Fish
Fish are aquatic, craniate, gill-bearing animals that lack limbs with digits. Included in this definition are the living hagfish, lampreys, and cartilaginous and bony fish as well as various extinct related groups. Approximately 95% of living fish species are ray-finned fish, belonging to the class Actinopterygii, with around 99% of those being teleosts. The earliest organisms that can be classified as fish were soft-bodied chordates that first appeared during the Cambrian period. Although they lacked a true spine, they possessed notochords which allowed them to be more agile than their invertebrate counterparts. Fish would continue to evolve through the Paleozoic era, diversifying into a wide variety of forms. Many fish of the Paleozoic developed external armor that protected them from predators. The first fish with jaws appeared in the Silurian period, after which many (such as sharks) became formidable marine predators rather than just the prey of arthrop ...

Bigeye Searsid
The Priacanthidae, the bigeyes, are a family of 18 species of marine ray-finned fishes. " Catalufa" is an alternate common name for some members of the Priacanthidae. The etymology of the scientific name (, to bite + , thorn) refers to the family's very rough, spined scales. The common name of "bigeye" refers to the member species' unusually large eyes, suited to their carnivorous and nocturnal lifestyles. Priacanthidae are typically colored bright red, but some have patterns in silver, dusky brown, or black. Most species reach a maximum total length of about , although in a few species lengths of over are known. Most members of this family are native to tropical and subtropical parts of the Indian and Pacific Oceans, but four species ('' Cookeolus japonicus'', ''Heteropriacanthus cruentatus'', '' Priacanthus arenatus'', and ''Pristigenys alta'') are found in the Atlantic. They tend to live near rock outcroppings or reefs, although a few are known to inhabit open waters. Ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
