[Note Guidelines] Photographer's Note
Two Ochre Seastars on a California Mussel-covered rock at sunset provided an interesting opportunity. In post-processing, I straightened the horizon as much as possible without losing too much of the foreground and adjusted for contrast by about two points.

The Ochre Seastars are usually orange or purple, though occasional near-black ones can be found along our beaches.

Description of Species:

The Pisaster ochraceus, generally known as the purple ochre star or ochre star, is a common sea star found among the waters of the Pacific Ocean and is distinctively different to the sea stars found in the waters of the Atlantic, according to Ricketts (1985). Although they are called the purple ochre star, they can be found in a variety of shades from purple to orange and brown depending on its location and water temperatures. In more protected waters, they are more purple in color whereas on exposed coasts, their colors tend to be more orange or brown. This is especially notable in juvenile sea stars, whereas with adults it's not as much of a factor. The purple ochre star has five rays that range in length from 10 to 25cm long. When submerged beneath the water, the arms of this sea star are flexible allowing them to move about freely, however when exposed during low tides, the tissue is usually very stiff.

The stiffening of the tissue allows it to anchor itself to rocks or under rock crevasses during periods of exposure to air, a mechanism that is most likely used to protect itself from predators (Lambert, 2000).

Hello Feather,
This sea star looks very big may be the size of 25cm long as you mention in the note? A beautiful seascape. You should level the horizon line a bit. TFS.

Hello Feather,
How big this star is? It seems so huge... This is a strange picture because of its exposure but I think that you did quite a good job in PP; but, that you should have played with levels a bit though ;) Thanks,
