Butterflyfish
The butterflyfish are a group of conspicuous tropical ocean, marine fish 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 Ocean, Atlantic, Indian Ocean, 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 members of the genus ''Heniochus'' resemble the Moorish idol (''Zanclus cornutus'') of the monotypic Zanclidae. Among the paraphyletic Perciformes, the former are probably not too distantly related to butterflyfish, whereas the Zanclidae seem far less close. Description and ecology Butterflyfish mostly range from in length. The largest species, the lined butterflyfish and the saddle butterflyfish, ''C. ephippium'', grow to . The ...

Chaetodon
''Chaetodon'' is a tropical fish genus in the family (biology), family Chaetodontidae. 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, though most might warrant recognition as distinct genera. Species Extant species There are currently 87 recognized species in this genus: ''Chaetodon sensu stricto'' * ''Chaetodon capistratus'' Linnaeus, 1758 (Foureye butterflyfish) * ''Chaetodon ocellatus'' Marcus Elieser Bloch, Bloch, 1787 (Spotfin butterflyfish) * ''Chaetodon striatus'' Linnaeus, 1758 (Banded butterflyfish) ''C. robustus'' group * ''Chaetodon hoefleri'' Franz Steindachner, Steindachner, 1881 (Four-banded butterflyfish) * ''Chaetodon robustus'' Albert Günther, Günther, 1860 (Three-banded butterflyfish) ''Lepidochaetodon'' group Image:Bep chaetodon punctatofasciatus.jpg, Spotband butterflyfish''Chaetodon (Exornator) punctatofasciatus'' Image:Chaetodon gu ...

Lined Butterflyfish
The lined butterflyfish (''Chaetodon lineolatus'') is a species of marine ray-finned fish. a butterflyfish belonging to the family Chaetodontidae, one of the largest species in the genus ''Chaetodon''. It has a wide range from the Red Sea to South Africa and as far east as southern Japan and Hawaii. Taxonomy It belongs to the large subgenus ''Rabdophorus'' which might warrant recognition as a distinct genus. In this group, it seems to be member of a lineage also containing species such as the spot-naped butterflyfish (''C. oxycephalus''), or the peculiar black-wedged butterflyfish (''C. falcula'') and Pacific double-saddle butterflyfish or "false falcula" (''C. ulietensis''). These four differ wildly in shape, but all have bluish vertical lines on a white body with yellow behind, and black on back and caudal peduncle in addition to the typical eyestripe of ''Chaetodon''. The blue-cheeked butterflyfish (''C. semilarvatus'') seems to be a far more basal lineage of ''Rabdophoru ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Vagabond Butterflyfish
The vagabond butterflyfish (''Chaetodon vagabundus''), also known as the crisscross butterflyfish, is a species of marine ray-finned fish, a butterflyfish belonging to the family Chaetodontidae. It is found in the Indo-Pacific region. Description The vagabond butterflyfish has a whitish body which is marked with two series of thin dark diagonal lines perpendicular to each other, forming a chevron pattern. There is also a wide black vertical band running through the eye and a second band running through the caudal peduncle and a third on the centre of the caudal fin. There are very thin orange horizontal lines over the forehead. The juveniles have a black dot on the soft-rayed part of their dorsal fin, near the posterior end. The dorsal fin contains 13 spines and 23-25 soft rays while the anal fin contains 3 spines and 19-22 soft rays. This species grows to a maximum total length of although a more typical length would be . Distribution The vagabond butterflyfish is found in t ...

Saddle Butterflyfish
The saddle butterflyfish (''Chaetodon ephippium'') is a species of marine ray-finned fish, a butterflyfish belonging to the family Chaetodontidae. It is found in the Indian and Pacific Oceans from Sri Lanka and the Cocos-Keeling Islands to the Hawaiian, Marquesan and Tuamotu islands, north to southern Japan, south to Rowley Shoals and New South Wales in Australia. It is a large butterflyfish, at up to 30 cm (nearly 12 in) long together with the Lined Butterflyfish (''C. lineolatus'') the giant among its genus. In shape it resembles certain angelfishes more than most of its relatives. The overall color is yellowish grey, with a large black spot bordered below by a broad white band on the back and wavy blue lines on the lower sides. The throat and the outline of the hind parts is bright yellow. Adults have a filament extending posteriorly from the upper part of the soft portion of the dorsal fin.

