Found the following specimen and I would like to know the id. Taken with Plan Apo 10x/0.45, polarized light, stacked.

Wow Rogelio, this is another gorgeous photo!

Sorry, but as to an ID I can't contribute more than the obvious, i. e. Crustacea: Phyllopoda: Cladocera, here in a not so often seen ventral view, presumably easier to achieve with your inverted scope.

Betty,

Thank you.

It was moving always; but with some pauses that allow me to take quickly a set of pictures to do the stack. The side view set of pictures were not good and I was not able to take a dorsal view set.

It's a water flea, Ceriodaphnia.

And I forgot to say it is a beauty! :)

Perhaps Ceriodaphnia reticulata?

Rogelio, congratulations for your selection as monthly Administrator's Appreciation Award. A fine picture, indeed!

One thing, I've softened the title on the topic to reflect that the ID is tentative. As I understand it that name is properly attached to a critter whose type locality is a marsh in Norway. I know that C. reticulata is a widespread species by some accounts, but applying it to a specimen from the American tropics seems like a bit of a stretch.

Structure of the postabdominal claw is listed as one distinguishing characteristic of reticulata [REF], so if you have a good lateral photo that might help shed some light on the ID.

Rik,

Thank you!

I deleted all side view pictures I had. :(

If I find it agin I will try to get side view of it. I had not found it again.
