The animal world is full of predators and nightmarish creepy-crawlies, but there are a few frightening-looking creatures that don't deserve such a fearsome reputation. Some of these animals look scary based on their massive size, while others have sharp teeth or fangs. However, all of these animals are mostly harmless to humans — as long as you don't catch them by surprise.

Perhaps due to their appearance, these gentle, harmless animals are often killed because of a local superstition that they are harbingers of death. Aye-ayes have a number of unusual traits, including a long, bony, witch-like middle finger that these peaceful, nocturnal foragers use to pry insects and grubs from tree trunks.

Unlike other carnivorous species of sharks, basking sharks are filter feeders. They prefer the taste of zooplankton and couldn't chomp down on you if they wanted to. The basking shark is endangered, so be sure to admire the beauty of these elegant beasts if you encounter one in the ocean.

But they typically prefer to feed on cattle, goats, and sometimes birds. Vampire bats don’t suck the blood of their prey, they use their teeth to make a tiny incision in the skin of their victim. While human bites are uncommon, they can carry infections and disease, including rabies.

But they're completely harmless — as long as you're alive and kicking. These scavengers have sharp beaks and razor-like talons, but they don't use these tools to kill prey. When food is scarce, vultures will occasionally prey upon a sick or weak animal, but they most often feed on carrion.

One of the largest species of spiders in the world, the goliath birdeater earned its name from a 1705 copper engraving that showed the spider eating a hummingbird. Despite the goliath birdeater's appearance, the size of its fangs, and its reputation, this spider prefers to dine on snakes, lizards, and insects and is only likely to injure a human if provoked.

As a result, these critically endangered beasts are often thought to be man-eaters, just like their crocodilian cousins. In reality, the gharial's thin jaws are fragile and incapable of consuming a large animal. Better adapted for hunting small fish, frogs, and insects, gharials prefer to avoid people entirely.

They can grow to be up to six inches long and can run as fast as 10 miles per hour. However, these hunter spiders do not possess poison, and, contrary to urban legend, they do not attack humans.

8 of 10 Milk Snake Matt Jeppson / Shutterstock These innocent serpents are famous for their biomimicry; they closely resemble the highly venomous coral snake. The most important difference between the two is that milk snakes are completely harmless to humans. But before you try to handle a colorful striped snake, remember this handy mnemonic: "red next to black is a friend of Jack; red next to yellow will kill a fellow."

9 of 10 Giant African Millipede Bjørn Christian Tørrissen / Wikimedia Commons / CC BY-SA 3.0 It's hard to imagine anyone cuddling up to this nocturnal monster, one of the largest millipedes in the world. Giant African millipedes can grow up to 12 inches long, can be nearly 4 inches thick, and have 300 to 400 legs. They can also live as long as 7 years, and despite their goosebump-inducing appearance, this oversized millipede is harmless; it feeds primarily on dead and decaying trees and plants.
