Collapsed Dorsal Fins

100% of captive orcas have collapsed dorsal fins. Many scientists think it's caused by how much time the whales (dolphins, orcas are dolphins) above the water looking for more interesting things other then their dinky tanks. The pressure above water is different and the fins don't have harder developed fins.

But only 1% of wild orcas have collapsed dorsal fins. Maybe this is another reason SeaWorld should shut down. Comment your opinion below.
