Eric - Next time you locate a concentration of these IR visible zooplankters, try and collect some and I will take a look at them to see what they are specifically. Prepare yourself a weighted jar/bottle with some sort of stopper w/ string attached. Lower the jar with a cord to the proper depth, pull stopper out with a string and when jar is full of water pull it to the surface. As bottle fills with water in the midst of a patch of zooplankton, adequate numbers of zooplankton will enter bottle with the water. Contact me and I will tell you how to preserve them for shipment.
