scud

I scudded like an autumn leaf, grappling with thin air.

The team looked at three types of freshwater animals -- two species of gammarid, or "scud," which is a small freshwater crustacean; one freshwater snail; and three aquatic insect species.

Fighter jets scudded over the horizon and a stray bomb landed nearby, killing members of a family in their home, they said.

But in summer the view from the opposite side is equally spectacular: the approach of moisture-laden monsoon clouds, scudding across the sky.

The sky was full of low scudding clouds when I landed in early December.
