ARCTIC Macrobenthos Communities of Cambridge, McBeth and
ABSTRACT. Thirtyeight marine invertebrates, including molluscs, echinoderms, polychaetes and several minor taxa, have b en added to the previously described benthic macrofauna inhabiting Cambridge, McBeth and Itirbilung fiords in northeastern Baffin Island, Northwest Territories, Canada. The fiords...
