Sharks have two sets of paired fins on the sides of their body, in the same general position as the main wings and horizontal tail wings of a plane. The shark can position these fins at different angles, changing the path of the water moving around them.
When it comes to the shark having the ability to propel itself through the water, they utilize what is called the caudal fin. This fin, also known as the tail fin, has an upper and lower lobe that, depending on the type of shark, can vary in shape and size.
