Top 10 Ugliest Animals in the World: Blobfish

Blobfish – one of the weirdest animals in the world – is best known for its peculiar appearance like a tadpole fish, which is very suitable to help them to float on ocean floor. The most important features of this fish species are their soft and jelly-like body, rounded heads, large jaws, greyish or whitish pink color, pointed tails, loose skin, soft bones and fluffy pectoral fins.

Being around 12 inches in length with 20 pounds weight, blobfish are commonly found in the deep waters off the coasts of Australia and Tasmania. They move very easily at the depths of 2000 – 4000 ft, in fact, this huge pressure gives them their shape. However, if we brought them up on the surface, their appearance may change due to changes in pressure.

Unlike most fish, blobfish don’t have a swim bladder to control their buoyancy. This adaptation allows them to thrive in the extreme water pressure of the deep sea!

Decoding the Rankings

Our list of top 10 ugliest animals in the world is based on several factors such as their peculiar appearances, unique features, and how they’re perceived by the public. On the top, we put blobfish due to its jelly-like body along with soft bones. Next we chosen proboscis monkey which is mostly known for its extra-long nose. After it, aye-aye for its rodent-like teeth, naked mole-rat for its hairless skin and star-nosed mole for its peculiar nose were placed on their respective positions. Continuing the list, matamata turtle, vultures and marabou storks were enlisted due to the unique shell, wrinkled head and odd appearance respectively. Lastly, anglerfish finalized the list by its unnerving glow and fishing rod-like addition.


Among all the mammals, the naked mole-rat is often considered as the ugliest mammal due to its unusual look.

Blob fish is considered as one of the ugliest fish because it has very unusual appearance. However, different people give different opinions about the ugliest fish, depending upon the way they think.
