Catfish connection to Ray-Finned fish: Knowledge Snip

Catfish are a diverse group of fish that are classified within the order Siluriformes. They are closely related to ray-finned fish, which are a diverse group of fish that are classified within the class Actinopterygii. Both catfish and ray-finned fish are members of the superclass Osteichthyes, which includes all bony fish.

One of the key characteristics that distinguishes catfish from other types of fish is the presence of barbels, or whiskers, around their mouth and head. These barbels are used to locate food in the water and are an important adaptation for catfish, who often live in environments with poor visibility.

Despite their close relationship, catfish and ray-finned fish have some notable differences. Catfish are generally more adapted to life in freshwater environments, while ray-finned fish are found in both freshwater and marine environments. Ray-finned fish also have a more streamlined body shape, which allows them to swim more efficiently, while catfish tend to have a more flattened and elongated body shape.

Overall, catfish and ray-finned fish are both important groups of fish that are known for their diverse and interesting characteristics. They have a close evolutionary relationship and share many common features, but also have some notable differences that set them apart.
