ButterflyfishThe butterflyfish are a group of conspicuous tropicalmarinefish of the family Chaetodontidae; the bannerfish and coralfish are also included in this group. The approximately 129 species in 12 genera are found mostly on the reefs of the Atlantic, Indian, and Pacific Oceans. A number of species pairs occur in the Indian and Pacific Oceans, members of the huge genus Chaetodon. Butterflyfish look like smaller versions of angelfish (Pomacanthidae), but unlike these, lack preopercle spines at the gill covers. Some mem...
ActinopterygiiActinopterygii (; from Ancient Greekἀκτίς (aktís)'ray, beam' and πτέρυξ (ptérux)'wing, fins'), members of which are known as ray-finned fish or actinopterygians, is a class of bony fish that constitutes nearly 99% of the over 30,000 living species of fish. The vast majority of extant actinopterygian species are teleosts, and by species count they dominate the subphylumVertebrata, comprising over 50% of all living vertebrates. They are the most abundant nektonicaquatic animals and are ubiquitous thr...
AnimalAnimals are multicellular, eukaryoticorganisms belonging to the biologicalkingdomAnimalia (). Animals consume organic material, breathe oxygen, have myocytes, can reproduce sexually, and grow from a hollow sphere of cells, the blastula, during embryonic development. With few exceptions, animals are able to move. Animals form a clade, meaning that they arose from a single common ancestor. Over 1.5 million living animal species have been described, of which around 1.05 million are insects, over 85,000 are molluscs...
AcanthuriformesAcanthuriformes is a large, diverse order of mostly marine ray-finned fishes, part of the Percomorphaclade. In the past, members of this clade were placed in the suborders Acanthuroidea and Percoidea of the order Perciformes, but this treatment is now considered paraphyletic. This order contains many of the iconic tropical reef fish groups, such as surgeonfish, marine angelfish, butterflyfish, rabbitfish, grunts, and snappers. It also contains widespread, economically important food and sport fishes, such as dru...*As an Amazon Associate I earn from qualifying purchases.
