Giant water spiders possessed a slight degree of intelligence. Because of this, creatures such as nixies were sometimes known to establish a relationship with then, often by means of offering food. But like any spider, they were liable to attack any creature that disturbed their home.
- Giant marine spiders
- A rare species of water spider that was larger than others and found only in saltwater environments.
Giant water spiders would build large nests amidst underwater vegetation that acted as a pocket of air. Any prey that was caught while out hunting would be dragged back to this lair, where they could safely cocoon them for later digestion.
These creatures were only known to inhabit freshwater lakes, though a rarely encountered sub-species lived in saltwater habitats.
In particular, giant water spiders were known to occasionally be found in the lakes of Cormanthor, the neighboring Moonsea region's lake of the same name, the River Ashaba, Dragon Reach, and the Marsh of Chelimber. Beneath the cold plains and Galena Mountains of the Vaasa region, they inhabited an Underdark cavern sacred to Kiaransalee known as the Vault of Gnashing Teeth.
