Two-faced hermit?

Rex was watching me again. I got down and stared right back at him, eyeball to eyeball. But what's that? Four eyes?

Rex and Joey?

It almost looks as though he has a second, smiling face under the eyestalks. A vertebrate sort of face, not crab-like at all.

I don't know what the second pair of "eyes" really is. Doing inventory; he's got the eyestalks, the long antennae off to the sides, the antennules between the eyestalks, two sets of maxillipeds for eating ... isn't he supposed to have three? So the "smile" must be the third, and smallest set of maxillipeds. But what are those "eyes"?

I took the same photo twice; this one in natural light, through the window, the next one with the flash. Look at the difference it makes!

The flash gives a sharper photo, and brings up the detail better, but it eliminates the translucence of the eyestalks and antennae, and the glow of the backlight. I think I like the first one more.

What do you think?
