Biological and Oceanographic Conditions in Hudson Bay: 11. Echinoderms of Hudson Bay

For an arctic area Hudson bay appears to have an unusually meagre representation of echinoderms, both species and individuals being few in numbers. The echinoderm fauna includes 29 species, all high arctic forms none of which are peculiar to or especially characteristic of the region. The largest number of species is known from the southeastern portion; but here the greatest amount of collecting has been done. The relative richness of the several sections of the bay would appear to be, the west (richest), southeast, central, northwest, northeast and southwest (poorest).
