The testis and ovary of sea-urchin, Strongylocentrotus nudus, were collected separately by a microscopic operation. The differences of the palatability and the compositions of proximate and extractive constituents were studied. Both were delicious and the flavors resembled each other closely, but the ovary seemed to be delicately sweeter and more astringent. The proximate composition showed a slight difference between the two specimens. There was also an important feature in the amounts of free amino acids: relatively high levels of alanine, glutamic acid, and taurine were observed in the testis, and those of lysine, threonine, arginine, and isoleucine in the ovary. Higher yields of adenosine triphosphate, betaine, and creatine were obtained in the testis. No significant difference in organic acid composition could be found.
