Nine species of decapod larvae, including lobster (Homarus americanus), from the plankton were identified in a nearshore study area in northeastern Newfoundland. Charac-teristics including illustrations for field identification of larvae of these species are given. Occurrences of Stages I–IV Zoea and Megalopa of the more abundant species indicate possibly more than one spawning or hatching during summer. Evidence of oogenesis being equal to embryogenesis is presented for the species Eualus pusiolus and Crangon septemspinosa in this area. The occurrence of larvae of Caridion gordoni gives a most north-erly record for this species in the western North Atlantic.
