The Sea Angel
SEA ANGEL Graceful swimmers, sea angels are beautiful to watch. A sea angel is a type of swimming snail. The muscular foot found in land snails has evolved into a pair of winglike structures called parapodia that are used for swimming in open water. Sea angels have a small, transparent, gelatinous body and do not have a shell. Sea angels have small wings compared to their relatives the sea butterflies, but they are very strong swimmers. Using a sculling motion, sea angels are able to swim fast . A creature that has been not known for a long period f time and is still not that famous but surely a beautiful one .
