Received on October 3, 1993; accepted on December 22, 1995 Sampling near Bermuda by trawling and SCUBA diving yielded 16 species of salps in August 1989 and March-April 1990. Several species occurred in the surface waters only at particular times of the day. suggesting diel vertical migrations on different schedules. At the time of sampling, salps were present in low numerical abundances and constituted only a small fraction of the total zooplankton biomass.
