To investigate the effects of gravity on morphogenesis at the cellular level, we have proposed a new experimental system with micromeres from sea urchin embryos [Izumi-Kurotani, A., Kiyomoto, M. Morphogenesis and gravity in a whole Amphibian Embry...

Four adult female Japanese newts, Cynops pyrrhogaster, were carried for 15 days aboard the orbiting space shuttle, Columbia, in July of 1994, as part of the Second International Microgravity Laboratory, IML-2 aquatic animal experiments. These prev...
We report here on the amplectic behavior of the Japanese treefrog (Hyla japonica) in microgravity. Treefrogs were exposed to 35 cycles of altered gravity, including approximate to 1.5 sec of G<0.1 every 3 min and 15 sec, on the FreeFall ''G.0''...

Japanese tree frogs (Hyla japonica) were flown to the space station MIR and spent eight days in orbit during December, 1990 /1/. Under microgravity, their postures and behaviors were observed and recorded. On the MIR, floating frogs stretched four...
We report here on the behavioral reaction of two reptiles to abrupt decreases in gravity. One striped rat snake, Elaphe quadrivirgata, and three striped-neck pond turtles, Mauremys japonica, were exposed to microgravity (mu-G) on parabolic flight,...
