Several weeks ago I received a sand sample from Istria, Croatia. Unfortunately I don’t have any more details about the location but the sample got my attention nowadays due to a small label that said: “Foraminifera”. So just from curiosity I made several photos and, indeed, there are plenty of small foraminifera inside! The photos below are just 4 mm wide so you can imagine the real size of the individual particles (click on the thumbnail to see the bigger image – real size: 8 mm width).
