Exhibiting signs of sea star wasting disease (loss of limbs, white lesions). 50-75 dead or dying individuals were observed at the site with the same clinical signs. Tissue samples were collected and deposited with park rangers for cold storage and molecular work. Possible first record of SSWD in florida and infecting L. senegalensis. Will update if molecular data confirms SSWD.

I was surprised to see ice crystals formed on the Bull Kelp which had washed ashore. It's been so cold, and the kelp was in the shade on the beach. Nothing else had crystals, so I wonder if they were formed from some chemical emitted from the kelp? Once I saw "Silky Hair Ice," which looks like white cotton candy, formed when carbon dioxide made by fungi pushes filaments of ice from logs under certain cold conditions. Here are 5 photos.
