The blobfish, or 'Psychrolutes marcidus', is a recently discovered deep-sea fish that has been labelled the 'ugliest animal in the world'. However, this perception is largely due to the decompression damage its jelly-like body experiences when removed from its natural high-pressure environment. Blobfish inhabit waters just above the seabed at depths of 600 to 4,000 feet, off the coasts of Australia, Tasmania, New Zealand and Tasmania. They have a unique anatomy, including a sparse skeleton and a lack of muscle, which has adapted to their deep-sea environment. So, do blobfish have muscles?
| Characteristics | Values |
|---|---|
| Muscles | Blobfish have minimal muscles. They have a special kind of muscle that lets them move in quick bursts to catch prey. |
| Movement | Blobfish move only when necessary. They have little muscle to move around and search for food, so they eat whatever floats into their mouths. |
| Habitat | Blobfish inhabit waters just above the sea bed at depths of 600 to 1,200 meters (2,000 to 3,900 feet) off the coasts of Australia, Tasmania, and New Zealand. |
| Anatomy | Blobfish have a sparse skeleton made of very weak bones. Their bodies are filled with water and fat, which protect them from surrounding pressure and enable them to move easily across the sand. |
| Buoyancy | Blobfish do not have a swim bladder, an organ that helps with buoyancy. Their bodies are slightly less dense than seawater, which helps them float above the seafloor. |

Blobfish have jelly-like bodies with very little muscle
Blobfish are deep-sea fish that inhabit waters just above the seabed at depths of 600 to 4,000 feet, off the coasts of mainland Australia, Tasmania, and New Zealand. They have jelly-like bodies with very little muscle. They were discovered in 2003 by marine ecologist Kerryn Parkinson while on an ocean expedition off New Zealand.
Blobfish have been described as the ugliest fish in the world. However, this stereotype is due to decompression damage to their jelly-like bodies when they are taken out of their natural high-pressure environment. Blobfish have a unique anatomy that enables them to thrive undersea. They have a sparse skeleton made of very weak bones, and instead of red muscle, they have an abundance of white muscle, which allows them to swim in short bursts to catch prey. Their soft tissue is filled with water and fat, which protects them from the surrounding pressure and enables them to move easily across the sand.
Blobfish have large black eyes, a large mouth, and a bulbous nose, with a globulous head that makes up 40% of their body mass. They can reach more than two feet in length, although they are typically one foot long on average. Blobfish lead lethargic lives, moving only when necessary. They are bottom-feeders and consume whatever flows into their mouths. Their diet includes crustaceans like crabs and lobsters, as well as sea urchins and mollusks.
The extreme pressure of the ocean depths, which can be up to 120 times higher than at the surface, holds the blobfish together. Blobfish look like a regular fish in their natural habitat. When they are brought to the surface, they encounter a rapid pressure drop, which causes their anatomy to turn into a gooey mess. This is why they appear so different from other fish.

They have a sparse skeleton made of weak bones
The blobfish is a deep-sea fish that inhabits waters just above the seabed at depths of 600 to 4,000 feet, off the coasts of mainland Australia, Tasmania, and New Zealand. They have been described as the ugliest fish in the world, but this perception is due to decompression damage to their jelly-like bodies when they are removed from their natural high-pressure environment. Blobfish have a sparse skeleton made of weak bones. Their soft tissue is filled with water and fat, which protects them from the extreme pressure of their deep-sea habitat. This pressure can be up to 120 times higher than at the surface, and it is this pressure that holds the blobfish together, giving it a recognisable fish shape.
Blobfish have little muscle, and their movement is limited to short bursts to catch prey. Their minimal skeleton and flesh filled with water are characteristic of deep-sea fish, enabling them to live in their harsh environment with minimal energy expenditure. They do not have a swim bladder, an air-filled organ that helps with buoyancy, which means they are adapted to life on the ocean floor. Instead, their jelly-like bodies help them float along the bottom of the ocean.
The extreme pressure of the ocean depths means that blobfish are difficult to study in their natural habitat. Most of our knowledge of blobfish comes from studying deceased specimens that have washed up on beaches or been caught in trawling nets. Blobfish are generally whitish or light grey, with large black eyes, a large mouth, and a bulbous nose. Their globulous head makes up 40% of their body mass, and they can reach over two feet in length.
Blobfish are members of the Psychrolutidae family, which includes fatheads, fathead sculpins, and tadpole sculpins. They are lethargic and slow-moving, preferring to rest and conserve energy. They are bottom-feeders, consuming whatever comes into their path, including crustaceans, sea urchins, and molluscs.

