Can you eat payara fish?

What makes a fish a teleost?

Teleosts are distinguished primarily by the presence of a homocercal tail, a tail in which the upper and lower halves are about equal. The teleosts comprise some 30,000 species (about equal to all other vertebrate groups combined), with new species being discovered each year.

Why are teleost fish so diverse?

It was thought that the genome duplication might accelerate the rate at which the group could modify existing traits and evolve new features, giving them access to new environments or lifestyles. In other words, there was something inherently special about teleosts that gave them remarkable abilities to diversify.

Can we physically differentiate between a teleost and a non teleost fish?

The difference between teleosts and other bony fish lies mainly in their jaw bones; teleosts have a movable premaxilla and corresponding modifications in the jaw musculature which make it possible for them to protrude their jaws outwards from the mouth.

Which fish are finned fish?

Ray-finned fishes make up about half of all known vertebrate species. This group of fish is very diverse, so species come in a wide variety of shapes, sizes, and colors. The ray-finned fishes include some of the most well-known fish, including tuna, cod, lionfish, and even seahorses.

Why are teleost fish so successful?

Numerous ideas have been put forward to explain teleost success, including the flexible structure of their jaws, a diversity of reproductive strategies and the symmetry of their tail fins.
