Nannotax

Description: Catinaster with rays which bifurcate to form a distal rim, but which do not extend significantly beyond this rim. The rim continues to the proximal pole producing a basket-like body. N.B. short pseudo-rays are often formed where the tips of bifurcations meet.

Remarks:

Range: NN8-10, this is the first Catinaster species to appear and is the most common.
