This sighting is from over a month ago, when the King Tides were taking place. Cindy Morey had a wonderful find during the extra low tides. She wrote, “This Sea Star with 22 arms was alive and in a tide pool way out in the rocks during low tide on Irish Beach. It was really something to see. I've only seen one other one near the same place many years ago.” What Cindy photographed was a beautiful Sunflower Sea Star, Pycnopodia helianthoides.

About ten years ago, a disease called the Sea Star wasting disease severely impacted many Stars, but it seems to have hit the Sunflower Stars the hardest. It’s estimated 90 percent of the big Stars died. I have not had a sighting of one since the outbreak so Cindy’s photo was so very welcome. I shared Cindy’s photo with folks at NOAA and they were excited too. Sunflower Stars prey on Purple Urchins which proliferated in the Stars absence, so with the Stars hoped for recovery, balance may be restored in the ocean.

Thanks to Cindy for allowing me to share her photo with you here. Cindy is an artist with the Coast Highway Artists Collective. You can take a look at this link: https://coast-highway-artists.com/

Rain has returned to the Mendonoma Coast. Hooray!

The largest Sea Star in the world is the Sunflower Seastar, Pycnopodia helianthoides. Travis Winters was visiting relatives on the Mendonoma Coast and took his camera along when he hiked the Stornetta Public Lands. There he found this Sea Star.

I count twenty-one limbs on this big Sea Star. They can have between 16 and 24 limbs and they grow over three feet across. They eat Sea Urchins, Clams, Snails and other invertebrates.

Thanks to Travis for sharing his photo with us here.

Will Ericson was exploring the tide pools at the Stornetta Public Lands at low tide. He ducked into a cave and discovered this Sunflower Seastar, Pycnopodia helianthoides.

This Sea Star is the largest sea star in the world, growing to more than three feet across. Will said this one was more than a foot across. They eat clams and snails but prefer sea urchins. A lovely "meadow" of sea urchins was nearby. They usually have between 16 and 24 limbs. It *looks* like this one has 21.

I thank Will for allowing me to share his unusual sighting with you here.
