Excavating sponges boring into the precious red coral from the Cape Verde Archipelago

Four species of sponges boring into Corallium rubrum were identified in colonies collected in Cape Verde (Atlantic Ocean). Two species are probably new, and in particular Alectona sp. 1 is strongly related to A. triradiata described for the Indo-Pacific area and also excavating into Corallium sclera...

Summary:Four species of sponges boring into Corallium rubrum were identified in colonies collected in Cape Verde (Atlantic Ocean). Two species are probably new, and in particular Alectona sp. 1 is strongly related to A. triradiata described for the Indo-Pacific area and also excavating into Corallium scleraxis. The disjunt distribution of the new species of Alectona respect to the congeneric and highly similar species A. triradiata excavating the same substratum (Corallium spp.) strongly suggests a Tethyan relict distribution of this excavating genus strongly connected to the disjunt and relict distribution of the genus Corallium. The evidence of circular and radial signs of erosion on pits surface produce by Thoosa armata similar to the ones described for Alectona spp. together with other similar and shared characters support the inclusion of the genera Thoosa and Alectona in the family Thoosidae.
