Lobsters are recognizable faunal elements that play an important role as top predator in the trophic webs in benthic ecosystems and have an economic importance due to the intensive and valuable fishery. In Rocas Atoll (03°51′S 33°48′W) the presence of five species of lobsters in low tide pools was observed by visual census. These were: Enoplometopus antillensis Lütken, 1865; Palinurellus gundlachi Von Martens, 1878; Panulirus argus (Latreille, 1804); Panulirus echinatus Smith, 1869; and Parribacus antarcticus (Lund, 1793). This atoll appears to be dominated by P. echinatus followed by P. argus, P. antarcticus, P. gundlachi and E. antillensis, respectively. We also observed the presence of some potential predators that perhaps feed on lobster species and control these populations in the atoll. This work and future information could help to better understand the variability of lobster diversity and density in this unique atoll.
