Reophax (ree-owe-fax), one of the foraminifera in which the series of chambers forms a linear structure rather than forming a spiral structure - which is more usual. This is the vacated test. Phase contrast.

Reophax species have a relatively simple, linear chamber arrangement. This specimen was harvested in Nueces Bay, South Texas. Image courtesy of Pamela Stephens, Midwestern State University.
