Cleaning symbiosis is a mutually beneficial association between individuals of two species, where one (the cleaner) removes and eats parasites and other materials from the surface of the other (the client). Cleaning symbiosis is well-known among marine fish, where some small species of cleaner fish, notably wrasses but also species in other ...
Aquaculture of sea sponges. Sea sponge aquaculture is the process of farming sea sponges under controlled conditions. It has been conducted in the world's oceans for centuries using a number of aquaculture techniques. There are many factors such as light, salinity, pH, dissolved oxygen and the accumulation of waste products that influence the ...
Since ambient currents are faster at the top, the suction effect that they produce by Bernoulli's principle does some of the work for free. Sponges can control the water flow by various combinations of wholly or partially closing the osculum and ostia (the intake pores) and varying the beat of the flagella, and may shut it down if there is a ...
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 ...
A) A superhydrophobic surface with a high contact angle nearing 180 degrees. B) A surface with a low water sliding angle. C) A surface with a higher sliding angle which will be less efficient when self-cleaning water from its surface. Control over surface wettability is a critical aspect of self-cleaning surfaces.
In fluid dynamics, an eddy is the swirling of a fluid and the reverse current created when the fluid is in a turbulent flow regime. [2] The moving fluid creates a space devoid of downstream-flowing fluid on the downstream side of the object. Fluid behind the obstacle flows into the void creating a swirl of fluid on each edge of the obstacle ...

Crimson cleaner fish. The crimson cleaner fish ( Suezichthys aylingi ), or butcher's dick in Australia, [2] is a species of wrasse native to the southwestern Pacific Ocean around Australia and New Zealand. This species inhabits patches of sand on reefs at depths of from 6 to 100 metres (20 to 328 ft). It is a cleaner fish.
