Acipenseriforms are a group of fish that fall into condrosteos and holosteos.

Condrostes or sturgeon

Are fish found in temperate regions of the Northern Hemisphere.

The skin lacks scales and has only five longitudinal rows of plates rhomboids and pointed.

The head has wider plates.
The skeleton is not fully ossified.
The tail is heterocerca (two unequal sides).

Typical representatives are the sturgeons and paddlefish.

The sturgeon roe are the basis of the famous caviar.

Sturgeons are very primitive fish preserved ancient characters, such as shields or plates.

The mouth without teeth, located in the ventral part, is sucking small animals, such as worms, snails, etc.., Detected by four appendices or chins that are sweeping the background.

Holosteos

They are very primitive fish, of which there are only lepisosteos and amia.

Plates are coated, ganoid calls, which are coupled side by side in the form of plates.
The lepisosteos are very large and voracious, with many teeth.
One grows to 4 meters and is called freshwater shark, and living only in North American rivers.
The paddlefish are relatives of sturgeons, and only found in the Mississippi River and the Yangtze River in China.
The bowfin is a curious holósteo fish inhabiting large lakes and rivers of North America.
