What Are the key Kinds ofFish?
Fish are classified into 3 primary styles based mostly on their skeletal composition and respiratory techniques:

Bony Fish (Osteichthyes): This category incorporates species like salmon, trout, and cod, accounting for around ninety six% of all fish species. Their skeletons are made of bones, and they have operculum (gill addresses) for breathing.

Cartilaginous Fish (Chondrichthyes): Fish like sharks, rays, and skates slide into this group, characterised by skeletons manufactured from cartilage. They typically have many gill slits without having handles.

Jawless Fish (Agnatha): Primitive fish like lampreys and hagfish belong to this class. Unlike other fish, they absence jaws and rely on suction or other exceptional feeding techniques.
