From Wikipedia, the free encyclopedia
Psychrolutes marcidus, the smooth-head blobfish,[1] or simply the blobfish,[1] is a deep-sea fish of the family Psychrolutidae. It inhabits the deep waters off the coasts of mainland Australia and Tasmania, as well as the waters of New Zealand.[2]

Blobfish are typically shorter than 30 cm (12 in). They live at depths between 600 and 1,200 m (2,000 and 3,900 ft), where the pressure is 60 to 120 times greater than that at sea level, which would likely make gas bladders inefficient for maintaining buoyancy.[2] Instead, the flesh of the blobfish is primarily a gelatinous mass with a density slightly less than that of water; this allows the fish to float above the sea floor without expending energy on swimming. The blobfish has a relative lack of muscle, but this is not a disadvantage, as its main food source is edible matter that floats in front of it, such as deep-ocean crustaceans.[3]
