1. BLOB FISH
You might have never thought about their existence but they do exist. Not having any bone makes it look uglier. That is the reason they were once given the title of World’s Ugliest Animal. Blobfish have features as weird as their external structure. They live under 2000-4000 feet with extremely high pressure. While unusual pressure can kill most aquatic animals, it does not affect it. Blobfish uses its gelatinous mass to flow in the water. So, the lack of swim bladder acts as an advantage. They conserve their energy and are mostly found lethargic. But you will be surprised to learn that blobfish has been an inspiration for various pop music and art. A certain website ran an online poll and this animal turned up as No.1. No surprises here. If you have a blobfish in your aquarium, you will probably have very few visitors. Usually found on the coasts of Australia and New Zealand, this hideous creature is rarely encountered by humans, which is totally fine! They weigh a lot but they still float on water thanks to the gelatinous material it is made of, which is less dense than water.
The species can grow upto 12 inches in length and weighs approximately 12 inches in length and weighs approximately 20 pounds. Talking about the appearance, it has loose pink skin and they are covered with spines instead of scales. The body has a jelly-like the texture and it is the primary reason why it is named as the ugliest creature on planet Earth, however. like other fishes, it does not have a swim bladder because it can collapse in the atmosphere of huge pressure and can result in bursting of the body. It is not at all harmful for the humans and it does not have a teeth. It loves to spend his entire lifespan on the sea floor and does have any commercial use because it is not tasty.
