Abstract

Incorporation of activated charcoal into the agar enhanced the accuracy of phototaxis by slugs two- or threefold. This was due to absorption of stray light rather than adsorption of a phototaxis-impairing chemical. The presence of charcoal had no effect on thermotaxis, the critical cell density at which phototaxis and thermotaxis become impaired, Slug Turning Factor (STF) interference with phototaxis, or chemotaxis by slugs in STF gradients. Activated charcoal in the agar had other effects on which may be chemical in nature.
