appearing to be some seaweed gently swaying under water, this is actually an above-water decorative grass (green foxtail) that has those fuzzy tops resembling caterpillars. this is a closeup shot (capturing 0.1 x 0.16 inches) of the seeds and fuzzies that dance in the wind atop this tall grass. the seeds can be seen as large light-green pods with dark-green stripes (like a melon), and the fuzzy strands can be seen in light-green branching off the main stem in the middle, and eventually fade to brown as they reach their end.
