Some aspects of the biology of Calliopius laeviusculus (Krøyer) (Crustacea, Amphipoda) in the northwestern Atlantic
Calliopius laeviusculus is an amphiboreal species found on rocky shores in the western Atlantic from Hudson Bay south to Long Island Sound. Fifty percent of the females were calculated to be mature at 5.6 and 6.7 mm in the summer and winter respectively in Newfoundland waters, but, in Labrador, matu...
