Resumen:
In this contribution we highlighted the importance of the gastropod Adelomelon ancilla (living and empty shells) as settlement substrate for the sea anemones Antholoba achates and Isotealia antarctica in soft bottoms of the SW Atlantic Ocean. Fifty percent of the sampled shells of A. ancilla presented at least one epibiotic anemone and up to a maximum of 6 anemones were reported in one living individual. Adelomelon ancilla shells are the first settlement substrate reported for I. antarctica. We also recorded the use of empty shells by Pagurus comptus and Propagurus gaudichaudii, as far as the less frequent record of other invertebrates and gastropod egg cases attached to the empty shells. These results are compared with the epibiotic organisms recorded on Odontocymbiola magellanica, another volutid species that shares the same habitat.
