Epibiota associated with Patella aspera shells in the Azores

This dataset contains records of epibiotic assemblages associated with the shells of the limpet Patella aspera collected from two locations on each of the nine islands of the Azores archipelago between July and September 2011. The dataset provides information on epibiont diversity, occurrence, abundance, and host size, supporting studies of marine biodiversity, epibiosis, and spatial variation in species assemblages across oceanic islands.
