Cleaner fish. Cleaner fish are fish that show a specialist feeding strategy [1] by providing a service to other species, referred to as clients, [2] by removing dead skin, ectoparasites, and infected tissue from the surface or gill chambers. [2] This example of cleaning symbiosis represents mutualism and cooperation behaviour, [3] an ecological ...

Cleaner wrasses are best known for feeding on dead tissue, scales, and ectoparasites, although they are also known to 'cheat', consuming healthy tissue and mucus, which is energetically costly for the client fish to produce.

Cage trap at Lembeh Strait, Indonesia. A fish trap is a trap used for catching fish and other aquatic animals of value. Fish traps include fishing weirs, cage traps, fish wheels and some fishing net rigs such as fyke nets. [1] The use of traps are culturally almost universal around the world and seem to have been independently invented many times.
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, and by their movement patterns. Cleaner wrasses greet visitors in an effort to secure the food source and cleaning opportunity with the client.
Two bluestreak cleaner wrasse cleaning a potato grouper, Epinephelus tukula. Mimicry of mutualistic species is seen in coral reef fish, where the models, certain cleaner fish, are greatly disadvantaged by the presence of the mimic. Cleaner fish are mutually beneficial to many other species, which allows them to eat their parasites and dead skin ...
The Hawaiian cleaner wrasse or golden cleaner wrasse ( Labroides phthirophagus ), is a species of wrasse ( genus Labroides) 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 ...
Fishing nets have been used widely in the past, including by stone age societies. The oldest known fishing net is the net of Antrea, found with other fishing equipment in the Karelian town of Antrea, Finland, in 1913. The net was made from willow, and dates back to 8300 BC. [1] Recently, fishing net sinkers from 27,000 BC were discovered in ...
The false cleanerfish ( Aspidontus taeniatus) is a species of combtooth blenny, a mimic that copies both the dance and appearance of Labroides dimidiatus (the bluestreak cleaner wrasse), a similarly colored species of cleaner wrasse. It likely mimics that species to avoid predation, [2] as well as to occasionally bite the fins of its victims ...
