Probably a Harpacticoid copepod, hard for me to say for sure from the one image (not that I'm an expert.) Tisbe biminiensis is an example, but I don't know if its this one.

Apocyclops imo, you can see the one eye and 2 antennae

Another pic could help determine if it’s this or harpacticoida

I'm sticking with a Harpacticoid, though it's not looking like Tisbe to me. As I understand Cyclopoids (Apocyclops) are pelagic, not benthic, so since it was crawling on your glass I don't think it's likely one of those. Of the common benthic copepods sold, the Tisbe biminensis and Tigriopus californicus, neither is a dead on match, though this one seems to carry its eggs more like a trigriopus (one mass centered under the tail) vs. the Tisbe (two sacs on the sides of the tail.) Harpacticoids have smaller antennae than pelagic copepods because they don't need such a strong ability to swim, and while this is a freshwater study, it looks vaguely similar to the Attheyella illinoisensis that's described here (and fits the harpacticoid feature description it mentions) https://dam.assets.ohio.gov/image/upload/ohiodnr.gov/documents/coastal/owc/OWCAtlas_Copepods.pdf

Agree, if it was crawling it’s harpacticoid
