• Apron reef – short reef resembling a fringing reef, but more sloped; extending out and downward from a point or peninsular shore
• Bank reef – linear or semicircular shaped-outline, larger than a patch reef
• Ribbon reef – long, narrow, possibly winding reef, usually associated with an atoll lagoon
