Paracanthurus hepatus is a species of Indo-Pacific surgeonfish.A popular fish in marine aquaria, it is the only member of the genus Paracanthurus. [2] [3] A number of common names are attributed to the species, including regal tang, palette surgeonfish, blue tang (leading to confusion with the Atlantic species Acanthurus coeruleus), royal blue tang, hippo tang, blue hippo tang, flagtail ...
This technique not only is economically beneficial, but serves to promote enhanced water quality through nitrate absorption. The growth of the algae can then be controlled by feeding it to the tang. The growth of the algae can then be controlled by feeding it to the tang.
Marine protists are defined by their habitat as protists that live in marine environments, that is, in the saltwater of seas or oceans or the brackish water of coastal estuaries. Life originated as marine single-celled prokaryotes (bacteria and archaea) and later evolved into more complex eukaryotes. Eukaryotes are the more developed life forms ...
Acanthurinae is the nominate subfamily of the family Acanthuridae which was proposed by the French zoologist Charles Lucien Bonaparte in 1835. [1] The 5th edition of Fishes of the World recognises 3 tribes within the subfamily, the Acanthurini, Prionurini and Zebrasomoni.
Sewage treatment plants mix these organisms as activated sludge or circulate water past organisms living on trickling filters or rotating biological contactors. [5] Aquatic vegetation may provide similar surface habitat for purifying bacteria, protozoa, and rotifers in a pond or marsh setting; although water circulation is often less effective.
Rhodopseudomonas palustris is a rod-shaped, Gram-negative purple nonsulfur bacterium, notable for its ability to switch between four different modes of metabolism. [2]R. palustris is found extensively in nature, and has been isolated from swine waste lagoons, earthworm droppings, marine coastal sediments, and pond water.
Zebrasomini was first proposed as a taxon in 1933 by American ichthyologist Richard Winterbottom, Winterbottom delineated it as consisting of the two genera Zebrasomus and Paracanthurus, alongside the monotypic tribe Prionurini and with the remaining two Acanthurine genera, Acanthurus and Ctenochaetus, being classified in the tribe Acanthurini. [1]
The littoral zone is the uppermost layer and the warmest water found in lakes and ponds, as the sun directly heats is. [7] This zone hosts the most biodiversity in standing water, with a wide variety of organisms found here, vital to the health of the ecosystem and an important aspect of the diet of organisms in the habitat, like algae ...
