摘　　要：We report for the first time the presence of local populations of the starfish Odontaster penicillatus in the regions of Atacama and Antofagasta,Chile.This finding indicates an extension of the distribution limit of 500 km with respect to the last observation made in 2007 in Isla Grande de Atacama.A total of 121 specimens of O.penicillatus were recorded at depths of between 8 m and 24 m.They were associated with rocky substrate and with different species of barnacles,sponges and bryozoans.The presence of O.penicillatus expands the knowledge of the benthic biodiversity of the region,and the development of studies on its ecological importance will be promoted.
