16–131 ft).
Hippolytidae is a family of cleaner shrimp, also known as broken-back shrimp or anemone shrimp. The term "broken-back shrimp" also applies to the genus Hippolyte in particular and "cleaner shrimp" is sometimes applied exclusively to Lysmata amboinensis.
Alpheidae is a family of caridean snapping shrimp, characterized by having asymmetrical claws, the larger of which is typically capable of producing a loud snapping sound. Other common names for animals in the group are pistol shrimp or alpheid shrimp.
Lysmata debelius is a species of cleaner shrimp indigenous to the Indo-Pacific. It is popular in the aquarium trade, where it is known as the fire shrimp, blood shrimp or scarlet cleaner shrimp.
Alpheopsis is a genus of shrimp of the family Alpheidae. Several species of the genus have been known to share the same burrows with members of different species. They are inhabitants of the Eastern Pacific Ocean.
Athanas is a genus of shrimp of the family Alpheidae. These are small shrimp measuring 2 cm in length. Females have smaller chelae than males.
Synalpheus is a genus of snapping shrimp of the family Alpheidae, presently containing more than 100 species; new ones are described on a regular basis, and the exact number even of described species is disputed.
Rhynchocinetes is a genus of shrimp, containing the following 14 species:
Lysmata vittata, the peppermint shrimp, is a species of shrimp, native to the Indo-Pacific from East Africa to the Philippines, Japan, Australia and New Zealand.
Birulia is a genus of shrimp. It is one of a group of genera that are usually treated as part of the family Hippolytidae, but have also been separated off as the family Thoridae.
Ancylomenes pedersoni, sometimes known as Pederson's shrimp, is a species of cleaner shrimp. It is part of the genus Ancylomenes and was described in 1958 by Fenner A. Chace Jr. as Periclimenes pedersoni. Ancylomenes pedersoni is found in the Caribbean Sea, often associated with a sea anemone, at depths of 1 to 15 metres. They are often found on the reefs off Bermuda.
Lysmata boggessi is a species of saltwater shrimp first classified as Lysmata wurdemanni. It is found in shallow waters of the Atlantic Ocean, and can be distinguished by its coloration pattern.
Lysmata bahia is a species of saltwater shrimp first classified as Lysmata wurdemanni. It is found in shallow waters of the Atlantic Ocean, and can be distinguished by its coloration pattern.
Lysmata pederseni is a species of saltwater shrimp first classified as Lysmata wurdemanni. It is found in shallow waters of the Atlantic Ocean, and can be distinguished by its coloration pattern and its association with tube sponges.
Lysmata ankeri is a species of saltwater shrimp first classified as Lysmata wurdemanni. It is found in shallow waters of the Atlantic Ocean, and can be distinguished by its coloration pattern.
Thoridae is a family of cleaner shrimp, also known as broken-back shrimp or anemone shrimp.
Parhippolyte is a genus of cave dwelling decapod crustaceans, known as cave shrimps from the family Barbouriidae The type species Parhipplyte uvea was described in 1900 by the English carcinologist Lancelot Alexander Borradaile from specimens collected in the south western Pacific by Arthur Willey. As their vernacular name of cave shrimp suggests these species are generally found in marine caves as well as anchialine ponds and lagoons.
Periclimenes, commonly known as glass shrimp or cleaner shrimp, is a commensal and often symbiotic genus of semi-transparent shrimp within the family Palaemonidae. Species of this large genus feature a wide variety of coloration and patterns, widespread distribution throughout much of the world's tropical oceans, and are often sought out for aquarium trade.
Processa edulis is a species of caridean shrimp found in shallow water in the Atlantic Ocean and the Mediterranean Sea. It mostly inhabits seagrass beds and eelgrass flats, hiding by day and feeding at night. A common name for it is nika shrimp.
