I initially thought: “Wow!! Isn’t that an interesting hypothesis?”
My students might be forgiven for thinking pycnogonids are comprised only of legs and the hinges fastening those legs together.
As it turned out there was a very good reason that no clams with shells matching the description of Julia were ever collected. That singular reason is that Julia exquisita and all of its relatives having a similar shell are not clams, they are snails!
Not only are these tiny insects interesting as being marine insects, they have some of the oddest life history attributes that I have ever had the chance to encounter.
If you are like most people who have just set up a new aquarium, the pristine tank—even without the first fish—fills your soul with unadulterated joy. you are exercising Zen patience and letting things run for a few days, and you can hardly wait to bring it to life. Then you realize it’s already alive! You see that first spot of green or brown, or possibly an attractive golden glow, edging out from the “sterile” base rock. What the hell is that? You haven’t added anything to the tank. Life has arrived on its own—but where did it come from?
