The blobfish (Psychrolutes marcidus) is a deep sea fish of the family Psychrolutidae. Inhabiting the deep waters off the coasts of mainland Australia and Tasmania,[1] it is rarely seen by humans.
Blobfish live at depths between 600–1,200 m (2,000–3,900 ft) where the pressure is several dozen times higher than at sea level, which would likely make gas bladders inefficient for maintaining buoyancy.[1] Instead, the flesh of the blobfish is primarily a gelatinous mass with a density slightly less than water; this allows the fish to float above the sea floor without expending energy on swimming. Its relative lack of muscle is not a disadvantage as it primarily swallows edible matter that floats in front of it. Blobfish eat invertebrates like crabs and sea pens.[citation needed]
Blobfish can be caught by bottom trawling with nets as bycatch. Such trawling in the waters off Australia may threaten the blobfish in what may be its only habitat.[2]
The blobfish is currently facing extinction due to deep-sea fishing or bottom trawling.[3]
