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.
