Fish which have become recently extinct are not usually referred to as prehistoric fish. Lists of various prehistoric fishes include: List of prehistoric jawless fish; List of ...
Coelacanth eggs are large, with only a thin layer of membrane to protect them. Embryos hatch within the female and eventually are born alive, which is a rarity in fish.

[70] [71] Controversy still exists since Tiktaalik, a vertebrate often considered the missing link between fishes and land-living animals ...
Arandaspis prionotolepis. This list of prehistoric jawless fish is an attempt to create a comprehensive listing of all genera from the fossil record that have ever been considered to be jawless fish, excluding purely vernacular terms.

As a species, sturgeon are one of the oldest still swimming. Having first emerged over 120 million years ago , they lived alongside dinosaurs and survived the catastrophic hurdles and curveballs ...

The bony fish evolved into two separate groups: the Actinopterygii (or ray-finned fish) and Sarcopterygii (which includes the lobe-finned fish).
