A 1" long pod would be very long. I have not seen mine on the suface of the water but thats not saying they will go up there from time to time. They really look more like little crustations. With a curved back and antenea.
will find the sponge in your overflow and the pad and sponge in your wet/dry as a great home. Infact if you pull your sponge out and just hold it for a few minutes you might find some of these pods
comming out of the sponge trying to figure out whats up.
A pod crawling around on your hand really feels strange.
