VIDEO: Spider Battles Scorpion Twice Its Size

It’s a known fact that if one want to survive in the wild, one will have to fight!

We’ve all seen numerous fights between big mammals, felines and even reptiles.

But have you ever thought about insects? Ants? Bees? Spiders?

They have to fight for survival, too!

This video shows a brave spider battling a scorpion twice its size.

According to Live Science, a new scorpion species found fossilized in the rocks of a backyard could turn the scientific understanding of these stinging creatures on its head.

The fossils suggest that ancient scorpions crawled out of the seas and onto land earlier than thought. In fact, some of the oldest scorpions had the equipment needed to walk out of their watery habitats and onto land, the researchers said.

The fossils date back some 430 million to 433 million years, which makes them only slightly younger than the oldest known scorpions, which lived between 433 million and 438 million years ago.

The new species “is really important, because the combination of its features don’t appear in any other known scorpion,” said study leader Janet Waddington, an assistant curator of paleontology at the Royal Ontario Museum in Toronto.

The new species fell into Waddington’s hands almost by happenstance. Museum curators frequently get calls about fossils, most of which are run-of-the-mill, she told Live Science. But a woman who called about an “insect” in her backyard stone wall had something very exciting on her hands.

“When she showed me this fossil, I just about fell on the floor, it was so amazing,” Waddington said.

The fossil was no insect, but rather a scorpion — and a new species at that.

Over the years, more specimens trickled in, mostly from patio stones and rock quarries, and one from a mislabeled fossil at a national park on Canada’s Bruce Peninsula. Now, Waddington and her team have 11 examples of the new species, ranging in length from 1.1 inches (29 millimeters) to 6.5 inches (165 millimeters).

What made the animal, dubbed Eramoscorpius brucensis, so fascinating was its legs.

Previously, the earliest scorpion fossils found came from rocks that were originally deposited in the water, leading paleontologists to believe that the animals evolved on the seafloor, like crabs, and only later became landlubbers.

Ancient scorpions had legs like crabs, with a tarsus, or foot segment, that was longer than the segment preceding it. This arrangement, Waddington said, would have meant the creatures walked on their “tippy-toes,” such as crabs do today.

But E. brucensis was different. This species had a tarsus segment that was shorter than the segment before it, which would have made it possible for the animal to set its tarsus flat against the ground. In other words, this scorpion had feet.

“They could have walked on their feet, which is really important because it meant that they could have supported their own weight,” Waddington said. Without the need for water to buoy them up, the animals could have walked on land.

The fossils also show that the scorpions’ legs were solidly attached at the body, without the exaggerated “hinge” seen in scorpions that would have needed water to stay upright. What’s weird is that all the other features of these scorpions seem aquatic.
