3d model of a Large Foraminifera (NHMW-GEO-1996z0123/0002)

<p>3D scan of a large foraminifera (<em>Cycloclypeus carpenteri</em>) from the backstage collection of the Geology and Paleontology Department of the NHM Vienna. This specimen was picked from Onna Town, Okinawa, Japan W-Coast in a depth of 70 meters.&nbsp;<em>Cycloclypeus carpenteri</em>&nbsp;is a foraminifer, i.e. a single-celled protist with a chambered shell made of calcium carbonate. Foraminifera grow their entire life by forming new chambers and attaching them to existing chambers in a specific arrangement.</p><p>Foraminifera grow their entire life by forming new chambers and
attaching them to existing chambers. With a diameter of up to 13 cm, <em>Cycloclypeus carpenteri</em> is one of the largest recent (today living) large foraminifera.
This specimen measures 5.5x4 cm.&nbsp;<em>Cycloclypeus carpenteri</em> lives in 40–100 meters water depth in
warm, calm, nutrient-poor areas of the Indo-Pacific. Due to the
symbiosis with diatoms, the specimens can grow for several years and
thus reach their special sizes. The very flat shape enables the
symbionts to receive enough light for photosynthesis even at depths
below 40 meters.&nbsp;<em>Cycloclypeus carpenteri</em> belongs to the family Nummulitidae.</p>
