Sharks, skates, and rays form a group of fishes also known as the elasmobranchs. There are about 800 species of this group, over half of which are skates and rays. The remainder of the group are sharks.
Sharks, when compared to skates and rays, are designed more for speed and power. Many species rely on agility to capture prey. Their bodies are torpedo-like in shape, streamlined for quick movement through the water. The thickest part of their body is about one third of the way back from the head, and it tapers off from there in a form that reduces drag when swimming. Sharks propel themselves through the water by moving their tail fins laterally back and forth.
The bodies of skates and rays, in contrast to sharks, are flattened into disc or diamond shapes. They have reduced tail fins and swim by undulating their fins on each side of the body up and down in a wave-like manner. Many species of rays and skates are either bottom feeders or filter feeders.
