In the present study, we report recent findings of the sea pens Anthoptilum grandiflorum, Pennatula inflata and Halipteris africana in order to update their distributional information in areas under Argentine jurisdiction. In this sense, we update the southern distributional limit of the species in Argentina to the Burdwood Bank. We also report the association of A. grandiflorum and H. africana with the sea anemone Hormathia pectinata. The kind of relation between both associates is discussed. This represents the first record of an association between sea pens and anemones for the South Atlantic Ocean and the second report in the world.
