#blue angel nudibranch

Ocean alien - this mesmerizing creature is glaucus atlanticus, or the “blue dragon” nudibranch. Rather than crawl along the seafloor like other sea slugs however, these little dragons really do soar across the seas - those winglike appendages create surface tension that allows them to adhere to the underside of the water’s surface, with currents and wind patterns carrying them across large distances. Despite this grand way of living, g. atlanticus only reaches up to a few centimeters long!
