Because they need to be shaped aerodynamically to easily swim through the water.
Golgi bodies
Skates look similar to sting rays. They are flattened cartilagenous fish, and have tails. Their bodies look like a flattened disk or plate. Generally skates have a pointed front/nose where rays have a rounded front. They are closely related to rays.

Bilateral flattening is characteristic of many fish species, but one notable example is the flounder. These fish have evolved to have a flattened body shape, allowing them to lie flat on the ocean floor. This adaptation helps them blend in with their surroundings, providing camouflage from predators. Other examples of bilaterally flattened fish include sole and halibut.
The flat fish you are referring to is called a "ray." This term is often associated with several species of flat fish, including skates and rays within the order Rajiformes. These fish are characterized by their flattened bodies and wing-like pectoral fins, allowing them to glide along the ocean floor.
Yes, stingrays are carnivores. They mainly feed on small fish, crustaceans, and mollusks that live on the ocean floor. They use their flattened bodies to efficiently glide through the water in search of prey.
