Can one handle Triops?
Triops are pretty hardy little creatures. They have a tough exoskeleton, and thus are reasonably protected from harm. However, it is unwise to attempt to pick up a small Triops because they are still susceptible to being crushed when they are juveniles. After they reach about ¾ – 1 inch in total length, they can be handled, but do handle them gently. They should not be left out of the water for more than a minute or so, or they will die. Also, Triops are quite fragile directly after molting, so it would be harmful to them to attempt to pick them up directly after they molt.
