Abstract

A diverse and rich foraminifer fauna has been observed in core and grab samples obtained from Ayvalık (North Aegean coast of Turkey) and Antalya (Southwestern Turkey). Morphologically abnormal individuals of Peneroplis pertusus (Forskål) and P. planatus (Fichtel & Moll) showing Coscinospira characteristics were commonly observed in these sediment samples. Previous findings from Çeşme (East Aegean Sea) indicate that such anomalies in peneroplids are unrare events. The aim of this study is to determine the possible causes of this abnormal test development. Gametes and juveniles of different species of peneroplids may fuse to form such aberrant morphologies. On the other hand, the clusters of Amphicoryna spp. with two or three individuals observed in the Pacific and in the Mediterranean partially support the idea of colony formation.
