The oldest known fossils of bony fish are about 425 million years old from the late Silurian, [1] which are also transitional fossils showing a tooth pattern that is in between the tooth rows of sharks and true bony fishes. [4] Despite the name, these early basal bony fish had not yet evolved ossification and their skeletons were still mostly ...
The bony-eared assfish (Acanthonus armatus) is a bathypelagic species of cusk-eel found in tropical and sub-tropical oceans at depths of from 1,171 to 4,415 metres (3,842 to 14,485 ft). It has been found as far north as Queen Charlotte Sound off British Columbia 's coast. [ 7 ]
Actinopterygii (/ ˌ æ k t ɪ n ɒ p t ə ˈ r ɪ dʒ i aɪ /; from Ancient Greek ἀκτίς (aktis) 'having rays' and πτέρυξ (ptérux) 'wing, fins'), members of which are known as ray-finned fish or actinopterygians, is a class of bony fish [2] that comprise over 50% of living vertebrate species. [3]
The ocean sunfish (Mola mola), also known as the common mola, is one of the largest bony fish in the world. It is the type species of the genus Mola, and one of five extant species in the family Molidae. [6] [7] It was once misidentified as the heaviest bony fish, which was actually a different and closely related species of sunfish, Mola ...
By the start of the Early Devonian, 419 million years ago, jawed fishes had divided into three distinct groups: the now extinct placoderms (a paraphyletic assemblage of ancient armoured fishes), the bony fishes, and the clade that includes spiny sharks and early cartilaginous fish. The modern bony fishes, class Osteichthyes, appeared in the ...
Coelacanths are a part of the clade Sarcopterygii, or the lobe-finned fishes. They share membership in this clade with lungfish and tetrapods. Externally, several characteristics distinguish coelacanths from other lobe-finned fish. They possess a three-lobed caudal fin, also called a trilobate fin or a diphycercal tail. A secondary tail ...
Leedsichthys, a giant Jurassic pachycormid. This list of prehistoric bony fish is an attempt to create a comprehensive listing of all genera from the fossil record that have ever been considered to be bony fish (class Osteichthyes), excluding purely vernacular terms.
Arowanas are freshwater bony fish of the subfamily Osteoglossinae, also known as bony tongues [1] (the latter name is now often reserved for Arapaiminae). [2] In this family of fish, the head is bony and the elongated body is covered by large, heavy scales, with a mosaic pattern of canals.
