The main difference between lobe-finned fish and ray-finned fish lies in their fin structure. Lobe-finned fish have fleshy, lobed fins supported by a bony structure, while ray-finned fish have fins supported by bony rays. Additionally, lobe-finned fish are believed to have given rise to tetrapods, including amphibians, reptiles, birds, and mammals.

Ray-finned fish.
Being ray-finned refers to a characteristic of a large group of fish known as Actinopterygii, which possess fins supported by bony spines or rays. These rays are typically flexible and allow for a wide range of movement, distinguishing ray-finned fish from lobe-finned fish, which have more fleshy, lobed fins. Ray-finned fish include most of the common fish species, such as salmon, trout, and goldfish, and they are characterized by their diverse forms and habitats. This adaptation has allowed them to thrive in various aquatic environments.
The lobe-finned fish and lungfish have jointed appendages, while ray-finned fish have unjointed appendages (pelvic and pectoral fins).
An actinopterygian is a ray-finned fish of the class Actinypterygii.
