pteropod



Pteropods are gastropods (ex: snails) with a reduced or absent shell and spend their entire lives in the water column of the oceans. They get their name from the modification of the typical crawling snail foot into flapping wings (“ptero” = wing, “pod” = foot). 
All species are quite small, typically a few centimeters long, but they are very numerous, so form an important part of the ocean food-web.
