Fish are categorized into three key varieties primarily based on their own skeletal construction and respiratory systems:

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

Cartilaginous Fish (Chondrichthyes): Fish like sharks, rays, and skates drop into this team, characterised by skeletons made from cartilage. They ordinarily have several gill slits without handles.

Jawless Fish (Agnatha): Primitive fish like lampreys and hagfish belong to this category. Contrary to other fish, they lack jaws and rely upon suction or other special feeding methods.
