Conspicuous coloration is a method used by some cleaner fish, where they often display a brilliant blue stripe that spans the length of the body. Other species of fish, called mimics, imitate the behavior and phenotype of cleaner fish to gain access to client fish tissue.
It is not known whether the false cleanerfish adopts a permanent color pattern or if it alters its coloration to mimic the appearance of neighboring cleaner wrasses. One major difference in appearance between the false cleanerfish and its model is the location of the mouth.
Animal coloration. A brilliantly-coloured oriental sweetlips fish ( Plectorhinchus vittatus) waits while two boldly-patterned cleaner wrasse ( Labroides dimidiatus) pick parasites from its skin. The spotted tail and fin pattern of the sweetlips signals sexual maturity; the behaviour and pattern of the cleaner fish signal their availability for ...
Though Thalassoma bifasciatum is a common cleaner fish in the coral reefs they inhabit, they avoid cleaning piscivores such as the spotted moray, the graysby, and the red hind. Such species will view them as prey, but will not view gobies, another kind of cleaner fish, as prey.
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.
Fish coloration, a subset of animal coloration, is extremely diverse. Fish across all taxa vary greatly in their coloration through special mechanisms, mainly pigment cells called chromatophores. Fish can have any colors of the visual spectrum on their skin, evolutionarily derived for many reasons.
The best known cleaning symbioses are among marine fishes, where several species of small fish, notably of wrasse, are specialised in colour, pattern and behaviour as cleaners, providing a cleaning and ectoparasite removal service to larger, often predatory fish.
Bluestreak cleaner wrasses clean to consume ectoparasites on client fish for food. The bigger fish recognise them as cleaner fish because they have a lateral stripe along the length of their bodies, [9] and by their movement patterns.
Labroides bicolor is a species of wrasse endemic to the Indian Ocean and the Pacific Ocean. It is known by various names including bicolor cleanerfish, bicolor (ed) cleaner wrasse, cleaner wrasse, two-color cleaner wrasse and yellow diesel wrasse .
Their habitat on coral reefs, considered “cleaning stations”, which combined with the bright blue coloration on parts of their head allows the species to attract clients and feed off of the removed ectoparasites.
