Exactly what are the primary Types ofFish?
Fish are classified into 3 main styles dependent on their skeletal composition and respiratory programs:
Bony Fish (Osteichthyes): This category features species like salmon, trout, and cod, accounting for around 96% of all fish species. Their skeletons are created of bones, and they've got operculum (gill covers) for respiration.
Cartilaginous Fish (Chondrichthyes): Fish like sharks, rays, and skates drop into this team, characterized by skeletons made of cartilage. They commonly have numerous gill slits without the need of addresses.
Jawless Fish (Agnatha): Primitive fish like lampreys and hagfish belong to this category. Contrary to other fish, they lack jaws and trust in suction or other special feeding methods.
