What is the ugliest fish in the world?

One of the creatures that inhabits quite unknown territory is the pink gelatinous animal known as the blob fish or drop fish (because of its curious appearance).

The blurfish (Psychrolutes marcidus ) is one of those somewhat unknown creatures because it lives in extreme areas of deep water. It normally inhabits the coasts of mainland Australia and Tasmania, but is elusive to humans. Rarely have we come across one of them in its natural environment, swimming at a depth of about 1,000 metres.

How is this fish?

It is unique in anatomy and design. This creature is about 30 centimeters long and weighs about 9 kilograms . It is pinkish gray in color; It has a thick head, with large eyes that allow good visibility in the dark. It has no muscles and its body is gelatinous, although robust, and with soft bones (flexible, similar to cartilage). And, unlike other fish, it doesn’t have a full backbone. He also has no teeth.

At the depths at which they live, deep-sea dwellers experience up to 120 times more pressure than on land, hence the extreme pressure of the deep sea provides structural support for their bodies. That’s why when you take it out of the water it has this picturesque aspect, because its body expands; it deflates and collapses, giving it its smudged appearance.

He doesn’t have a swim bladder.

Another reason it can reside so deep is that, unlike most ocean fish, this species does not have a gas-filled swim bladder (or buoyancy organ). That’s why this species can reside at such depths without succumbing to extreme pressure. The gelatinous mass that it has as a body, with a density somewhat lower than that of water, allows it to float along the seabed without spending energy swimming. When healthy and in its natural habitat, underwater cameras show its color to be closer to tan and gray than pink.

Raised as the ‘ world’s ugliest animal ‘ by the Ugly Animal Preservation Society , this fish eats small animals such as crustaceans, worms and snails. It is difficult to study it, since it lives in very deep environments and cannot survive when it is extracted from its natural environment. Of course, it is worth noting that inside the water it is not as unattractive as outside of it.

How long does he live?

Many things about him are unknown, such as what his longevity is. How long can you live? Scientists don’t know. According to the International Union for Conservation of Nature (IUCN), this omnivorous species is classified as critically endangered. It belongs to the genus Psychrolutes , which consists of 11 recognized species.

Not much is known about their reproductive habits, either. They lay large numbers of eggs – perhaps just over 80,000, of which about 1% will survive, according to estimates – and guard them in the nest until they hatch.

Because they live at such great depths, blobfish have no natural predators that we know of except humans who tend to catch them by accident when fishing for other species of fish.

Scientists originally classified the species in 1926, but since it cannot be observed in its natural habitat, due to the depths at which it lives, we do not know many details about it. The creatures that live in these conditions have to have specially adapted bodies that allow them to survive such pressure and darkness. As is your case.
