Lamprimorpha
Lamprimorpha is a superorder of marine ray-finned fishes, representing a basal group of the highly diverse clade Acanthomorpha. Represented today only by the order Lampriformes (containing oarfish, crestfish, and opahs, among others), recent studies have recovered other basal fossil species of the group (most of which were previously classified in other clades) dating as far back as the Cenomanian stage of the Late Cretaceous. Some of these fossil taxa, such as the paraphyletic genus '' Aipichthys'', are among the oldest known fossil acanthomorphs, and overall they appear to have been a major component of the marine fish fauna at that time. Lamprimorpha is thought to be the sister group to the superorder Paracanthopterygii, which contains cod, dories, and trout-perches; however, Lamprimorpha may instead be sister to Acanthopterygii. It was initially described as Lampridomorpha, although this is considered a misspelling by ''Fishes of the World'', which refers to it as Lampri ...

Bathysomi
Lampriformes is an order (biology), order of Actinopterygii, ray-finned fish. Members are collectively called lamprids (which is more properly used for the Opah, Lampridae) or lampriforms, and unite such open-ocean and partially Deep sea, deep-sea Teleostei as the crestfishes, oarfish, opahs, and ribbonfishes. A synonym (biology), synonym for this order is Allotriognathi, while an often-seen, but apparently incorrect, spelling variant is Lampridiformes. They contain seven extant family (biology), families which are generally small but highly distinct, and a mere 12 lampriform genera with some 20 species altogether are recognized. They are the only extant members of the superorder Lamprimorpha, which was formerly diverse throughout much of the Late Cretaceous. The Binomial nomenclature, scientific name literally means "shaped (like the) bright (one)", as "lampr-", meaning bright, comes from ''lampris'', the generic name for the opah. In contrast, most other living lampriforms are ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
