N2 - Fifteen species belonging to four families of large, benthic, symbiont-bearing foraminifera were collected alive in coral reef-associated environments on Palau, Western Caroline Islands, and Oahu, Hawaii. Typical habitat was algal veneer over rubble or other hard substrate. R-mode cluster analysis revealed four species clusters around Palau. One cluster, dominated by Calcarinidae, was characteristic of seaward reef flats. The second cluster, made up of Marginopora vertebralis , Amphistegina lobifera and Peneroplis planatus , was characteristic of more protected shoals having water depths of less than 5 m. The third cluster, typified by A. lessonii , characterized reef slopes at 5-20 m. The fourth cluster consisted of more deeply dwelling species, especially A. radiata and Operculina ammonoides . In the samples from Oahu, the calcarinid cluster was absent; M. vertebralis was associated with P. pertusus ; A. lessonii was associated with A. lobifera and P. planatus ; and A. bicirculata and O. ammonoides typified deeper samples. The depth and habitat zonation exhibited by these species indicate their usefulness as paleoenvironmental indicators and as sediment tracers.
