Tentacles!

Still testing shutter priority mode.

The anemones in my aquarium cause me no end of trouble, with their semi-transparent tentacles always in motion, and their habit of picking the most awkward spots to settle in.  I've taken hundreds of photos and deleted almost all of them. A fast shutter definitely helps.

Double lines in Val's tentacles. She often twists them in spirals like this.


A quick shot, with minimal processing; cropping, resizing, white balance is all.

The largest of the Orange Striped Green Anemones, Haliplanella lineata, (What a big name for such small critters!) has a good appetite, and a full crown of tentacles to keep it in groceries. It seems to have eaten something dark, which has left a black mark in the base, invisible in normal circumstances, but not when it's parked on glass.

These anemones have from 60 to 100 tentacles, up to about 2 inches long. This one is getting close to that maximum.

Feeding, this anemone has a pale greenish cream column. The upper half is the same translucent off-white as the tentacles. I was starting to doubt my identification, when in protest against the hot weather and my slowness in providing more ice, it shut down, condensing itself to a half-inch round dark green mass, with the orange stripes it's named for. Chilled and happy once more, the stripes disappeared.
