Abstract
The respiratory level of sea urchin eggs was measured before and after fertilization, using three Japanese species, Pseudocentrotus depressus, Hemicentrotus pulcherrimus and Anthocidaris crassispina. The rate of oxygen uptake of unfertilized eggs is low even immediately after shedding, and it remains constant for more than three hours. Upon fertilization, the rate of oxygen uptake of the eggs increases sharply, and the increase may occur under natural conditions.Keywords
