The freshwater butterflyfish is a specialized surface hunter. Its eyes are constantly trained to the surface and its upturned mouth is specifically adapted to capture small prey along the water's surface. If enough speed is built up in the water, a butterflyfish can jump and glide a small distance above the surface to avoid predation. It also ...
Butterflyfish mostly range from 12 to 22 cm (4.7 to 8.7 in) in length. The largest species, the lined butterflyfish and the saddle butterflyfish , C. ephippium , grow to 30 cm (12 in). The common name references the brightly coloured and strikingly patterned bodies of many species, bearing shades of black, white, blue, red, orange, and yellow.
An oscar, Astronotus ocellatus, surveys its environment. Vision is an important sensory system for most species of fish.Fish eyes are similar to the eyes of terrestrial vertebrates like birds and mammals, but have a more spherical lens.
Chaetodon is a tropical fish genus in the 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, [1] though most might warrant recognition as distinct genera.
The Cretaceous marine pantodontids are among the earliest known marine osteoglossomorph genera. [1] They physically differ greatly from Pantodon, to the extent that some of them were previously considered either ancestral codlets or crestfish, [2] but they all share specific cranial elements with the extant Pantodon, supporting their relationship to it.
The scrawled butterflyfish is found at depths between 2 and 25 metres (6.6 and 82.0 ft) where it inhabits area rich in coral in clear lagoons and seaward reefs. The juveniles are normally solitary and live among branching corals while the adults typically live as pairs and have a home range. They are oviparous and breed in pairs. [2]
The bluecheek butterflyfish is one of the few fish species to have long-term mates. [4] In the wild, the fish eats hard corals as well as benthic invertebrates. [5] This is a common species which is found in areas with rich coral growth.
