Sharks have five different types of fins located on their bodies. All sharks have pectoral fins on either side of their bodies. They also have one or two dorsal fins and anal fins, while others only some possess pelvic fins near their tails. The caudal fin is most popular for its other term, the shark’s tail.
The 5 Types of Shark Fins
This fish has three different types of median fins (anal, dorsal, and caudal) as well as two pairs of smaller paired fins (pectoral and pelvic).
Though not all shark species have anal fins, those that do have them on the bottom of their body between the pelvic and tail fins. Furthermore, they maintain stability and assist in the shark’s movements.
The number of dorsal fins varies by species, but there are usually one or two. The most visible dorsal fin is often the first one located on the shark’s head, as it is often visible above water. The dorsal fins of a shark play an important role in its swimming; they help the animal stay balanced and swim smoothly.
Shark tails are more commonly known as their caudal fins. In order to move through the water, sharks glide these fins from side to side. Sharks cannot move backward because their fins are designed in a way that prevents it. Consequently, if a shark wants to escape something, it must either glide away from the object or turn around and swim forward.
Each side of a shark’s body has a pectoral fin located behind its head. These appendages are often lengthy and help to stop the shark from dropping down to the ocean’s depths, as well as forcing it to swim in a particular direction.
The pelvic fins are a set of two fins located near the tail. These fins are located on the shark’s bottom side and help to keep it level so that it does not drift too far in one direction. The main function of a shark’s pelvic fin is steering while swimming and providing lift.
Can Sharks Survive When A Fin Is Torn Off?
Shark-finning is a cruel and inhumane practice in which sharks are caught, their fins are mercilessly cut off, and then the bodies of the defenseless animals are unceremoniously discarded. They’re returned to the ocean, where they then bleed out or are eaten alive defenselessly by other marine creatures.
Sharks have five different fins on their bodies, each of which plays an important role in helping the animal swim and maneuver. Each type of fin has a specific purpose and shape, so it is essential that these appendages stay intact for the shark to survive. We hope that understanding the fins of a shark helps to emphasize how important they are and why shark finning must be stopped.
