Ray finned fish have webs of skin supported by bony or horny spines. These spines are called rays. Goldfish have these types of fins.
Yes because it is a vertebrate There are five types of vertebrates, and goldfish belongs to 'fish'. As it is a vertebrate, it has a backbone.
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.
The three classes of bony fish are Actinopterygii (ray-finned fish), Sarcopterygii (lobe-finned fish), and Dipnoi (lungfish). Ray-finned fish have fins supported by bony rays, lobe-finned fish have fleshy lobed fins, and lungfish are known for their ability to breathe air.
The three vertebrate classes of fish are: Agnatha (jawless fish without scales, e.g. lampreys and hagfish)Chondrichthyes (sharks and rays, which have skeletons of cartilage rather than bone)Osteichthyes (all the bony fish e.g. tuna, trout, whiting, etc.)
The most diverse group of fish is the ray-finned fishes (Actinopterygii). This group includes over 30,000 species and accounts for nearly half of all vertebrate species. Ray-finned fishes have a wide range of body shapes, sizes, habitats, and lifestyles.
