Knowra Teleost Teleost A teleost is a ray-finned fish belonging to Teleostei, an infraclass that includes most living fish species. Teleosts are distinguished by a largely ossified skeleton and a mobile upper jaw.
Teleostei : Teleostei is an infraclass of ray-finned fishes containing the great majority of living fish species. The taxonomic group to which every teleost belongs.
Teleost jaw protrusion : Teleost jaw protrusion is the forward extension of the jaws during feeding, often created by linked skull movements. It lets many teleosts seize prey rapidly, sometimes from a distance.
Aquaculture : Aquaculture is the farming of aquatic organisms, including fish, shellfish, and aquatic plants. Many farmed fish, including salmon and tilapia, are teleosts.
Chondrichthyes : Chondrichthyes is the class of cartilaginous fishes, including sharks, rays, and chimaeras. Unlike teleosts, chondrichthyans have skeletons made primarily of cartilage.
Teleost genome duplication : Teleost genome duplication was an ancient whole-genome duplication in the ancestry of teleost fishes. The duplication supplied genetic material later diversified across teleost lineages.
Actinopterygii : Actinopterygii is the class of fishes whose fins are supported by bony rays. Teleosts are one major lineage within this broader ray-finned fish group.
Weberian apparatus : The Weberian apparatus is a chain of small bones connecting the swim bladder to the inner ear in otophysan fishes. This teleost specialization improves hearing by transmitting vibrations from the swim bladder.
Fisheries science : Fisheries science studies fish populations and their management, harvest, and conservation. Most commercial finfish fisheries target teleost species.
Holostei : Holostei is a lineage of ray-finned fishes that includes gars and bowfin, outside Teleostei. These living non-teleost ray-finned fishes provide a nearby evolutionary comparison.
Teleost radiation : The teleost radiation is the evolutionary diversification that produced the group’s exceptional species richness. It accounts for the breadth of forms and habitats represented by living teleosts.
