The Dreaded Sticky Thong and Other Curiosities

Before we get to the thong (no,  not that  kind) I’ll show you a few other odd critters that live in my front yard.

This peculiar thing is commonly known as a Cushion Star, or as my Grandmother told me, a Sea Pincushion. If you’re on less familiar terms with the critter, you may call it Mr. Culcita novaeguineae:

I doubt that they are aware if you get the gender right, so it won’t much matter. They reproduce both sexually and asexually, so such distinctions probably seem silly to them.

I admit with some shame that it nearly impossible to resist the urge once in a great while to pick up one of these football sized legless starfish and give it a toss at your dive buddy. I’m certain that this activity is much opposed by “Amalgamated Cushion Stars Committee Against Humans Playing Football With Us”, a loose confederation of local Cushion Star bowling clubs. How they manage to bowl with no arms is beyond me. Anyway, here’s a side shot:

They are squishy in a very strange way. If you poke it, it feels hard at first, almost stone-like. However, if you nudge gently and continuously, your finger will begin to make a dent that continues to deepen until you begin to feel very guilty and pull your finger away. Then, slowly, the dent will become more and more shallow until it is gone.

You’ve seen Notodoris Minor  before. It is absolute torture to get an image of these things which shows their actual shape. They are so monochromatic that the camera, even your eyes, can’t capture the subtleties of shading that model the contours of the critter. Visually, they look like a vivid yellow blob. It strains the eyes to make out any details. I worked feverishly on these shots to bring out the fine differences of shade in these images to show you bizarre shape of these nudibranchs:

Hard to please today?  Okay, how about two Notodoris Minor ?

Take that!  However. I think that we may have intruded on a little tête-`a-tête,  so let’s leave them to it.

Finally, I can complete my report to you concerning the stickiest substance know to man, the filamentous cuvierian tubules exuded from the stinky end of the Leopard Sea Cucumber, a kind of bech-de-mere (Bohadschia argus).  I wrote about this before.

What I didn’t know, on the day a friend accidentally stepped on one (no harm done to the Leopard), that my friend Amanda Watson took a photo of the goo-encrusted flip-flop (or thong, as we call them here).

I managed to get most of it off without covering my fingers. Imagine the stickiest, nasty old chewing gum that has been baking on the sidewalk for a week.

This stuff is worse. Much worse.
