Lovely shot Ken, this really shows the diversity of just 1 species/genus

Yep there are a lot of different species of Arcella, these here are the most common ones that I find around here. Thanks Kite!

Hi Ken, I might be wrong but I think I once read that Arcellas start out with clear tests and as they get older they absorb some sort of mineral which makes them darker in color. Have you heard that?

Yep I sure have Tom. They say the darker the test the older the Arcella

oooh, thats interesting to know, thanks Tom.

In that case I found an archaeic one the other day

it was very dark brown indeed, and I didnt get my normally wonderful colour show with a darkfeild condenser either.

Awww Ken... for a second there I thought you had overcome your fear of downloaded software

But hey... if you can train those little guys to do all the stacking work themselves... all the better!

Thanks Charlie, may instead of a flea circus, we can one day have an Arcella circus
