A great white dorsal fin does always stay upright in the water. The fin is what helps the shark swim.

Why does an orcas fins fold over?
They dont just fold over its because they were caught in a net and the fins bends It is theorized that when the orcas experience their growth spurt as juveniles they require both swimming and the force of the water to support the weight of the fin. The dorsal fin can weigh up to 200 pounds, thus, the water is required as a force against the weight to keep it upright. The fin is largely cartlidge. Additionally, orcas swim in the wild about 75 to 100 miles a day so it is believed that swimming strengthens the fin to stand upright. At least this is what I have read; I have to assume that all of the capitve orcas with collapsed fins either were born in captivity or were captured when juveniles.
Why do they need a soft dorsal fin?
dolphins need a soft dorsal fin because of their way of swimming. If they were to have a hard, sharp, stiff or even ruff fin it would put weight on them and e tilt them to the side which then would interfere with their other fins.

Why does the orca dorsal fin fall in captivity?
Most male captive Orcas, and some females, have collapsed (droopy) dorsal fins. Several theories exist as to why this happens. A dorsal fin is held erect by collagen, or compressed lipid cells. The collagen normally hardens in late adolescence. One theory is that in deep ocean waters, the pressure the water exerts on the fin allows it to remain supported while the collagen hardens. In captivity, however, shallow tanks lack sufficient water pressure to produce this effect, and the fin collapses before the collagen solidifies. According to another theory, the Orca is almost always in a state of turning in a tank, since it is not large enough to allow swimming in one direction for any normal duration. The constant turning exerts pressure on the dorsal fin, which in turn causes it to collapse.Other possible explanations include alterations in water balance caused by the stresses of captivity or dietary changes, lowered blood pressure due to reduced activity patterns, or overheating of the collagen brought on by greater exposure of the fin to the ambient air.In the wild, dorsal fin collapse is rare, and the deformity is believed to have a different set of causes than in captivity. In wild Orcas, it usually results from a serious injury to the fin. After the 1989 Exxon Valdez oil spill, the dorsal fins of two male resident Orcas who had been exposed to the oil collapsed, and the animals subsequently died. In 2002, the dorsal fin of a stranded Orca showed signs of collapse after three days, but regained its natural upright appearance as soon as the whale resumed strong normal swimming upon release.
Does the beluga whale have a dorsal fin?
The dorsal fin is the fin on the back of a swimming animal's body. It helps the creature steer through the water like a rudder. A orca, or killer whale, has a very tall dorsal fin. The dorsal fin of the male is taller than the dorsal fin of the female. The male's dorsal fin can reach a height of seven feet, while the female's fin can be 5 feet tall. Killer whales in the wild have dorsal fins that stick straight up in the air. Almost all killer whales in capitivity have dorsal fins that droop over like a floppy dog's ear.
