The tube of the coral worm ranges from 2 feet to 8 feet in diameter, stands from 2 feet to 20 feet tall, and looks like the precious pink, red-orange, or white variety. The worm itself has a long, black, sluglike body that exactly fits the diameter of the coral tube.
When prey approaches the coral reef, the worms dart out to their full length to attack the prey. Their mouths are lined with rough, bony plates able to grind coral or bite through a ship hull or armor. Their damage is based on their size, 1d4 per Hit Die, so a 4 HD creature inflicts 4d4 points of damage. If threatened, the coral worm can retreat into its tube, safe from all but the most persistent predator. Coral worms attack most creatures, but some types of lampreys and eels live with them and feed upon the scraps they leave.
The coral worm’s tube is covered with razor sharp ridges, 4 to 6 inches high and running several feet. Anyone coming into contact with these suffers 1d10 points of damage. The inside surface of the coral tube is pearly smooth.Coral worms might abandon their protective coral (where they are AC 0) to attack boats or swimmers. They move slowly (MV 3) and are only AC 8 when exposed.The coral tubes have no monetary value, but in a marine environment they are invaluable natural dwellings used by many creatures after the original worm has abandoned them.
