The Developmental Stages of Paracalanus Crassirostris Dahl, 1894 (Copepoda, Calanoida)1)

The Developmental Stages of Paracalanus Crassirostris Dahl, 1894 (Copepoda, Calanoida)1) THE DEVELOPMENTAL STAGES OF PARACALANUS CRASSIROSTRIS DAHL, 1894 (COPEPODA, CALANOIDA)1) BY THOMAS J. LAWSON and GEORGE D. GRICE Woods Hole Oceanographic Institution, Woods Hole, Massachusetts 02543, U.S.A. INTRODUCTION Species of the genus Paracalanus are common in estuarine and neritic zooplankton, but there has been no complete study of the developmental stages of any species that are based on laboratory cultures. Paracalanus crassirostris Dahl, 1894, the smallest described species in the genus, occurs from Brazil (Bjornberg, 1963) northwards to Cape Cod (Deevey, 1948) along the Atlantic Coast of the U.S. Elsewhere it has been reported from the Cape of Good Hope (Tanaka, 1960), the Gulf of Guinea (Marques, 1949), the Suez Canal (Gurney, 1927) and the coastal waters of India (Sewell, 1912; Wellershaus, 1969). The species is eurythermal and euryhaline as it has been reported in waters which ranged from 1 to 30° C and from 3.4 to Because of their small size (adult females measure in length from 0.4 to 0.6 mm) individuals of P. crassirostris readily pass through the apertures of plankton nets that are routinely used for collecting zooplankton.
