Por la gran importancia que tiene la macrofauna se ha querido contribuir dando a conocer por primera vez, las especies de poliquetos y moluscos que existen en el área de Monteverde en la Provincia del Guayas.Five stations of the sandy substrates of the intertidal zone belong to Monteverde were analyzed and were identified represented by relatively few poliquetos like Nephtys singularis and Neanthes succinea. Among the mollusks the gasterópoda Olivella simistriata is the species that predominates in limits of the low tide a sandy substrate relatively clean. In the subtidal zone 15 stations were analyzed, as result 19 species of mollusks were identified being the class bivalvia or Pelecypoda the most abundant with their species acrita Nuculana acrita and Nucula paytensis. Of the gasterópoda the most abundant and frequents genus was Cylinchna sp. and, of the Escafópoda the genus Fustiaria sp. Among the benthónic polichaetos, the species Lumbrineris bassis is most representative of the area and the sandy slime is normally in substrate. Figures of relative abundance appear, is present at percentage, frequency, diversity and richness in the area of Monteverde.
