Bearing, producing, or characterized by barnacles or similar crustacean attachments; covered with or containing anatifa.
From Latin anatifa 'barnacle' plus -ferous 'bearing/producing,' following the Latin adjectival pattern. The -ferous suffix appears in many English scientific terms.
Old wooden ships described as anatiferous would eventually become so encrusted that they'd rot from the inside out—the damage was as harmful as the drag.
