Millipede

 A fossilized millipede-like creature discovered in Scotland may represent the oldest-known land animal, a humble pioneer of terrestrial living 425 million years ago that helped pave the way for the throngs that would eventually inhabit Earth's dry parts.

Indeed, there are many ferocious creatures, both large and small, that are downright deadly. Here are some of the deadliest species in the world. You won’t believe the reason why some made it to this list!

Poison Dart Frogs

The time when our ancestors lived in an environment where they had to be on constant alert for fear of ending up prey to giant creatures has long gone. Our prehistoric ancestors would encounter the gigantic predators and try to survive.

This new species has to be the stuff of nightmares! Explorers in California have discovered a new species of creepy crawly which has 200 poison glands, four penises and 414 legs!
The ‘illacme tobini’ is a type of millipede and was found living in marble caves in the Sierra Nevada mountains.
