Resumen

RETAMAL, Marco Antonio  y  ARANA, Patricio M.. Description and distribution of five decapod crustaceans collected in  deep-waters around Robinson Crusoe and Santa Clara islands  (Juan Fernandez archipelago, Chile). Investig. mar. [online]. 2000, vol.28, pp. 149-163. ISSN 0717-7178.  http://dx.doi.org/10.4067/S0717-71782000002800011.

Five decapod crustacean species caught in experimental and exploratory fishing surveys around Robinson Crusoe and Santa Clara islands, Chile (33º38'S, 78º49'W), are identified and described. The fishing operation consisted in setting pots, between 50 and 1000 m depth, from November 1996 to June 1997. The species found were Jasus frontalis (50-100 m), Projasus bahamondei (250 m), Paromola rathbuni (100-300 m), Chaceon chilensis (200-1000 m) and Ovalipes trimaculatus (100 m). The species distribution is discussed, as well as the colonization mechanisms and population renewal of these populations inhabiting islands and submarine mountains of the Southeast Pacific, which are remarkably distant them and from the South American continent
