However, as the results of previous space flight experiments, it was suggested that hatched tadpoles in space had failed to inflate their lungs in a timely fashion because of difficulties to find air position in microgravity. To resolve this serious problem, parabolic flight tests have been performed to examine whether Xenopus tadpoles recognize the air/water interface by the illuminance direction as a substitutional cue for the gravity. The test results showed that it was possible for Xenopus tadpoles to recognize air/water interface and to breathe air in microgravity by controlling the air position stable and setting the illuminance under the same direction of the air., 資料番号: AA0046917020}, pages = {61--63}, publisher = {宇宙航空研究開発機構宇宙科学研究本部, Institute of Space and Astronautical Science, Japan Aerospace Exploration Agency (JAXA/ISAS)}, title = {微小重力環境で両生類は空気の位置を認識できるか}, year = {2004} }