Pacific Double-saddle Butterflyfish
''Chaetodon ulietensis'', the Pacific double-saddle butterflyfish or false falcula butterflyfish, is a species of butterflyfish (family Chaetodontidae). It flourishes in coral-rich environments in the central Indo-Pacific region. Their range extends from the Cocos-Keeling Islands to the Tuamotu Islands, and north to Japan. They are usually found from the surface to 20 m depths, and like shallow channels with high current. Description and systematics These fish can reach a size of . They are white with vertical thin black lines down the body and two dark saddles on the fore and hind back, which softly grade into the background colour caudal gradient. Immediately after the hind quarter saddle, the body and tail is bright yellow swith a black spot on the caudal peduncle. The dorsal fin has a streak of yellow from the crown of the head to the tail.

Eyespot (mimicry)
An eyespot (sometimes ocellus) is an eye-like marking. They are found in butterflies, reptiles, cats, birds and fish. Eyespots could be explained in at least three different ways. They may be a form of mimicry in which a spot on the body of an animal resembles an eye of a different animal, to deceive potential predator or prey species. They may be a form of self-mimicry, to draw a predator's attention away from the prey's most vulnerable body parts. Or they may serve to make the prey appear inedible or dangerous. Eyespot markings may play a role in intraspecies communication or courtship; a well-known example is the eyespots on a peacock's display feathers. The pattern-forming biological process (morphogenesis) of eyespots in a wide variety of animals is controlled by a small number of genes active in embryonic development, including the genes called Engrailed, Distal-less, Hedgehog, Antennapedia, and the Notch signaling pathway. Artificial eyespots have been shown to reduce ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Pomacanthidae
Marine angelfish are perciform fish of the family Pomacanthidae. They are found on shallow reefs in the tropical Atlantic, Indian, and mostly western Pacific Oceans. The family contains seven genera and about 86 species. They should not be confused with the freshwater angelfish, tropical cichlids of the Amazon Basin. Description With their bright colours and deep, laterally compressed bodies, marine angelfishes are some of the more conspicuous residents of the reef. They most closely resemble the butterflyfishes, a related family of similarly showy reef fish. Marine angelfish are distinguished from butterflyfish by the presence of strong preopercle spines (part of the gill covers) in the former. This feature also explains the family name Pomacanthidae; from the Greek πομα, ''poma'' meaning "cover" and ακάνθα, ''akantha'' meaning "thorn". Many species of marine angelfishes have streamer-like extensions of the soft dorsal and anal fins. The fish have small mouths ...

Heniochus
''Heniochus'' is a genus of marine ray-finned fish, butterflyfishes from the family Chaetodontidae. They are native to the Indo-Pacific. Though very similar in appearance to the Moorish idol ''( Zanclus cornutus)'', the members of this genus are not closely related to it. Characteristics ''Heniochus'' species are distinguished within the Chaetodontidae by having the fourth spine in the dorsal fin elongated, or even forming a filament. The supraorbital crests in adults have spines or horn-like protuberances. They normally have a hump, or at least a robust bony growth on the nape. Etymology ''Heniochus'' is Greek for a “carriage driver” or “coachman” and is a reference to the long, filamentous 4th dorsal spine of these fish, resembling the whip of a coachman. Species There are currently eight recognized species in this genus: * '' Heniochus acuminatus'' (Linnaeus, 1758) (Pennant coralfish) * '' Heniochus chrysostomus'' G. Cuvier, 1831 (Threeband pennantfish) * '' Heni ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Schooling Bannerfish
The schooling bannerfish (''Heniochus diphreutes''), also known as the false moorish idol, is a marine ray-finned fish, a butterflyfish from the family Chaetodontidae. It is native to the Indo-Pacific area.

Moorish Idol
The Moorish idol (''Zanclus cornutus'') is a species of marine ray-finned fish belonging to the family Zanclidae. It is the only member of the monospecific genus ''Zanclus'' and the only extant species within the Zanclidae. This species is found on reefs in the Indo-Pacific region. Taxonomy The Moorish idol was first formally described as ''Chaetodon cornutus'' in 1758 by Carl Linnaeus in the 10th edition of the ''Systema Naturae'' with "Indian Seas" given as its type locality. In 1831 Georges Cuvier classified it in the new monospecific genus ''Zanclus''. In 1876 Pieter Bleeker proposed the monotypic family Zanclidae. The Zanclidae is classified within the suborder Acanthuroidei of the order Acanthuriformes. Some authors classify the Moorish idols in the surgeonfish family Acanthuridae but the absence of spines on the caudal peduncle is a clear difference between this species and the surgeonfishes. The Moorish idol is the only extant member of its family, the Zanclidae, maki ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
