There are many weird and unusual animals in the world, and different sources list different ones. Here are some of the weirdest animals from various sources:

• Blobfish: This deep-sea fish has a gelatinous, droopy appearance and has adapted to the extreme pressures of the deep ocean.
• Aye-aye: This primate is often considered the strangest in the world due to its unusual appearance and eating habits. It has large ears, long middle fingers, and continuously growing incisors. Aye-ayes eat by tapping on trees to identify insects within the wood and then chewing into the tree with their incisors to access the bugs.
• Dumbo octopus: This octopus has ear-like fins that protrude from the sides of its head, giving it a cute appearance.
• Goblin shark: This deep-sea shark has a long, protruding snout and a pinkish coloration.
• Komondor dog: This large, white-colored Hungarian breed of livestock guardian dog has long, noticeably corded white fur that looks like dreadlocks or a mop.
• Platypus: This egg-laying mammal is semi-aquatic, nocturnal, and venomous. It has evolved electroreception to help locate prey, much like bats and sharks, but has almost 40,000 electroreceptors, providing incredible accuracy.
• Praya dubia: This giant siphonophore is not a fish, a whale, or a jellyfish, but is the unlikely giant of the underwater world. It is a colony of specialized organisms that work together to form a single entity.
• Saiga antelope: This antelope has a long, tubular snout that helps it filter out dust and warm up cold air in the winter.
• Thorny devil: This lizard has a spiky appearance and can change color to blend in with its surroundings.
• Uakari: This monkey has a bright red face and is found in the Amazon rainforest.

These are just a few examples of the many weird and unusual animals that exist in the world.
