Os teleósteos (Teleostei) son unha infraclase da clase Actinopterixios (Actinopterygii) e comprenden a inmensa maioría dos peixes óseos actuais.

Características

[editar | editar a fonte]

Son peixes de esqueleto óseo, cola homocerca, escamas cicloides o ctenoideas, vexiga natatoria habitualmente presente e sen espiráculos.

Presentan placas dentarias basibranquiais [3] e premaxilares móbiles.

Clasificación

[editar | editar a fonte]

Clasificáronse como unha superorde dos Actinopterixios porque o grao de osificación do seu esqueleto era superior ó dos Condrósteos e Holósteos, pero hoxe considéranse unha infraclase.

Os Teleósteos comprenden 12 superordes coas seguintes ordes:

Muxo
Zamborca
Carpa
Troita
