Abstract
Spermatozoa of the purple sea urchin (Strongylocentrotus purpuratus) diluted 1:400 in sea water soln. containing 0.05M glycine remain virile for more than 20 hours in the dark at 13[degree]C. Untreated spermatozoa in the dark lose their viability in 1-3 hrs. Glycine also exhibited a strong protective effect on spermatozoa treated with visible light. Spermatozoa in sea water exposed to light failed to fertilize eggs after 5-10 min., while in glycine solns. they lost their viability only after exposures of more than an hr.Keywords
