Change of Ventilation on Feeding in the Pen shell Atrina (Servatrina) lischkeana

概要

論文の詳細を見る
In the pen shell, Atrina (Servatrina) lischkeana, ventilation and respiration were observed before and during feeding on micro algae, Chaetoceros glacilis (26, 519 cell/ml), measuring ventilation volume, oxygen utilization and amount of oxygen uptake. During feeding, the pen shell showed a 38-fold increase in ventilation volume due to a change in the ventilation from an intermittent patten to a continuous pattern. However, the amount of oxygen uptake increased only 1.2-fold. Before and during feeding, inhalation and exhalation of sea water from/into the mantle cavity was completely synchronized. Based on findings, the pen shell was supposed switching the ventilation in the feeding from an intermittent pattern to a continuous pattern.
