Actinocyclus octonarius

[Rene]

Hi guys, came across this beauty today in a fresh marine sample:





It's pretty common in the North Sea waters, but at 80um dia it is a big one. The valve pattern is thick and pretty pronounced, with the typical actinocyclus 'eye' at around 5 o'clock. I've cropped it here out of a full frame  at 25x25um:

Hallo Rene,

Zeer mooie foto's. Ik geloof dat ik me ook maar eens in zeewater ga verdiepen. Gr,
