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.
The anal fin is located between the pelvic and caudal fins on the bottom, or ventral, part of the shark. Caudal Fins 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. The upper lobe of the caudal fin produces the majority of the sharkâs thrusting abilities. The tail fin is one of the most important parts of the entire shark anatomy. Types Of Shark Tail Fins Because of all of these different types of fins, sharks are able to maneuver swiftly through the water while also remaining stabilized.
