Two new species of Poecilosclerida (Porifera: Demospongiae) from Terra Nova Bay (Antarctic Sea)
Antarctic sponges have been studied since the 19th Century and are relatively well known compared to other world faunas (Calcinai & Pansini, 2000). Moreover, due to the peculiar characteristics of the Antarctic environment, their spatial distribution is certainly more homogeneous than for faunas...

Antarctic sponges have been studied since the 19th Century and are relatively well known compared to other world faunas (Calcinai & Pansini, 2000). Moreover, due to the peculiar characteristics of the Antarctic environment, their spatial distribution is certainly more homogeneous than for faunas at lower latitudes (Sara` et al., 1992). A total of 33 Demosponge species, already known for the Ross Sea, were identified and reported in this article, with an additional two species described here as new. Two new species of Poecilosclerida Crella (Crella) aurantiaca sp. nov. (Crellidae) and Mycale (Aegogropila) denticulata sp. nov.
