Abstract: 1. The clotting mechanism of Balanus nubilus was found to be affected by calcium ion with a threshold value for induced clot formation of blood, diluted 1:3:1 with 10%EDTA and 3% NaCl respectively, falling between 0.025M and 0.1M calcium chloride. 2. The clotting mechanism of B. nubilus was also found to be affected by hydrogen ion concentration with an optimum value for clot formation at a pH value of approximately 6.7.
