However, due to fishing practices such as ocean bottom trawling, than can get caught in the nets as bycatch.
Scientific Name: Psychrolutes marcidus; Classification: Actinopterygii; Family: Psychrolutidae; Habitat: Deep waters; Diet: Crabs, mollusks, sea pens; Weight: 20 pounds; Location: Australia, Tasmania, New Zealand; Colour: Pink; Predators: None; Length: Less than 12 inches There are no known natural predators of blobfish. However, the blobfish doesn't look that way in its natural habitat. The blobfish is one of the world's most recently identified creatures - and it's really ugly!
The dorsal fin of this fish has eight spines and about 20 sot rays, while the anal fin has no spines and 12 to 14 soft rays. What are the most venomous animals in the world?
It looks pretty much like a regular fish.
It received the named after being preserved in a 70% alcohol solution and currently resides in the Australian Museum’s Ichthyology Collection in Sydney. Having been accidentally caught during a research voyage off the coast of New Zealand in 2003, the blobfish (or specifically, smooth-head blobfish) is a very recent discovery. Sometimes, blobfish get caught in trawlers used to catch deep-sea favorites, such as orange roughy and various crustaceans in their natural environment. Therefore, they are considered extremely endangered by many. Other close species are the blob sculpin (Psychrolutes phrictus) and the western Australian sculpin is (Psychrolutes occiendentalis). There is much to learn about the blobfish. As their mouths are fairly large, they can consume bigger creatures such as sea pens, crabs, mollusks, and sea urchins. Their muscles are minimal too, which helps them survive in the crushing pressure of the deep underwater habitats where they are found.
Therefore, when the blobfish is brought out of the water, it is unable to adjust to the vastly different atmospheric pressure, resulting in a blob-like appearance. These fish are commonly known as fathead sculpins. Their entire body is only slightly denser than water. Instead, its body is jelly-like, with a density slightly lower than the water in which it lives.
This is most likely when they are the most vulnerable to other animals.
The reproductive activity consisted of groups of nests with approximately 100,000 eggs each. Residing in deep depths of the sea, they must survive in an environment where the water pressure is up to 80 times higher than normal sea level.
Psychrolutes marcidus. Blobfish, Psychrolutes marcidus, is a deep-sea fish that live on the ocean floor. Because blobfish are found only in a few areas of the world and at depths between 2,000 and 4,000 feet below the surface of the water, they are rarely encountered live.
Read about other weird and wonderful creatures in our blog series. When the sac is filled with air, the fish will float to the surface. Like many deep-sea fish, blobfish feed on invertebrates as well as carrion that falls to the seafloor. It's difficult to know how many blobfish there are in the world, but one popular estimate indicates that only about 420 blobfish exist worldwide. However, bringing blobfish to the surface is thought to be generally fatal to these creatures, even if they have been handled gently. Although scientists classified the species in 1926, the general public had never heard of the creature, only gaining popularity and attention after its capture due to its odd looks. Suddenly, you see an odd, smooth, foot-long lump amongst the chaos. Whether you’re a scientist, engineer, teacher, or science advocate, together we can be a united voice for scientific progress. Blobfish, Psychrolutes marcidus, is a deep-sea fish that live on the ocean floor.
The extreme pressure of the ocean depths, which can be up to 120 times higher than it is at the surface, holds the blobfish together.Blobfish look the way they do when they come to the surface because their anatomy has essentially adapted to their deep-sea habitat.
Little is known about this fish because of its small numbers and its remote habitat. Since blobfish do not have teeth, the prey would be swallowed whole. Since 2013, the blobfish has had the distinction of officially being the world's ugliest creature, according to an online poll conducted by the British-based Ugly Animal Preservation Society. The precise lifespan of blobfish is unknown, so scientists theorize that they are similar to other deepwater fish who usually live longer than their shallow-water counterparts.

These pink colored eggs in the nest were tended by brooding blobfish. Their diet includes sea crabs, sea urchins, shellfish and mollusks. They don't do much except bob along the ocean floor looking for food and consuming anything that comes in their path. Although blobfish are not edible, they are still being caught and dragged up with other marketable fish and invertebrates. The smooth-head blobfish takes on a much different shape when it is in its natural environment than when it is removed.
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. When they do, the blobfish would gulp them up. Blobfish lead lethargic lives, moving only when necessary.
