Abstract

The chemosensory detection of prey by the freshwater leech Nephelopsis obscura (Erpobdellidae) was investigated in the laboratory. Without direct tactile contact N. obscura of all three size classes tested were unable to detect and react to any of the prey types (Gammarus lacustris, Chironomus sp., Tubifex sp) or prey conditions (live, asphyxiated, homogenate) tested. The length of the starvation period (0–56 days) did not affect these results, nor did it increase activity. N. obscura thus appears to be an opportunistic wanderer rather than a stalker-hunter.
