What’s a 1/4 scorpion, 1/4 spider, 1/2 demon and can make 3 PhDs run screaming? The SOLIFUGID.
Solifugids can run up to 10 mph, grow to be about 5 inches long and have no problem chasing humans. Really fun when they take up residence in your storage hut and try to attack anyone that comes in. The stuff of nightmares, people.
