Intertidal rocky strips are important habitats for conserving biodiversity in coastal regions, but scientific studies are scarce, particularly on the coast of El Salvador. The present study determined the distribution, abundance of polychaetes and other benthic macrofauna of the rocky intertidal zone of Mizata, during february, april and june (2017); establishing three horizontal and perpendicular transects to the coastline with 0.5 m height in vertical gradient, between four and five quadrants (25 cm2) were included during low tide, collecting intertidal fauna from the rocky substrate. The most abundant species were: Boccardia proboscidea, Neanthes galetae, Pseudonereis variegata, Typosyllis aciculata and Typosyllis variegata. These nereids and both species of Typosyllis inhabit the middle fringe of the intertidal zone dominated by Brachidontes adamsianus. Polychaetes were also associated with Chama coralloides and empty barnacle heads in the lower intertidal strip. Species richness increased in lower areas.
