Abstract: 1. Four factors possibly aid attachment of Anthopleura elegantissima: Nematocysts, Substrate Conformation, Suction, and Adhesion. 2. The pedal disc mucus is significantly more cohesive a substance than sea water. 3. Optimal spacing of the pedal disc and mucus in substrate conformation and adhesion may play a dominant role in atttachment. 4. Large scale suction involving the pedal disc acting as a single raised cup does not occur. 5. The pausity of nematocysts in the pedal disc suggest that their role in the attachment can only be minor. 6. The chemical composition of the substrate may be involved in preferential attachment.
