Using all three eyes

The camera sees more - and less - than my eyes do. Flipping rocks along the shore, left-handed, with the camera in the right hand, finger on the shutter button, I disturb crabs, who scuttle quickly under the next-door stone. Flip another; crabs. Another; more crabs. One stops to threaten me, pincers raised. "Come on, see if you dare!" I turn the camera in her direction, and she changes her mind and joins her friends under shelter.

Another stone. More racing crabs. Once they're gone, I see slow movement; flatworms. The camera sees them, unless the light is just exactly right, as brown smears. My eyes see the movement, the merest hint of it, going in a different direction than the slither next to it, the next flatworm.

Whelk egg cases, spiral tube-worms, and flatworms on the underside of a stone.

Wosnesenski's isopods, one lying upside-down for some reason, showing off his 14 legs. And a pair of crabs.

Sometimes, there's a nano-second of flurry, a miniscule splash; a baby sculpin, an inch long, gone to ground, now invisible. Maybe the camera will see him; I won't. But I saw the splash.

Some animals are only recognized, in these surroundings, by their movement. I learn to see them; the merest rise and fall of a limpet under the seaweed gluing herself down to the rock while the light threatens her; the split-second flip-flip-flip of a gunnel, the shrinking of an anemone, the characteristic sideways scuttle of a miniature hermit - snail shells don't move like that without a hermit resident; the writhing of a polychaete worm becoming one with the mud underneath, the squirting of a clam retreating deeper into the mud. The camera never sees those.

Spiral tubeworms, flatworms (the light was right- look for the eyes!) and a limpet, still on the move. I don't know what that tiny thing with the striped back"bone" on the stony patch in the centre is.

My eyes miss the very tiny critters. My reading glasses are in my pocket; they get in the way when I look through the viewfinder, and the light is too bright to see the screen. So I point and shoot, looking for the green square that says the auto-focus has found something interesting. Or find a safe, non-painful (broken barnacles are sharp!) place to kneel so that I can get my head down a few inches from the stones and look through the viewfinder.

White shells, a sea of white shells; must be barnacles. The camera knows better. Waving seaweeds; no, the camera discovers tentacles or antennae. Or a mass of worms.

The camera saw these. I didn't.

This photo includes two masses of ribbon worms; the upper one is a knot of Paranemertes peregrina (p. means wandering), the purple ribbon worm, with a very purple body and a creamy belly; the orange ribbon worm, Tubulanus polymorphus; and the green ribbon worm, Emplecotnema gracile, with its green top and yellow belly.

The lower knot appears to be all green ribbon worms.

And there are three flatworms and a trio of crabs.

Sometimes things are easier; I find an underwater species tossed up to die on the shore. These I can pick up and move to a better background.

Unidentified species of hydrocoral. Notice the yellow "bud" at the tip of the branches.

Habitat for the critters found above. The stripes parallel to the shore are probably old glacier tracks on sandstone.
