Raphidiophrys (rah-fid-ee-off-riss) is a centrohelid heliozoon. Like other centrohelids, it has thin untapering arms, which have prominent extrusomes. The arms are supported by microtubular axonemes which terminate on a central granule (centroplast) which can just about be seen here. Distinguished from other genera because the cell is enclosed in a layer of loosely adhering boat-shaped scales with thickened margins. Differential interference contrast. This picture was taken by David Patterson of material from Limulus-ridden sediments at Plum Island (Massachusetts USA) in spring and summer, 2001. Image copyright: D. J.

Description of Raphidiophrys: Centroheliozoa with flat tangential siliceous scales consisting of two parallel plates connected by internal radial septae (seen in scanning electron-micrographs as radial striations or ribs). The scale has a hollow marginal rim. Radial elements are absent. May form clusters of cells. Type species: R. viridis Archer, 1867.
