Pteropod: The Sea Butterfly - A Delicate Planktonic Mollusk #3607191 (License: Personal Use)

This image captures a pteropod-a pelagic gastropod mollusk-floating in open ocean waters. Its transparent body reveals internal structures, including a calcareous spiral shell and brownish digestive gland. The wing-like parapodia, lined with orange-brown spots, propel it through the water like a tiny butterfly.

Used in marine biology education, ocean conservation articles, and climate change discussions (as pteropods are sensitive to ocean acidification). Targets users seeking scientific visuals or ecological insights.
