Testudiatom replaced its ancestor testudohexapodia acta in all the beaches of Wright. It now can absorb the silica and makes a skeletal structure out of it. This structure helps hold the photosythetic membrane in them. Each organism resembles a small flat plate that are microscopic. They do best in moist sand. They can produce spores from the center of the plate which will fall off and grow into another testudiatom once exposed to moist sand.
