Unknown arthropod
Copyright © 2015 Susan Leach Snyder

Unknown arthropod
Naples, Collier County, Florida, USA
November 24, 2015
Size: .9 mm
The first image is a dorsal view with the anterior end at the top. The second image is the ventral view with the anterior at the top. The third image is a lateral view. This creature fell into a pitfall trap placed among reindeer moss lichens (Cladina confusa). It is unlike anything I have seen before and I am wondering if it might be a tardigrade.

Poduromorpha
Good thinking, Ken. It could be Neanuridae given the pointed buccal cone. But also Odontellidae is a candidate given the presence of a furca (that is what it looks like anyway...).
But the specimen is too distorted to do a decent ID.
To relax the tissues of the specimen, put it in a solution of 10% lactic acid. This will not only relax the tissues but also make the specimen more transparant. Follow the process under the microscope. If you leave it in the solution too long the specimen will desintegrate...
If you do not have access to lactic acid simply use sour milk.

Thank
you for confirming Ken's hypothesis that it is a Poduromorpha. I'll try some sour milk to see if I can relax it. If that works, I'll send more photographs your way.

Moved for expert attention
Moved from ID Request.

These are just going to get buried in ID Request. Frans will let us know if Collembola is correct, or if we need to move them elsewhere.

Thanks
for your recognizing this as a collembolan and sending it on to Frans!

I seem to be seeing six legs, and a pair of antennae...
I'm wondering if it might be a Collembolan--maybe something in Neanuroidea?

Tardigrades would have eight legs and no antennae, I believe.
