9. Motile invertebrates The total abundance of motile invertebrates was quantified within 40 radial transects, covering an area of 10,922 m2 on 19 reefs. Lobster were identified on 12 or the 19 reefs at very low densities (maximum of 0.01 lobster/m2). Conch were observed on 9 reefs at a very low density, with slightly higher abundances in six locations (>0.1 animal/m2). Diadema were rare or absent in all locations except on a leeward patch reef near southwest Cay (PB-01) and a shallow reef community near Banner Reef. Table 5.
