Yes, shark dorsal fins are triangular and straight while dolphin dorsal fins are very curved and streamlined.
A Google Image Search will clarify this even better.
A dolphin's fin is rounded at the top, but a shark's fin is straight
Dried shark fins are exactly that: they are the fins, especially the dorsal fin, of a live shark that have been dried.
dorsal, in anatomy at least, means towards the back side of the body. the reason why fish have a dorsal fin is because its on their back, like a shark fin.
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 dog is kind of like a dolphin with four arms and barks it is very valuable
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.

No, sharks need their dorsal fins to keep them upright and traveling straight.
a dolphin can only swim up and down because its muscle structure and it spine are designed that way, if a dolphin were to swim side to side the muscle near its tail would swell damaging the spine if a shark or fish were to swim like a dolphin the same thing would happen eventually resulting in death.
Shark is to fish dolphin is to mammal.
The fins on a dolphin, whale, shark, basically all marine life, have evolved in such a way as to exemplify their strengths. A dolphins strength is to be fast and agile. Their fins help them to navigate the waters in the most energy efficient maner. Their flukes (tails) are incredibly strong and help to propel them through the ocean/lakes/and rivers. Also the dolphins fluke moves up and down, not side to side like a shark.
