TABLE 5 in Twelve new Demospongiae (Porifera) from Chilean fjords, with remarks upon sponge-derived biogeographic compartments in the SE Pacific

TABLE 5. Comparative micrometric data on spicule length x width and known distribution for Oceanapia guaiteca sp. nov., O. spinisphaera sp. nov., and the species of Oceanapia occurring in Chile-Peru and additional biogeographic provinces deemed closely related 1. Micrometric values for spicules are expressed in µm.
