The largest of the living scorpions, which are arachnids (like Spiders) and not insects, is probably Heterometrus swammerdami. Specimens have been found that are some 9 inches (23 cm) in length. The Bombay Natural History Society is said to hold a specimen of which measures some 9.75 inches (24.7cm) in length. The largest scorpions that ever lived on earth are thought to be sea scoprions that reached some 3 meters in length. Over a hundred fossil scorpion species are known, and many are much larger than the living members of this group of creatures. The male Hadogenes troglobyte has been measured to a length of 8.5 inches (21 cm). Pandinus and Heterometrus (both about 7 inches or approx. 17.5cm) are most likely the heaviest at a bit over 30 grams.The biggest scorpion ever recorded was 3 metres long and 2 metres tall in Hull East Yorkshire.
