You may come upon sheets of seaweed drying along the shoreline. Merfolk weave a crude kind of fabric from it, called seaweed cloth, that is used for garments, rope, and even baskets. Merfolk tools are made from bone, discarded land glass, or the sharp teeth of sharks, but never iron.
Explanation:
Merfolk are water faeries who appear in Beyond the Spiderwick Chronicles. As stunningly gorgeous as they are dangerous, merfolk live in loosely structured kingdoms deep in the sea, but occasionally their natural curiosity causes them to near the shore. Although usually seen at night out on the jetties or even sometimes on the soft sand of the beaches, they have been spotted in daylight, resting on rocky outcroppings. They have also been found trapped in tidal pools when the sea changes.
