Why does a viperfish often suffer damage when brought to the surface?

Answer

Its anatomy is optimized for high-pressure consistency

The viperfish is biologically and physically optimized for the intense, constant pressure found at depths of around 1,000 meters. Its internal anatomy and skeletal structures have evolved specifically to thrive under these conditions. When brought to the surface in a deep-sea trawl, the rapid and drastic reduction in pressure causes catastrophic structural failure, often leading to the fish appearing severely damaged or inflated. This fragility serves as an indirect measure of how successfully the species has adapted to its deep-sea niche.
