No.
Elasmobranchs such as rays and sharks lack nociceptors, the nerves that translate noxious stimuli into neural signals.
Nociceptors appear in bony fish and basically all later vertebrates, as well as some invertebrates, but are absent in cartilaginous fish such as sharks.
The dorsal fin is the fin on the back of a fish, for example the typical triangular fin on the back of a shark is its dorsal fin.

An orcas dorsal fin (the fin on the back of a aquatic mammal, so times on a shark) can get to be 6 feet tall.
A shark with a long dorsal fin can be distinguished from other shark species by its distinctive feature of having a dorsal fin that is longer than usual. This unique characteristic sets it apart from other sharks and helps in identifying the specific species.
To accurately identify a shark based on its dorsal fin characteristics, look at the shape, size, and color of the fin. Each shark species has a unique dorsal fin shape and pattern, which can help in identification. Additionally, pay attention to any distinctive markings or scars on the fin that may be specific to certain species.

A great white dorsal fin does always stay upright in the water. The fin is what helps the shark swim.
The dorsal fin of a dolphin is usefu,l because it can control the balance when a dolphin is swimming.It can also be useful for signs of dolphins and not sharks because the dorsal fin of a dolphin and a shark is slightly different.
They allow the shark to swim. A shark with no fins would be unable to swim. Any individual fin provides steering and propulsion depending on exactly which fin you're talking about. The dorsal fin (the one on top of the shark that sticks up above the water in any cartoon about a shark) is mainly for steering.
A shark with two dorsal fins is distinguished from other shark species by its double dorsal fin arrangement, which is not commonly seen in most shark species.
