Why do orca dorsal fins flop over?

What does SeaWorld say about collapsed dorsal fins?
SeaWorld announced in 2016 that it would stop breeding whales in captivity immediately and phase out killer whale shows at all its parks by 2019. (In San Diego, the shows ended in 2017.) The company has said, however, that the shape of a killer whale’s dorsal fin is not an indicator of its health.
Are killer whales fins supposed to be bent?
Contrary to popular belief, it’s not just in captive whales. The phenomenon is more common in captivity, but people have also seen wild orcas with curved fins. In captivity, whales breach the surface more often, exposing their fins to the warmer air. It doesn’t take long for this process to happen.
What is the relationship between marine mammals and orcas?

Do orcas and dolphins get along?
Barrett-Lennard said while it might be unexpected to see dolphins hanging out with orcas, it’s not at all unusual to see dolphins hanging out with other dolphin and whale species. “They’re not xenophobic … they’re attracted to other species in general, and this is an extreme case of that.”
Why are orcas considered dolphins?
While orcas are members of the marine dolphin family Delphinidae, their overall size is what sets them apart from others in their suborder. Today, if a dolphin reaches a size of more than 30 feet long, it may be referred to by some as a whale, but the rules of taxonomy still classify the orca as a dolphin.

Do orcas in captivity have collapsed dorsal fins?
LSI occurs in all adult male orcas (and many females) in captivity; that is, 100\% of captive adult males have totally or partially collapsed dorsal fins. No captive display facilities, including SeaWorld, have conducted relevant research into this phenomenon.
Dolphins and whales are closely related. Orcas were given the name ‘killer whale’ by ancient sailors’ observations of groups of orcas hunting and preying on larger whale species.
What is the largest fin on an orcas?
Male Orcas have the largest dorsal fin of any marine mammal. It can get up to 6 feet tall. On females it’s a bit shorter and more curved. The dorsal fin acts like a keel, and each dorsal fin is unique for each Orca.
How many killer whales have collapsed fins?
