Abstract: 1. Movement of Cirriformia is randoma nd not extensive. 2. Cirriformia appear to move diagonally, and possibly horizontally. 3. The number of tentacles observed on the surface of the substrate in a given population seeems to represent only 35-55% of the total population during night and ay, and during all pphases of the tidal cycle except in dry sand during an extremely low tide when their tentacles are retracted. 4. Evidence indicates Cirriformia remain n the upper 8 inches of the substrate.
