List four characteristics of teleosts that contributed to their incredible diversity and success.

Four characteristics are that they have several morphological trends in the teleost lineage that allowed them to diversify into the incredible variety of habitats and forms. They also have a heavy dermal anchor of primitive ray-finned fishes. Some lack scales and this helps to increase mobility and speed that resulted from heavy armor improved predator avoidance and feeding efficiency. Another characteristic that contributed to their success was te symmetrical shaped homocercal tail that resulted in greater speed.


teleosts are the major lineage of neopterygians, the modern bony fishes. They are very diverse; 23,600 described species, representing about 96% of all living fishes or half of all vertebrates. ds
