We humans weren't the only life-forms to be affected by the Great American Eclipse on Monday.
Tiny marine creatures known as zooplankton got all mixed up as the sunlight grew increasingly dim along the path of totality.
One hour before the sky went dark, the gradual change in light caused the confused little critters to begin swimming up the water column to start their nighttime feeding routine.
As soon as totality was over and the light levels began to return to normal, however, they realized their mistake and made their way back to the safety of deeper, darker waters.
"They didn't make it all the way up because the eclipse is only so long," said
