Encyclopedian Dictionary ( Aquaculture ): Alonella

Alonella - Zooplankton

The Genus Alonella is a group of very small waterfleas. Fine features of the carapace and postabdomen are used to distinguish among species - necessitating use of a high-powered light microscope at a minimum.

I am not certain yet which species this waterflea would be classified among, but I'm positive it's Zooplankton and fairly certain it falls within the genus Alonella.
This photo was created by fine-focusing at two separate depths and merging the photos. Nice seeing its wee little ~~legs~~ (antennae?) in detail.