Blobfish are bottom-feeders and will eat almost anything that comes into their mouth
Blobfish are bottom-feeders that eat almost anything that comes into their mouths. They are often found in the dark, cold habitats of the Atlantic, Indian, and Pacific Oceans, between 1,970 and 3,940 feet deep. They have a varied diet, including crabs, lobsters, urchins, brittle stars, anemone, shellfish, sea pens, carrion, and marine snow. They are true generalists, and their diet is influenced by their deep-sea environment, where food is scarce. This lie-in-wait strategy is common in the deep sea, allowing blobfish to conserve energy by remaining at rest and feeding infrequently.
Blobfish have a distinctive appearance, with large black eyes, a large mouth, and a bulbous nose. They are tadpole-shaped with bulbous heads, large jaws, tapered tails, and feathery pectoral fins. Their bodies are primarily composed of gelatinous substances with little to no muscle, which makes them susceptible to deformation when brought to the surface. This jelly-like composition allows them to float just above the ocean floor with minimal energy expenditure. Blobfish have minimal skeletons, and their flesh is filled with water, enabling them to survive in the harsh deep-sea environment.
The extreme pressure of the ocean depths, up to 120 times higher than at the surface, holds blobfish together in their natural habitat. When hauled to the surface, they experience a rapid pressure drop, causing their anatomy to turn into a gooey mess. This distortion has earned them the title of the world's ugliest animal. However, in their natural habitat, blobfish resemble typical deep-sea-dwelling fish. They have no known natural predators and reproduce by laying large clutches of around 100,000 eggs.
Blobfish were discovered in 2003 off the coast of New Zealand and classified as a species in 1926. They are challenging to study in their natural environment due to the extreme depths they inhabit. Most of our knowledge about blobfish comes from deceased specimens found in trawling nets or washed up on beaches. They are considered extremely endangered, with an estimated worldwide population of around 420. Human activities such as deep-sea fishing and bottom trawling pose threats to blobfish populations.

They have little to no swim bladder, which controls buoyancy in other fish
Blobfish are deep-sea fish that inhabit waters just above the seabed at depths of 600 to 4,000 feet, off the coasts of mainland Australia, Tasmania, and New Zealand. They have been described as the world's ugliest animal, although this perception is largely due to decompression damage to their jelly-like bodies when removed from their natural high-pressure environment.
Blobfish have little to no swim bladder, an air-filled organ that helps other fish move around and stay buoyant. If a fish with a swim bladder is removed from its natural habitat, the volume of the gases in the air sac will expand with the lightening water pressure, potentially causing the bladder to expand to the point where it crushes the fish's other vital organs, killing it.
Blobfish, on the other hand, have bodies made up of a blobby substance with a density that is slightly lower than water, allowing them to float above the seafloor. This adaptation means that when a blobfish is brought into shallow waters, it doesn't die like other deep-sea fish; instead, its jelly-like body collapses into a gooey mess. Blobfish have little muscle, which, along with their sparse skeleton, contributes to their gelatinous appearance when they come to the surface.
Blobfish are generally whitish or light grey, with large black eyes, a large mouth, and a bulbous nose. Their heads are globulous and make up 40% of their body mass. They can reach lengths of over two feet, although they are typically around one foot long. Blobfish are lethargic and move only when necessary, conserving energy by going days without eating. They are bottom-feeders, consuming whatever flows into their mouths, including crustaceans, sea urchins, and molluscs.

Blobfish are white or light grey and can grow to be over two feet long
Blobfish are generally white or light grey in colour, although they have also been described as pinkish-grey. They have large black eyes, a large mouth, and a bulbous nose, with a globulous head that makes up 40% of their body mass. They have little to no skeleton and very little muscle, which gives them a gelatinous appearance. They are deep-sea fish, which means they have a high water and fat content that helps them withstand the high pressure of their environment. Blobfish inhabit waters just above the seabed at depths of 600 to 1,200 meters (2,000 to 3,900 feet). They can be found off the coasts of mainland Australia, New Zealand, and Tasmania, as well as in the Atlantic, Indian, and Pacific Oceans.
The blobfish's unique physiology allows it to survive in extreme conditions. They do not have a swim bladder like many other fish, as this would implode under the extreme pressure of their deep-sea habitat. Instead, their soft bodies have a slightly lower density than water, allowing them to float above the seafloor. This also helps them to conserve energy, as they do not have to expend much energy to move along the ocean floor in search of food. Blobfish are bottom-feeders and will consume almost anything that comes their way, including crustaceans, sea urchins, mollusks, and carrion that falls to the seafloor.
Blobfish are typically around one foot long, but they can grow to be over two feet in length. Their reproduction rate is slow, and they have a slow rate of growth and maturation. It is estimated that only about 1% of blobfish survive to adulthood, and they are considered extremely endangered by many. Blobfish may have a lifespan of over 100 years, although their precise lifespan is unknown. They are believed to be long-lived due to their slow growth rate and lack of predators.
The blobfish was first discovered in 2003 by marine ecologist Kerryn Parkinson during an ocean expedition off the coast of New Zealand. They have been described as the ugliest fish in the world, but this perception is due to decompression damage to their jelly-like bodies when they are removed from their natural high-pressure environment. In their natural habitat, blobfish look like regular fish, with tadpole-shaped bodies, broad, flat heads, large jaws, tapered tails, and feathery pectoral fins.

Frequently asked questions
Blobfish have very little muscle. Instead of red muscle, they have an abundance of white muscle, which allows them to swim in short bursts to catch prey.
Blobfish have minimal muscle due to their deep-sea environment. They live in extremely high-pressure environments, which can be up to 120 times higher than at the surface. This high pressure means they don't need muscle to move around and search for food, so they eat whatever floats into their mouths.
Blobfish have a sparse skeleton made of very weak bones, as strong bones take energy to develop. Their flesh is filled with water and fat, which protects them from surrounding pressure and enables them to move easily across the ocean floor.
