1. Superorder Acanthopterygii

2. General information
Acanthopterygii is a superorder within the class teleostei.
This superorder contains a remarkably diversity of the higher spiny- rayed fishes with 14,800 species in 267 families.

3. The Acanthoperygii are being distinguished by:
A maximal upper jaw mobility and protrusibility;
The high developed level of pharyngeal dentition and action.

4. Other features Acanthopterygians typically charactarize:
Ctenoid scales;
A physoclistous gas bladder;
Two distinct dorsal fins, which of one is spiny and the other is soft- rayed;
Pelvic and anal fins with spines;
And a number of trends in feeding, locomotion, and predator protection.

5. Acanthopterygian species
Lionfish (Scorpaeniformes)
Tuna (Scombridae)
Anglerfish (Lophiiformes)

Collette B and 8 others (2011). "Thunnus maccoyii". IUCN Red List of Threatened Species. Version International Union for Conservation of Nature. Retrieved 9 January "This species has been intensively fished since the early 1950s. Its generation length is conservatively estimated to be 12 years. Estimated spawning stock biomass has declined approximately 85% over the past 36 years (1973–2009) and there is no sign that the spawning stock is rebuilding. It is therefore listed as Critically Endangered. Implementation of effective conservation and management measures are urgently needed.“
