What Are the Scariest Animals on Earth?


OK, this one’s not exactly on Earth anymore. But the Heterodontosaur was one scary beast. We’ve seen some scary dinosaurs before, but this newly discovered small, fanged dinosaur species may be the most frightening. Scientists say that the 2-foot-long Heterodontosaur lived about 200 million years ago, was also covered in porcupine-like quill, had a blunt, bird-like beak, and huge hog-like fangs.

Goblin Shark

This rare species of deep-sea shark is called a “living fossil” because it’s the only extant representative of the 125 million-year-old Mitsukurinidae family. What makes this pink-skinned animal super scary is its profile, with a long snout full of jagged, nail-like teeth. It’s usually between 10 and 13 feet, and can be found living at depths greater than 330 feet.


This ancient order of arachnid chelicerate arthropods also known as whip spiders and tailless whip scorpions. Sure, they look scary, but they are actually harmless to humans, possessing no silk glands or venomous fangs. They rarely even bite, but have been known to grab fingers with their thorny pedipalps.

Deep Sea Anglerfish

You may remember this scary beast from Finding Nemo. Anglerfish are bony fish named for the way they lure food, by using a fleshy growth from its head as a lure.

Aye Aye Lumur

This lemur is native to Madagascar, and is probably the spookiest primate on Earth. It’s got rat-like teeth that grow forever, creepy thin fingers and beady yellow eyes. Fun fact: It’s also the world’s largest nocturnal primate.

Tube-Nosed Fruit Bat

This peculiar fruit bat species’ tubular nostrils give it a particularly goblin-like look. It also has unusual yellow spots on its ears and wings that add a grim vibe. Another cool note:The Tube-Nosed Fruit Bat was just one of the roughly 200 species encountered during two scientific expeditions to Papua New Guinea in 2009. That means no one had ever even heard of it before then!
