Foraminifera caught my interest. They are precious and their study covers so many areas: From field- to home-work, from rock-formations to photography. SEM and computer -stuff. I like the worldwide foraminiferal community - so help- and thoughtful people. Share may enthusiasm.
Last year I received in a plain envelope some plummercells filled with hundreds of foraminifera from young scientist Wafaa in Sanaa, Yemen. I started with SEM images (59 so far), see www.foraminifera.eu/wafaa.html.
I think optical images are a nice addition to illustrate this diverse fauna near Socotra, Yemen in the Indian Ocean and Peneroplis planatus a nice start.
The image is taken with a simple ocular camera. Sharpness is achieved by stacking different single images
Peneroplis is very common in the East Meditteranean, Red and Arabian Sea, Indian Ocean .... You may easily get it from sand-samples.
