Description
Known to some as sea scorpions, Eurypterids are amphibious arthropods related to arachnids. Primeval and voracious, these predators range in size from relatively harmless, the size of a small dog, up to large ones the size of a cow. Regardless of their size, all share one thing in common: an aggressive attitude. Eurypterids lash out at anything that might be food, happily secure in their flat, stout carapace. Although quite at home in the shallow sea (or fresh-water lake), most eurypterids are capable of scuttling around on land and can exist out of water indefinitely.
There is a small amount of evidence that some species of eurypterids are poisonous, but all of these are of the small variety. Those stung by a poisonous eurypterid must make a saving throw against poison at +2 or die.
Pentecopterus is a fearsome sight to behold in the seas it prowls. The largest specimens can reach an impressive length of 5 feet 7 inches. Its segmented exoskeleton is dark and imposing, providing both protection and camouflage in the murky waters it calls home. Eight powerful legs, each tipped with sharp claws, propel it through the water with surprising speed and agility. Along its body, Pentecopterus bears a single pair of spines on the third segment of its body, a distinctive feature that sets it apart from its kin. Its chelicerae are short with a serrated edge, perfect for grasping and rending prey.
Pentecopterus inhabits shallow coastal regions and estuaries, lurking in the cloudy disturbed water.
