The egg capsules of Hemifuscus pugilinus collected fromthe Pondicherry, South east coast of India. The free amino acid samples weremade fromthe egg capsules and then subjected to free amino acid analysis quantitatively by HPLC. Fifteen free amino acids have been determined in the egg capsules of H. pugilinus. The essential amino acids were isoleusine, leucine, lysine,methionine, phenylalanine, threonine, valine and histidine and while the non-essential amino acidswere alanine, aspartic acid, arginine, glutamic acid, glycine, serine and tyrosine, respectively. Glutamic acid is of higher concentration whereas valine were detected very less in concentration in the egg capsules. The total concentration of free amino acid exhibit in the egg capsules of H. pugilinus was low as it serves potential nutrients for embryos.
