All monstrous spiders are aggressive predators.
Monstrous spiders come in two general types; hunters and web-spinners. Hunters rove about, while web spinners usually attempt to trap prey. Hunting spiders are speedier than their web-spinning counterparts and use higher speed numbers shown in parentheses.
Monstrous spiders of both types have roughly circular bodies surrounded by outspread legs: 3 feet wide* and 3 inches high.
*The number includes the spider's body and its legs; the actual body diameter is about a third of the total.
