  • Why does a killer whale’s fin bend in captivity?
    The typically upright dorsal fin of a killer whale (Orcinus orca) often droops or bends in captivity due to a complex interplay of factors including reduced activity, altered water conditions, and genetic predisposition This article explores the scientific consensus behind this phenomenon
  • Why Do Orca Fins Bend in Captivity? - Collapsed Dorsal Fin in Killer Whales
    While a collapsed dorsal fin does occur in wild killer whales, it is uncommon Most captive orcas have a bent dorsal fin and the reasons why affect their welfare
  • SeaWorld Fact Check - Dorsal Fin Collapse
    Captivity has a range of inherent undesirable problems for orcas, including but not limited to aspects that may affect the upright position of the dorsal fin This “loss of structural integrity” (LSI) can result in partial or total collapse of the dorsal fin
  • Why do captive killer whales have drooping dorsal fins?
    The fins are supported by a tough protein called collagen, and one possibility is that, because captive animals spend more time at the surface, the protein is exposed to higher temperatures, which degrades its structure

  • Orcas in Captivity - Dolphin Project

  • Why Do Orcas’ Dorsal Fins Collapse in Captivity?
    Explore the physical and environmental reasons why the orca’s unique, non-bony dorsal fin structure fails almost exclusively in captivity
  • Why Are Killer Whales’ Dorsal Fins Floppy In Captivity? - LBC
    Answer: The reason the dorsal fins of killer whales are floppy in captivity is because they’re depressed and anxious Humans stoop and sag when they aren’t happy, and stand upright when they are, so it applies to animals too
