The name “foraminifera” is derived from the Latin word foramen, which means ‘opening’, referring to the apertures in their shells, or tests. Fossilised tests are found in sediments as old as the earliest Cambrian (about 545 million years ago) and foraminifera can still be found in abundance today, living in marine and brackish waters.

Catalogue of the Fossil Foraminifera in: British Museum Natu

Either they float in the water column (planktonics) or live on the sea floor (benthics). First identified in the 5th Century, the Foraminifera species are single-celled protozoans commonly found in marine environments (some are much bigger in size). Despite being single-celled, microscopic organisms, Foraminifera species are characterized by the presence of shells known as tests. The video in this episode of Shelf Life explores the Museum’s fossil collection of tiny marine organisms known as foraminifera or—when even scientists admit six syllables is a mouthful—forams.
