It was analyzed the spatial distribution of the benthic macrofauna of the Bay of Sechura (5°12’- 5°50’S and 81°12’ - 80°51’W) right after the end the 1997-98 El Niño. Temperature, dissolved oxygen, sand content (%), exhibited a decreasing trend from shallow to deep stations, while organic matter content, equitability and diversity increased with depth.
