The wrasses are a family, Labridae, of marine fish, many of which are brightly colored. The family is large and diverse, with over 600 species in 81 genera, which are divided into 9 subgroups or tribes. They are typically small, most of them less than 20 cm (7.9 in) long, although the largest, the humphead wrasse, can measure up to 2.5 m (8.2 ft). They are efficient carnivores, feeding on a wide range of small invertebrates. Many smaller wrasses follow the feeding trails of larger fish, picking up invertebrates disturbed by their passing. Juveniles of some representatives of the genera Bodianus, Epibulus, Cirrhilabrus, Oxycheilinus, and Paracheilinus hide among the tentacles of the free-living mushroom corals and Heliofungia actiniformis.
The false cleanerfish is a species of combtooth blenny, a mimic that copies both the dance and appearance of Labroides dimidiatus, a similarly colored species of cleaner wrasse. It likely mimics that species to avoid predation, as well as to occasionally bite the fins of its victims rather than consume parasites. Most veiled attacks occur on juvenile fish, as adults that have been attacked in the past may avoid or even attack A. taeniatus.
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).
Stenopus hispidus is a shrimp-like decapod crustacean belonging to the infraorder Stenopodidea. Common names include coral banded shrimp and banded cleaner shrimp.
The spotted cleaner shrimp, is a kind of cleaner shrimp common to the Caribbean Sea. These shrimp live among the tentacles of several species of sea anemones. They sway their body and wave their antennae in order to attract fish from which they eat dead tissue, algae and parasites.
A cleaning station is a location where aquatic life congregate to be cleaned by smaller beings. Such stations exist in both freshwater and marine environments, and are used by animals including fish, sea turtles and hippos.
Cheating is a term used in behavioral ecology and ethology to describe behavior whereby organisms receive a benefit at the cost of other organisms. Cheating is common in many mutualistic and altruistic relationships. A cheater is an individual who does not cooperate but can potentially gain the benefit from others cooperating. Cheaters are also those who selfishly use common resources to maximize their individual fitness at the expense of a group. Natural selection favors cheating, but there are mechanisms to regulate it. The stress gradient hypothesis states that facilitation, cooperation or mutualism should be more common in stressful environments, while cheating, competition or parasitism are common in benign environments.
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.
Cleaner fish are fish that show a specialist feeding strategy by providing a service to other species, referred to as clients, by removing dead skin, ectoparasites, and infected tissue from the surface or gill chambers. This example of cleaning symbiosis represents mutualism and cooperation behaviour, an ecological interaction that benefits both parties involved. However, the cleaner fish may consume mucus or tissue, thus creating a form of parasitism called cheating. The client animals are typically fish of a different species, but can also be aquatic reptiles, mammals, or octopuses. A wide variety of fish including wrasse, cichlids, catfish, pipefish, lumpsuckers, and gobies display cleaning behaviors across the globe in fresh, brackish, and marine waters but specifically concentrated in the tropics due to high parasite density. Similar behaviour is found in other groups of animals, such as cleaner shrimps.
Acanthurus coeruleus is a species of marine ray-finned fish belonging to the family Acanthuridae, the surgeonfishes, unicornfishes and tangs, found in the Atlantic Ocean. It can grow up to 39 centimetres (15 in) long. Common names include Atlantic blue tang, blue barber, blue doctor, blue doctorfish, blue tang, blue tang surgeonfish, yellow barber, and yellow doctorfish.
The bluestreak cleaner wrasse is one of several species of cleaner wrasses found on coral reefs from Eastern Africa and the Red Sea to French Polynesia. Like other cleaner wrasses, it eats parasites and dead tissue off larger fishes' skin in a mutualistic relationship that provides food and protection for the wrasse, and considerable health benefits for the other fishes.
Ancylomenes magnificus, also known as the magnificent anemone shrimp, is a species of cleaner shrimp common to the Western Pacific Ocean at depths of 3–29 metres (10–95 ft). They are commonly found on stony coral, Catalaphyllia and the sea anemone, Dofleinia armata.
Lysmata is a genus of shrimp in the infraorder Caridea, the caridean shrimp. The genus belongs to the family Lysmatidae. Lysmata are popular ornamental shrimp in the marine aquarium trade for their bright color patterns, interesting behaviors, and ability to control certain aquarium pests such as sea anemones of the genus Aiptasia. They are known to command high prices on the pet market.
Lysmata vittata, commonly known as the peppermint shrimp, is a species of shrimp, native to the Indo-Pacific from East Africa to the Philippines, Japan, Australia and New Zealand.
Urocaridella antonbruunii, common names clear cleaner shrimp or red-white cleaner shrimp, is a species of shrimp belonging to the family Palaemonidae. It was described by A. J. Bruce in 1967. It is one of the species that are known as cleaner shrimps.
Cleaning symbiosis is a mutually beneficial association between individuals of two species, where one removes and eats parasites and other materials from the surface of the other. Cleaning symbiosis is well-known among marine fish, where some small species of cleaner fish, notably wrasses but also species in other genera, are specialised to feed almost exclusively by cleaning larger fish and other marine animals. Other cleaning symbioses exist between birds and mammals, and in other groups.
Ancylomenes pedersoni, sometimes known as Pederson's shrimp and Pederson's cleaner 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.
The Hawaiian cleaner wrasse or golden cleaner wrasse, is a species of wrasse found in the waters surrounding the Hawaiian Islands. The fish is endemic to Hawaii. These cleaner fish inhabit coral reefs, setting up a territory referred to as a cleaning station. They obtain a diet of small crustacean parasites by removing them from other reef fish in a cleaning symbiosis.
Lysmata grabhami is a species of saltwater shrimp in the family Hippolytidae. It was first described by Gordon in 1935. It occurs in the tropical and subtropical Atlantic Ocean and is a cleaner shrimp, operating a cleaning station to which fish come to have parasites removed.
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.
