Fig. 1. Tail lordosis induced by microgravity. Lordotic body shapes of tadpoles
exposed to microgravity during a spaceflight (MM, CM) or to simulated
1g-condition by centrifugation (CC) during a spaceflight. CM
differs from MM because these tadpoles were centrifuged at 1g
for 4 days, and thereafter exposed to microgravity for 5 days, while MM
tadpoles were exposed to microgravity for 9.2 days (observations from the
STS-84 mission in 1997). The numbers indicate the lordosis score with 1 weak,
2 medium, and 3 strong. 0 indicates normal body shape.
