Biodiversity of Chilean sea anemones (Cnidaria: Anthozoa): distribution patterns and zoogeographic implications, including new records for the fjord region

The present paper provides a complete zoogeographical analysis of the sea anemones (Actiniaria and Corallimorpharia) of continental Chile. The species described in the primary literature are listed, including depth and distribution records. Records and the taxonomic status of many eastern South Paci...

Since 1994, we have collected more than 1200 specimens belonging to at least 41 species of Actiniaria and Corallimorpharia.
