Chondrichthyes is a class of cartilaginous fish that includes sharks, rays, and skates. Sharks, such as the great white shark, are known for their streamlined bodies and powerful jaws. Rays, like the manta ray, have flattened bodies and are often found gliding through the ocean. Skates are similar to rays but typically have a more rounded body shape and are often found on the sea floor.

What are the three vertebrate classes of fish?

What are the classifications of fish?
Fish are classified into three main groups: Agnatha (jawless fish such as lampreys), Chondrichthyes (cartilaginous fish such as sharks and rays), and Osteichthyes (bony fish such as salmon and tuna). Osteichthyes are further divided into two subclasses: Actinopterygii (ray-finned fish) and Sarcopterygii (lobe-finned fish).
How do chondrichthyes move in the water?
Chondrichthyes, or cartilaginous fish like sharks and rays, move in the water by using their powerful tail muscles to create thrust and propel themselves forward. They also have streamlined bodies and pectoral fins that help them maneuver and control their direction as they swim. Additionally, some species of chondrichthyes can adjust the position of their pectoral fins to generate lift and maintain buoyancy.
