Light Reactions of Littoral Gastropods


MOLLUSCAN behaviour has attracted the attention of many workers, and the literature contains several references to the homing ability and direction finding in various gastropods1. Light is acknowledged as an important factor in such mechanisms in numerous invertebrates, and recently the plane of polarization of light has been shown to be an operative factor in the orientation of Eupagurus bernhardus 2, the xipho-suran Limulus 3, some hymenopterous and lepidop-terous larvæ4, and various insects5.
