Jellyfishes rely on drifting to eat.

水母利用漂流觅食。

Any of various jellyfishes of the class Cubozoa, having a cube-shaped medusa and a venomous, sometimes fatal sting.

任一种立方水母纲的水母，有立方形的身体和有毒，有时甚至能致命的螫刺。

Coelenterates typically having alternation of generations; hydroid phase is usually colonial giving rise to the medusoid phase by budding: hydras and jellyfishes.

以世代交替为特色的腔肠动物；通常群居的水螅阶段先于水母阶段；水螅和水母。

So where fishes use their eyes to spot planktonic prey, jellyfishes rely on body size—like the lion's mane jellyfish's 37-meter-long tentacles—to maximize their success.

所以，鱼类用眼睛来定位浮游生物，而水母依靠身体的尺寸，就像狮子的鬃毛一样，水母那长达37米的卷须，大大增加了它捕食成功的可能性。

Biologist jose Luis acuna of the University of Oviedo in Spain and his colleagues now suggest that jellyfishes are just as effective at mealtime as fishes when judged by the right measures.

西班牙奥维耶多大学的生物学家jose Luis acuna和他的同事发现，如果用合适的标准评判，在觅食期间，水母和鱼类一样厉害。
