These are [[acanthomorph]] [[teleost]]s which diverged at the end of the [[Cretaceous]] or in the succeeding [[Paleocene]] period, 60-70 million years ago. Their sister order is the [[Myctophiformes]]. Lampriforms have a highly variable body form, but they are usually deep-bodied or elongate. The [[premaxilla]] completely excludes the [[maxilla]] from the gape. However, the [[jaw]]s are highly protrusible, with a unique type of protrusible upper jaw. The maxilla, instead of being ligamentously attached to the [[ethmoid]] and [[Palatine bone|palatine]], slides in and out with the highly protractile premaxilla. The lampridiforms have 84-96 total [[vertebra]]e, but lack fin spines. The [[pelvic fin]]s have 0-17 rays and are placed rather far toward the front of the animal. The [[dorsal fin]]s are long, and tend to run most of the length of the body. They lack scales. The fishes are normally found at depth 100-1000 m but are [[pelagic zone|pelagic]], not bottom feeders. == References == *{{FishBase_order|order=Lampriformes|year=2005|month=February}} {{Actinopterygii}} [[Category:Lampriformes| ]] [[da:Lampridiformes]] [[de:Glanzfischartige]] [[es:Lampridiformes]] [[fr:Lampridiformes]] [[it:Lampridiformes]] [[lt:Vėduokliažuvės]] [[hu:Tündöklőhal-alakúak]] [[nl:Koningsvissen]] [[ja:アカマンボウ目]] [[no:Båndfisker]] [[oc:Lampridiformes]] [[pl:Strojnikokształtne]] [[zh:月魚目]]
