Abstract

Two sympatric crinoid species of the genus Oligometra are abundant on fringing reefs surrounding Lizard Island. Both species were present over all depths investigated. O. serripinna was most abundant in shallow water (6-19 m), and O. carpenteri in deeper water (22-25 m). Variation in behaviour between these two species includes differences in feeding periods and orientation of arms during daylight hours.
