A unique free-living geniculate coralline algal bed formation

Extensive surveys along the Arraial do Cabo Bay (23° S 42° W; Fig. 1a), SE Brazil, have shown the presence of the first record of five unique free-living GCA beds (Fig. 1b) comparable to rhodolith beds (Foster 2001). The morphology is spheroidal (Fig. 1e), comparable to the rhodolith growth form of...

Description
Summary:Extensive surveys along the Arraial do Cabo Bay (23° S 42° W; Fig. 1a), SE Brazil, have shown the presence of the first record of five unique free-living GCA beds (Fig. 1b) comparable to rhodolith beds (Foster 2001). The morphology is spheroidal (Fig. 1e), comparable to the rhodolith growth form of non-geniculate coralline algae (NGCA) from shallow-water, high-hydrodynamic beds (Steller et al. 2003).
