24 Jun 22 Prior to the decimation of the sea star (starfish) population in 2013-14 due to sea star wasting disease, our local intertidal zone waters were teeming with invertebrate life. Following that disastrous die off, the waters have been far less populated with the type of marine life so abundant prior. "The disease was thought to be a virus, but currently, there is evidence that points to bacterial infection resulting from an imbalance in the sea star’s microbiome (microorganisms in a particular environment). A proliferation of bacteria on the surface of sea stars leads to reduced oxygen, which essentially causes the star to suffocate. While this “suffocation” is not transmissible star to star, the bacteria are. Decaying stars exacerbate the situation by providing even more organic material for the bacterial communities to flourish. Impacts vary by species and site conditions, and there is still a lot to learn as more information becomes available." Each year since we have returned to the areas we used to enjoy combing to find a very slow but consistent return of what had been lost. Prior to the die off we used to see something in the neighborhood of a dozen different species of sea star, now we just see one or two. Likewise, we used to see sea anemones in shades of red, pink, cream, blue, green, white, and yellow. One I don't ever recall seeing around here is a green one. Last week as we were slip sliding over the rocks during that -4 tide we were both surprised and delighted to see many green ones. That was a first but unfortunately the greens were the only ones we saw. Nevertheless, that was a treat and I took several different shots of them. For this Friday's macro /closeup I'm sharing a shot of a single specimen. Wanting to make sure I could cut through the glare off the surface of the water, I made sure to take along a polarizing filter. When I went to put it on the lens I realized I had brought the wrong one, so my attempts to get a strong glare free image were somewhat hampered. Fortunately this shot turned out reasonably well. Would have liked to have removed the trash on the inside of the specimen but I wasn't about to stick my hand inside that critter and take a chance on getting seriously stung. I supposed I could have removed it in editing but then it wouldn't have been fully accurate.
Other than a little bit of contrast enhancement to better show off the design of the critter, this is what the camera captured. Green Anemone Nikon D500; 18 - 200; Aperture Priority; ISO 1,000; 1/125 sec @ f / 9.
