The materials that they are made out of are just a bit lighter than water, which allows them to float a bit above the seafloor. 13. What they do have though is a jelly-like flesh that has a lower density than water. But without this particular make-up, down at depth, it’d be dead. They don’t have muscles, and they don’t have a single bone in their body as well. 6. It also picks up slow-moving sea creatures such as sea slugs, snails, and sea urchins which have been found in the bellies of some dead blobfish examined by scientists. 5. The blobfish (Psychrolutes marcidus) is a foot-long pink fish found in the deep waters off the coasts of Australia and New Zealand.It has soft bones and few muscles and lacks a swim bladder, the gas-filled internal organ that allows most bony fish to control their ability to stay afloat in water. And they don’t need much muscle either. These include breathing with its gills, opening its mouth, and moving its fins slowly to navigate just above the ocean floor. So, up here, it’s saggy and droopy. Under their skin, blobfish have a thick layer of gelatinous flesh that floats outside their muscles. The blobfish or smooth-head blobfish is known as one of the ugliest fish in the world.Its scientific name is Psychrolutes marcidus and it’s found in the depths of the ocean. Without any muscles the blobfish is not a very active fish. They are related to the Blob Sculpin (Psychrolutes phrictus) species. Blobfish have no muscles! The blobfish doesn’t really have a skeleton, and it doesn’t really have any muscle. They can live at depths up to 2,700 feet below the surface of the water. The flesh of the blobfish is primarily a gelatinous mass with very fine, soft bones, which allows the fish to survive at high pressure and float above the sea floor at extreme depths, without expending much energy. So the blobfish is able to maintain its buoyancy due to its gelatinous masses. They don't have muscles to move and swim, they float around the bottom of the sea/ocean and just eat little creatures that pass by it One may also ask, do blobfish have brains? This method works well for the blobfish as it expends very little energy. The blobfish has no real skeleton, and little muscles. Whatever they try to eat, they simply swallow it as a whole because they don’t have any teeth to chew their food. For survival, the blobfish basically hangs out right above the ocean floor, moving its mouth to catch its food. Blobfish don’t have teeth. 4. 12. Known as bottom dwellers, blobfish do not venture much higher than just above the seafloor. Instead it just sits there swallowing any food matter that floats by. They Don’t have Bones or Much Muscle Mass. 1. Gelatinas have masses that are less than water, which allows the fish to float slightly above sea level without burning the body’s energy by swimming. One man tried to eat a blobfish Fish are known to withstand very high pressures because they do not have muscles … Their bodies don’t really need bones, because the crushing pressure of the depths give them all the support they need. 3. It seems as if it were a kind of monster from the depths. Blobfish look blobby because they are full of water. This also means that they don’t have any teeth! Its low muscle mass and usage have an added benefit that it uses very little energy in movement. This allows them to float just above the ocean floor. Its gelatinous texture gives it a very strange and curious appearance that makes it look horrendous.. The blobfish has retained just enough muscle, attached to its soft skeleton, to perform the basic function of living. Since it has very few muscles, it is believed to hover around the sea floor awaiting for food consisting of floating sea crustaceans, dead biomass from above, and larvae.
