In biology, an identification key, taxonomic key, or frequently just key, is a printed or computer-aided device that aids in the identification of biological organisms. Historically, the most common type of identification key is the dichotomous key , a type of single-access key which offers a fixed sequence of identification steps, each with ...
The butterflyfish are a group of conspicuous tropical marine fish of the family Chaetodontidae; the bannerfish and coralfish are also included in this group. The approximately 129 species in 12 genera [1] are found mostly on the reefs of the Atlantic, Indian, and Pacific Oceans.
Chaetodon is a tropical fish genus in the family Chaetodontidae. Like their relatives, they are known as "butterflyfish". Like their relatives, they are known as "butterflyfish". This genus is by far the largest among the Chaetodontidae, with about 90 living species included here, [ 1 ] though most might warrant recognition as distinct genera.
The reef butterflyfish lives on rocky and coral reefs [2] to depths of 60 metres (200 ft). [1] Its compressed body means that it can forage by darting in and out of the coral, the small, protractile mouth is a further adaptation to finding food within the coral.
In phylogenetics, a single-access key (also called dichotomous key, sequential key, analytical key, [1] or pathway key) is an identification key where the sequence and structure of identification steps is fixed by the author of the key. At each point in the decision process, multiple alternatives are offered, each leading to a result or a ...
The Hawaiian butterflyfish (Chaetodon tinkeri), also known as Tinker's butterflyfish, is a marine ray-finned fish, a butterflyfish belonging to the family Chaetodontidae of order Perciformes. It is found in the central Pacific Ocean.
The raccoon butterflyfish (Chaetodon lunula), also known as the crescent-masked butterflyfish, lunule butterflyfish, halfmoon butterflyfish, moon butterflyfish, raccoon butterfly, raccoon, raccoon coralfish, and redstriped butterflyfish, is a species of marine ray-finned fish, a butterflyfish belonging to the family Chaetodontidae. It is found ...
These butterfly fish have a viable tolerance to chelated and ionic copper medications, and thus can be kept in quarantine systems that employ these anti-parasitic techniques. These fish, like most butterfly fishes, are territorial and should be kept either singly, or in large systems and added together.
