| Abstract: | - 1.1. The light irradiation at examined wavelengths between 360 and 630 nm enhanced the respiratory rate in the presence of CO in sperm, as well as eggs, of the sea urchins, Anthocidaris crassispina and Hemicentrotus pulcherrimus, the starfish, Asterina pectinifera, and the echiuroid, Urechis unicinctus.
- 2.2. The maximum peaks of stimulating effects of light irradiation on CO-insensitive respiration were found at wavelengths of 430, 530 and 570 nm in sperm of these species.
- 3.3. The respiration in the presence of CO was insensitive to light irradiation in sperm and eggs of the oyster, Crassostrea gigas and the tunicate, Ciona intestinaris.
