Between 1985 and 1990, population processes were inferred from size-frequency distributions of 21 species
of bathyal echinoids collected by submersible in Bahamian waters. All species studied reproduce by means
of long-lived planktonic larvae. Local populations mostly consisted of larger individuals; cohorts of recent
recruits were observed only rarely. Growth of individuals in a cohort was evident between sequential samples
of several populations, but Palaeobrissus hilgardi sampled at San Salvador over a three-year period had a stable
size distribution with no apparent growth, recruitment or size-specific mortality. On a regional basis, bathy·
metric range width was correlated significantly with a measure of recruitment frequency, suggesting that
species with less stringent habitat requirements recruit more successfully on the bathyal slope.
