Just returned from a week of leisurely paddling, eating, lounging, and exploration of the mangrove islands off Sanibel Island, Florida Gulf Coast, near Ft. Myers. Nice and warm; returned to slush and snow. Trip as guests of friends who live winters on a 30 ft houseboat, the mothership for access to the Ding Darling USFWS Refuge there. Unbelievably productive area, with biomass per hectare manyfold times what we see up here: fish, birds, algae, plants. Oh, yeah, and hurricanes, too! Photos here: http://www.pbase.com/bartenderdave/sanibel08 Captions to come later. This one is a spiral of egg casings from a whelk, running maybe an inch acros and 15-20 inches long, on the sandy beach.
