The blobfish, scientifically known as Psychrolutes marcidus, is a peculiar creature that resides in the deep waters off the coasts of Australia and Tasmania. It has gained quite a reputation for its unique appearance, often being referred to as the "world's ugliest fish." Despite its unappealing appearance, the blobfish is an intriguing creature with several remarkable adaptations that allow it to survive in its harsh deep-sea habitat. In this article, we will explore the fascinating features and characteristics of the blobfish.
Appearance and Habitat
The blobfish has a gelatinous and squishy appearance, with a droopy, saggy face that lacks any defined muscle structure. This unique appearance is a result of the blobfish's adaptation to the high-pressure environment of the deep sea. At depths of around 2,000 to 4,000 feet (600 to 1,200 meters), where the blobfish resides, the pressure is several times greater than at sea level. The blobfish's soft and flabby body helps it withstand these extreme pressures without being crushed.
The habitat of the blobfish is characterized by cold temperatures and limited food availability. It resides in the abyssal zone, which is the deepest part of the ocean. Due to its habitat, the blobfish has evolved to be a slow-moving and sedentary creature. It primarily stays close to the seafloor, using its gelatinous body to float just above the substrate and conserve energy.
Feeding Behavior and Diet
Blobfish are opportunistic feeders, meaning they will consume whatever food source is available to them. Their diet mainly consists of crustaceans, mollusks, and small fish that live near the seafloor. The blobfish's lack of muscles and sluggish movement make it a less active predator. Instead, it relies on its wide mouth and loose skin to engulf prey that happens to swim or float nearby.
Adaptations to Deep-Sea Environment
As mentioned earlier, the blobfish possesses several adaptations that allow it to thrive in the deep-sea environment. Besides its gelatinous body, which helps it withstand high pressure, the blobfish has a low-density flesh, which allows it to float just above the seafloor without expending much energy. This enables the blobfish to conserve energy and wait for potential prey to come within reach.
Furthermore, the blobfish lacks a swim bladder, an organ found in most fish that helps them control their buoyancy. Without a swim bladder, the blobfish is unable to actively control its vertical position in the water column. Instead, it relies on its gelatinous body and the surrounding water pressure to remain at an optimal depth.
Conservation Status and Threats
The blobfish is currently listed as "vulnerable" by the International Union for Conservation of Nature (IUCN). Its habitat is being threatened by various human activities, such as deep-sea trawling and bottom trawling. These destructive fishing practices can cause damage to the seafloor, potentially destroying the blobfish's habitat and disrupting its food sources.
Misconceptions and Popular Culture
Despite its unique appearance, the popular image of the blobfish that circulates on the internet is often misleading. Due to the drastic change in pressure when brought to the surface, the blobfish's gelatinous body loses its shape, resulting in a more exaggerated and less appealing appearance. In its natural habitat, the blobfish looks quite different, with its features being more proportionate.
The blobfish has gained popularity in recent years, becoming somewhat of an internet sensation. Its unusual appearance has led to its inclusion in various memes, cartoons, and even as a mascot for certain organizations. However, it is important to appreciate the blobfish for its unique adaptations and ecological significance rather than just its appearance.
Interesting facts about blogfish
1. They were voted the worlds ugliest animal in a 2013 online poll.
When the Ugly Animal Preservation Society needed a new mascot, they decided to put it to public vote. The blobfish was resoundingly named as the ugliest animal alive with 795 votes of 3,000, beating the proboscis monkey, the aquatic scrotum frog, and pubic lice for the top spot ‘honour’. However, the popular ‘ugly stereotype’ is rather misleading.
2. The blobfish actually looks like a completely normal fish in its usual environment.
At deep-sea, they look like a typical bony fish. This pressured environment provides their gelatinous body mass with structural shape.
The exclusive photo below was supplied to Fact Animal from the Newcastle University research team, and was taken 1562m to the north of New Zealand on an expediation by Dr Alan Jamieson, a senior lecturer and marine ecology expert, specialising in deep and extreme environments.
When blobfish are dragged to the surface out of their natural environment in bottom trawling nets, they appear bulbous and gelatinous without water pressure to hold their shape.
Dr. Thom Linley from the Newcastle University research team spoke to Fact Animal on the myth of the ‘ugly blobfish’.
3. Blobfish was first discovered in 2003, and immediately given it’s name.
Yes, it’s real name is ‘Blobfish’, it’s not a nickname. The very first blobfish ever found was nicknamed ‘Mr. Blobby’ by scientists and crew after being trawled during the NORFANZ expedition, on the Norfolk Ridge, north-west of New Zealand.
4. Blobfish live in an extreme pressure environment and experience up to 120 times the pressure as on dry land.
At this depth comparatively, human organs would be crushed under the sheer weight of pressure.
5. The blobfish has no real skeleton, and little muscles.
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.
6. They are related to the Blob Sculpin (Psychrolutes phrictus) species.
Recording blobfish on camera has proved to be difficult, and while still rare, the related blob sculpin fish has been been filmed more recently on the bottom of the ocean.
7. Blobfish do not have a swim bladder.
Unlike most fish, deep sea fish do not have air-filled cavitites, which act as buoyancy and help with movement. They would collapse under sheer pressure at the depths they live. They rely on their jelly like flesh to provide the required support instead.
8. Blobfish don’t spend much energy moving around.
They don’t actively hunt, due to their lack of muscles. As their jelly-like mass gives them a density lower than water at such deep pressures.
9. Blobfish have no teeth.
Blobfish don’t bite, they have no teeth and very few humans will ever come into contact with them. They float around above the sea floor hovering up microscopic bacteria and sea creatures that appear.
10. Their only predators are thought to be human, with accidental capture in deep sea trawling nets.
The rapid change in pressure is fatal for the blobfish, which is built for the high pressure deep sea environment only. They die out of the water instantly.
11. Blobfish are not considered a delicacy.
They never make it to the dinner plate, unlike a lot of fish. This is mainly because they are very rare and there are far simpler fish to catch.
12. Nobody has ever documented a living Blobfish.
Due to their extreme environment, humans have not been able to document them properly in the wild. Only a couple of rare underwater pictures have ever been captured. Nearly everything we know is based upon dead blobfish discovered in trawling nets.
Conclusion
In conclusion, the blobfish is a fascinating deep-sea creature that captivates the imagination with its unique appearance and remarkable adaptations to life in the extreme depths of the ocean. Despite their blob-like appearance and seeming vulnerability, blobfish are resilient inhabitants of the deep sea, perfectly adapted to survive in high-pressure environments where few other species can thrive. As efforts to conserve their habitat and mitigate the impacts of human activity continue, the blobfish serves as a reminder of the wonders and mysteries that lie beneath the ocean's surface, inspiring curiosity and appreciation for the incredible diversity of marine life.
