Actually, the Dorsal fin collapses only while in captivity because it is their sign of being severely depressed. After the fin has collapsed, it will never have the full capability to regain its strength.Β
It's funny how the original caption said "about animal captivity or other issues unrelated to the photo." It is a beautiful photo no doubt, but keeping these beautiful animals in captivity for human entertainment is just sickening to me.Β

BananaHoss93 : The reason the dorsal fin collapses has to do with water pressure. Depression can't physically change a killer whale's body. Because there's no bone in the dorsal fin, it's not as solid as other parts of their body. Hope this clears things up.

Its a great picture I love Orcas ! But it makes me sad to see these beautiful creatures in captivity and what it does to them.. Like the dorsal fin being collapsed..Β

Thank you very much! I think the main cause of dorsal fin collapse is spending too much time at the surface. After orcas are moved, they seem to have more of a dorsal collapse (temporarily) due to being out of the water for a long time. It's possible that if a wild orca is spends more time at the surface than usual, the dorsal may lean or collapse. Of course, it is more common for captive orcas to be spending time at the surface.

Their dorsal fins collapse because in the wild they are constantly on the move in the currents and they have the water constantly pushing against it. In captivity there is no constant pressure from swimming great lengths in the ocean and so the fin will collapse.

It weirds me out so much that their top fin gets floppy

Thank you! The dorsal fin collapse is most likely caused by when orcas spend a lot of time at the surface. Recently moved orcas have temporarily shown more of a leaning dorsal after being out of the water for a long time, so I believe that's the main cause for it.
