Why do the dorsal fins of killer whales fall over when they are in captivity?



  1. 0 Votes

    Killer whales in captive 
environments aren’t typically able to swim as much, as fast, or as straight as they can in their natural aquatic settings. This compromised level of exercise atrophies the connective 
tissue supporting the dorsal fin. The weight of the tall 
dorsal fin succumbs to gravity and falls-over.
