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