Planktic foraminifera provide excellent material to investigate the influence of development on morphological disparity, as they grow by the sequential accretion of chambers on to their test. Typically, Benthic Foraminifera are bottom dwellers and thus reside at the seafloor. ISBN 978-1-4899-5760-3, World Foraminifera database (Online database).

This World Database of all species of Foraminifera ever described (recent and fossil), is part of the World Register of Marine Species (WoRMS), a global initiative to provide a register of all marine organisms. Planktic foraminifera have become increasingly important biostratigraphic tools, especially as petroleum exploration has extended to offshore environments of increasing depths. The tests of recently dead planktic foraminifera are so abundant that they form a thick blanket over one third of the surface of the Earth (as Globigerina ooze on the ocean floor).

Planktic forams grow their own shells using calcium carbonate, the material used to make the same shells you can find on the beach. Over 10 million scientific documents at your fingertips. Some examples of key indicator genera include Melonis, Chilostomella, ... Planktic foraminifera are not found in the Bonarelli level, while the presence of radiolarians indicates relatively high productivity and an availability of nutrients. During their life cycle they construct shells consisting of one or more chambers, and these shells remain as fossils in marine sediments. For studies of relatively recent deposits simple comparison to the known depth distribution of modern extant species is used.
