Blobfish spend most of their time floating, waiting for food to come to them. They eat sea urchins, mollusks, and shellfish.
They are rarely seen by humans in their natural habitat. The body of a blobfish is about 30 centimeters (1 foot) long.
They have large, leaflike pectoral and some species are covered with soft spines. Such fish can be found between 100 metres to 1,600 metres in depth. They are found in the Pacific Ocean, Indian Ocean, and Atlantic Ocean.
The Psychrolutes Marcidus, more commonly known as the Blobfish, comes from the family of Psychrolutidae, an obscure family of fish (obscure probably because we don’t see them very often). This fish family is characterized by large heads and bodies that taper back into small, flat tails.
Further, the blobfish may be one of nature’s most energy-frugal fishes. Its flesh is only slightly denser than water, so it does not expend any energy on swimming.
The fish, which shrivels up when exposed to air, is completely inedible. Experts worry that the blobfish may soon face extinction.
Blobfish arecaught by bottom trawling with nets as bycatch. Trawling in the waters off Australia may threaten the blobfish in what may be its only habitat and is currently facing extinction due to deep-sea fishing.
Blobfish live at depths where the pressure is 80 times higher then normal sea level.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 using energy to swim. Its lack of muscle is not a disadvantage as it primarily swallows prey that floats in front of it.
Mr Blobby is psychrolutid fish (family Psychrolutidae). Fishes in this family are called the blobfishes or fathead sculpins. They are found in marine waters of the Atlantic, Indian and Pacific Oceans at depths between 100 m and 2800 m.
The scientists and crew on board the RV Tangaroa affectionately called this fish 'Mr Blobby'. The fish's body is flabby and not adapted to be out of water!