Affectionately known as Mr Blobby, this blobfish resembles an inflatable character balloon that's lost a good amount of its helium. The natural habitat of the blobfish is in the deep sea off the coast of Australia and Tasmania. Since 2003, one fish has served as the (unfortunate-looking) face … Thus, they have adapted with a body structure consisting of mainly gelatinous mass and relative lack of muscle. However, that doesn't mean that the blobfish just sinks to the ocean bottom. This anatomical makeup also serves them well as they don't have to expend much energy to move along the ocean floor looking for food. The International Union for the Conservation of Nature (IUCN) has not studied them, so blobfish have not received an official conservation status.
Blobfish are well adapted to deep water and live near the bottom of the ocean. Some may live for over 100 years because of their slow rate of growth and lack of predators.No one knows exactly how blobfish mate, either. The blobfish are adapted to living in the deep sea where the water pressure is very high.
Another species, the blobfish sculpin, lives even deeper underwater at depths of up to 9,800 feet. They live in depths of 600–1200 meters underwater. They have little to no skeleton as well as little muscle, which explains their gelatinous look when they come to the surface.

Their gelatinous body is characterized by a large head that tapers back into a small flat tail.
You can learn more about how fish have evolved to have adaptations in keeping with their environments by building your own fish. Imagine sitting on the deck of a giant fishing trawler somewhere off the coast of Australia. The blobfish (Psychrolutes marcidus) is a foot-long pink fish found in the deep waters off the coasts of Australia and New Zealand.
The blobfish ( Psychrolutes marcidus) is a foot-long pink fish found in the deep waters off the coasts of Australia and New Zealand. This adaptive body structure allows them to float in the depths of the sea with very little energy expenditure. Fish Laboratory is reader-supported. Some scientists believe that blobfish don't tend to their nests, making them vulnerable to predators, although blobfish sculpin males and females have been observed sitting on nests after females have laid their eggs. However, that doesn't mean that the blobfish just sinks to the ocean bottom. The natural habitat of the blobfish is in the deep sea off the coast of Australia and Tasmania. Ecologist Kerryn Parkinson snapped a photo of a particularly bizarre-looking pink fish among their discovery. Blobfish sculpin nests may contain as many as 100,000 eggs, but only an estimated 1% make it to adulthood.
Scientists have observed some blobfish nests adjacent to one another so that the parents can hover above and collectively protect the eggs. Blobfish don't have a skeleton, only a partial backbone. A lot of what we currently know about the blobfish is from the dead ones that are captured as bycatch in fishing nets.
It’s a squid! Their gelatinous body is characterized by a large head that tapers back into a small flat tail. The size of an adult blobfish is approximately 30 cm in length. Psychrolutes marcidus, better known as the blobfish, is a type of deep-sea fish discovered along with over 100 other species in a 2003 expedition off New Zealand.
Out of the water or in shallow water, it takes on a much uglier appearance.
And if you're curious about what makes things float, rather than sink, you can check out this lesson. As blobfish haven't been extensively studied or observed in the wild, no one knows how many there are in the world. Blobfish don't have swim bladders - the air-filled sacs that keep many different species of fish buoyant - because those sacs would collapse under the water pressure at the depths where blobfish live. Their gelatinous flesh, which is slightly less dense than seawater, helps them remain buoyant and prevents them from vomiting the contents of their stomachs. Out of the water or in shallow water, it takes on a much uglier appearance.
They are not very active, moving primarily to open their mouths when a source of food comes near them. As their skin is slightly less dense than seawater, it also helps prevent them from vomiting the contents of their stomachs.Little is known about the behavior of blobfish because it is difficult to view them in their natural habitat at the bottom of the ocean floor. However, when their bodies are no longer underwater at such severe pressures, their gelatinous bodies spread out, giving hem the appearance of a blob.
Their size varies across the Psychrolutidae family with smooth-head blobfish growing to 12 inches, while blobfish sculpins can grow up to 28 inches. These nests of eggs were located on deep sea plateaus, in rocky areas. Some scientists believe that the blobfish are highly endangered as their numbers may be declining due to commercial fishing. This story originally appeared on Science NetLinks. These fish are lazy and don't hunt, so if their surrounding habitat changes and their food source becomes unavailable, they could die. Thanks to that, it floats slightly above the floor of the ocean, where it waits for small crustaceans and other edible matter to pass by so it can suck them up for food.
These fish are commonly known as fathead sculpins. If blobfish had a swim bladder, it would immediately implode under pressure. The best-known blobfish specimen was found by a research vessel, NORFANZ, in 2003 and is preserved at the Australian Museum.
