Starfish Day for Julie

Julie, a Facebook Friend, tells me that she really digs starfish. Because I can use all the friends I can get and Julie never scolds me for attempting a humorous comment on her status changes, I think that her polite hint deserves an appropriate response.

Since I do, despite my geeky aura, appreciate the sentimentality evoked by images of starfish, I’ll set the stage with this mushy shot:

I can hear the murmurings of “Awwwwww . . .” from here. I have no idea who the people were. They simply happened to be standing on the rock while I composed the image. It was a very lucky break.

The truth is, I nearly overstayed my prime time. During an attempt to catch the sailboat out on Astrolabe Bay,  I was nearly inundated by a wave crashing on the rocks:Now that I’ve set the mood in my inimical way, we shall proceed to tickle Julie’s fancy with some yummy starfish.

You know, I’ve seen  this shape before.  There is a logo somewhere, on a product or representing some organization, that is a cartoonish figure of a starfish (two eyes, a mouth, etc.) with the top of the star a little crooked, as if it were wearing a hat which is a bit askew. This Fromia milleporella  reminds me of that:Please keep in mind that this is Annual General Meeting week and I’m sitting here trying to stay interested and not fall asleep. My mind wanders in particularly unusual ways. I keep feeling fluid draining from my sinus cavities. It’s seawater. My wife, Eunie, tells me when to raise my hand to vote on a motion. As you can imagine. I’m a little more distracted than usual.

But wait! Let’s get back to Julie’s starfish. This is one that you’ve seen here many times, the lovely Choriaster granulatus:You may be tiring of seeing this critter, but I’m nowhere near finished taking pictures of it.

Here’s is another which you have seen here many times:I’m sure that everyone out there has seen images of the Mimic Octopus which is able to contort and recolour its body in marvelous ways to appear to be any of several non-octopus critters. However, have you ever seen a Linckia laevigata  mimic a snake? As of now, you have.

It may surprise some that this lump is a starfish:Called a New Guinea Cushion Star (Culcita novaeguineae),  it appears more like a bumpy, spiky football. In fact, it is supremely tempting to pick it up and attempt to kick it back and forth between divers using the floppy fins.

Of course, we never actually do  that.

Bon appétit,  Juli.

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:

Cushion Star or Sea Pincushion (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:

Cushion Star or Sea Pincushion (Culcita novaeguineae)

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:

Nudibranch (Notodoris minor)Compare the distinction of detail between the shot above and the shot in this post. I think that I’m finally getting it figured out.

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

Nudibranch (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.
The sticky white filaments of Bohadschia argus on a flip-flop

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.
