Foram Taxonomy - Modern planktonic foraminifera About 40 species of planktonic Foraminifera live in the world's oceans today. They live at all latitudes, from the tropics to the poles, residing primarily in the euphotic zone. The photographs below were assembled in the early 1960's by Allan Bé, a distinguished micropaleontologist who worked at Lamont-Doherty Geological Observatory. For over 40 years they have been passed around and used by many labs and taxonomists and were published as a complete set in 1977. With the encouragement of Allan's colleagues Stan Harrison and Patty Catanzaro and the permission of Elsevier*, I am posting them here so they will continue to be of use to bug-pickers around the world. Species identification key can be found below. Click thumbnails for full-size images:
