“Ugly fish” is a term used to describe fish species that have unusual or unattractive physical features or characteristics. These fish are often considered unappealing or unsightly by humans due to their strange appearances, but they are usually well-adapted to their environments and have unique survival strategies.
Commonly referred to as the ugliest fish, it is important to note that beauty is subjective, and what one person may consider “ugly” may be viewed differently by another. So in this article, we will discuss the 12 Ugliest Fish in the World
Scientific name: Psychrolutes marcidus
The blobfish, a deep-sea fish, is sometimes referred to as the “ugliest fish in the world.” With a huge, bulbous head and a sagging, gelatinous body that resembles a sad face, it has a striking look.
The blobfish has a special adaption that makes it possible for it to live in the deep water despite its ugly look. The pressure is around 80 times greater than at the surface where the blobfish thrives, at depths of between 2,000 and 4,000 feet.
To cope with the extreme pressure, the blobfish has a body that is slightly less dense than the water around it, which allows it to float just above the seabed without expending too much energy. Its gelatinous body also helps it to absorb the pressure without being crushed.
Blobfish usually move slowly and eat small seabed crustaceans like crabs, lobsters, and other small fish. They are occasionally taken as bycatch in deep-sea trawling operations but are rarely purposely caught by fishermen.
However, overfishing and habitat degradation have made the blobfish a vulnerable species. They have become well-known online memes due to their peculiar look in recent years.
#2. Stargazer Fish
Scientific name: Uranoscopidae
The stargazer is a type of fish that is found in coastal waters around the world. It is known for its unusual appearance, with its eyes located on the top of its head and a large, upward-facing mouth. Despite its unique features, the stargazer is not a particularly well-known or popular fish.
Stargazers are often ambush predators that wait for food to approach while hidden in the sand or mud. The stargazer may swiftly clamp its jaws shut, swallowing the prey whole, when a possible meal swims above. They are also known to shock their victim with an electric organ before devouring it.
Although the stargazer is typically not thought to pose a hazard to people, it may be harmful to fishermen. Under its gills, the stargazer contains two poisonous spines that, if handled incorrectly, can inflict severe wounds.
Unfortunately, some species of stargazers are threatened by overfishing and habitat destruction. In some parts of the world, they are considered a delicacy and are caught for food. In addition, coastal development and pollution can also threaten their habitat.
#3. Humpback Anglerfish
Scientific name: Melanocetus johnsonii
Next on the list of the world’s ugliest fish is the humpback angler fish. It is a deep-sea fish known for its unusual appearance and hunting strategy. A long, whip-like appendage protrudes from the top of the female of the species’ head, and her body is distinctively bulbous. This appendage is coated with bioluminescent bacteria that draw prey.
When a potential meal is attracted to the light, the anglerfish can quickly snap its large mouth shut, swallowing the prey whole. The male of the species is much smaller than the female and lacks the distinctive appendage.
Humpback anglerfish uses its sense of smell to find a female and then bites onto her skin, eventually fusing with her body and becoming little more than a parasitic appendage.
Across the world, humpback anglerfish may be found in seas that are 1,500 to 3,000 meters deep. They are rarely observed by people because of their isolated environment and nocturnal behavior. They are, however, occasionally taken as bycatch in deep-sea fishing operations.
#4. Gulper Eel
