What is a blobfish?

Blobfish are usually associated with the species Psychrolutes marcidus, found off the coasts of Australia and New Zealand. Their bodies are adapted to deep water, where high pressure and low energy use are more important than a streamlined shape. When brought rapidly to the surface, the drop in pressure makes the fish look distorted and saggy, which created its internet-famous appearance. In its natural habitat, it looks much more like a normal fish than the cartoonish image people often share.
