Generate a description of a serene scene outside a coastal area beach with organ pipe sponges and rockweed.
assistant
A rocky wall rising from the sandy bay floor curves gently from the southwest to the north. Clumps of knotted rockweed grow among the dark stones of the rock wall. A mass of pale organ pipe sponges gives the rocky wall an odd-mildewed appearance. Strong currents prevent swimming to the north or west.
