Megalograptus strikes a menacing figure, ranging from 1 foot 7 inches to 2 feet 7 inches in length, making it a fearsome predator. Its segmented exoskeleton, dark and mottled, provides both protection and camouflage in the murky depths it calls home. Eight powerful legs propel it through the water with surprising agility, while its chelicerae, each measuring several inches in length, are adorned with sharp, serrated edges perfect for tearing through flesh and armor alike.

But perhaps the most terrifying aspect of megalograptus is its tail, tipped with a poisonous stinger capable of delivering a deadly dose of venom to anything unfortunate enough to cross its path. This venom paralyzes prey, unless a successful save vs. Poison is made, allowing the megalograptus a chance to feed on the subdued victim.

It prefers shallow coastal regions and estuaries, where the waters are rich with prey and competition for resources fierce.
