Se registraron 17 especies,_x000D_ nueve de Gastrópodos y ocho de Polyplacophoros, de los cuales 12 fueron nuevos_x000D_ registros para el litoral de Huanchaco, siendo cinco de la clase Gastropoda: Fissurella_x000D_ pulchra, Fissurella sp., Crepipatella dilatata, Stramonita biserialis y Crassilabrum_x000D_ crassilabrum, y siete de la clase Polyplacophora: Acanthopleura echinata, Chiton_x000D_ granosus, Tonicia chilensis, Chiton sp., Chaetopleura sp.l, Chaetopleura sp.2 y_x000D_ Chaetopleura sp.3. Las especies con mayor densidad (indlm2_x000D_ ) fueron Prisogaster niger, Tegula atra y Chiton cumingsii con más de 30 ind/m2_x000D_ • Se determinó que el mayor número de especies pertenecieron a la clase Gastropoda, asimismo se observó que en marzo se registró el mayor número de especies (12).
