摘要

水蚤Moina macrocopa (Straus, 1820)在21,500 × g离心10分钟后存活且未成球。在100,000 × g离心10分钟后，6个被试个体中有5个在微管中游泳。证实了M. macrocopa在自行车轮辐上的15ml离心管底部附近由于5 × g的离心力而发生。这表明M. macrocopa在管底部可以承受100,000 × g的条件。这是甲壳类动物能够承受极高重力的首次报道，这提示了M. macrocopa作为极端超重力新模型的潜在用途。

The water flea Moina macrocopa () (Cladocera: Daphniidae) withstands 100,000 × g in a centrifuge for 10 minutes

The water flea Moina macrocopa (Straus, 1820) survived and did not become pelleted when centrifuged at 21,500 × g for 10 minutes. Five out of six individuals tested swam in the microtube after being centrifuged at 100,000 × g for 10 minutes. It was confirmed that M. macrocopa occurred near the bottom of a 15 ml centrifuge tube on the spoke of a bicycle wheel due to the centrifugal force of 5 × g. This results suggests that M. macrocopa would have withstood conditions of 100,000 × g at the bottom of the tube. This is the first report that a crustacean can withstand extremely high gravitational forces, which prompts the potential use of M. macrocopa as a new model for extreme hypergravity.
