Onchidella floridana is a species of air-breathing sea slug, a shell-less marine pulmonate gastropod mollusk in the family Onchidiidae.
This species occurs in the Caribbean Sea and the Gulf of Mexico. And was once ubiquitous in and around the shallow waters - intertidal zones - of Bermuda. Never located on the rugged, storm-tossed Atlantic Ocean side of the Island. Observed, studied & photographed by graduate student(s) attending Marine Ecology Summer Program at Bermuda Biological Station in 1985.
