Fish anatomy is the study of the form or morphology of fish.It can be contrasted with fish physiology, which is the study of how the component parts of fish function together in the living fish. [1]
Acantopsis is a genus of freshwater fishes, commonly known as horseface loaches or banana-root fishes, in the family Cobitidae. [2] Fishes of the genus Acantopsis inhabit sandy riverbeds throughout Southeast Asia and are most diverse in the Mekong River in Thailand, Laos, and Cambodia wherein five species are known to occur.

At least five extinct genera, known only from fossils, are classified as osteoglossids; these date back at least as far as the Late Cretaceous.Other fossils from as far back as the Late Jurassic or Early Cretaceous are widely considered to belong to the arowana superorder Osteoglossomorpha.
The Asian arowana (Scleropages formosus) comprises several phenotypic varieties of freshwater fish distributed geographically across Southeast Asia. [3] While most consider the different varieties to belong to a single species, [4] [5] [6] [3] [7] work by Pouyaud et al. (2003) [8] differentiates these varieties into multiple species.
The royal angelfish is widely distributed throughout the Indo-Pacific. [4] The species can be found in the Red Sea and Indian Ocean around East Africa and the Maldives, stretching to the Tuamoto Islands, New Caledonia, and Great Barrier Reef. [2]
Structure of a plant cell. Plant cells are the cells present in green plants, photosynthetic eukaryotes of the kingdom Plantae.Their distinctive features include primary cell walls containing cellulose, hemicelluloses and pectin, the presence of plastids with the capability to perform photosynthesis and store starch, a large vacuole that regulates turgor pressure, the absence of flagella or ...
Teleostei (/ ˌ t ɛ l i ˈ ɒ s t i aɪ /; Greek teleios "complete" + osteon "bone"), members of which are known as teleosts (/ ˈ t ɛ l i ɒ s t s, ˈ t iː l i-/), [4] is, by far, the largest group of ray-finned fishes (class Actinopterygii), [a] with 96% of all extant species of fish.
Pterois was described as a genus in 1817 by German naturalist, botanist, biologist, and ornithologist Lorenz Oken.In 1856 the French naturalist Eugène Anselme Sébastien Léon Desmarest designated Scorpaena volitans, which had been named by Bloch in 1787 and which was the same as Linnaeus's 1758 Gasterosteus volitans, as the type species of the genus.
