Scorpions belong to the oldest land-based arachnides. Over 1800 different species are known to exist. Usually, they do not surpass the size of 10cm in length, but exceptions are know, such as the Emperor Scorpion (Pandinus imperator) which can grow up to become over 20cm in size. Scorpions mostly live at night and hide away during the day. They live mainly on insects but some species also feed on rodents and reptiles (lizards that are not big enough to be an opponent). Today humans threaten the existence of some species of scorpions. Take a look into the live of these amazing creatures!
