Four specimens of Actinopyga mauritiana collected on 27th September 1988 in Andaman waters south of Burmanalla near Port Blair, were left in the Aquarium on board FORV Sagar Sampada for observations. The surface temperature of the sea water was 25.0° C and the sea water in the Aquarium was 29.2°C. The higher temperature in the Aquarium triggered the male holothurians to spawn first followed by the female. The fertilized eggs developed only upto four-celled stage.
