Abstract

The undulatory movements of the abdomen of H. pellucidula and H. siltalai larvae are being investigated in relation to water temperature and dissolved oxygen tension.

Recordings of undulatory activity show that periods of quiescence alternate with periods of continuous undulation. The time spent undulating and the rate of undulation both increase with rise in water temperature.

The difference between the oxygen uptake of anaesthetised and active larvae of H. pellucidula represents some 70–80% of active oxygen uptake. Estimates of the oxygen uptake per undulation are discussed.

The investigation is continuing.
