Photo Journal May and June 2010

May and June are whelk time. Triangles indicating that they are surfacing can be seen every few feet on the beach. Scores of people who had never seen a live mollusk are delighting in seeing the whelks and other mollusks such as clams, moon snails, Lettered Olives, Coquina and augers that are surfacing. This also is when visitors arrive in droves, ensuring pleasant encounters with both children and adults on nearly every walk and plenty of help when I need it. An alarming fact this year is that no Channeled Whelks have been seen.

Another feature of May and June are migrating stingrays. The ones I see each year are Cownose Rays, Rhinoptera bonasus. One person mentioned seeing red rays. Several persons told me that a small "stingray" was stranded in a tide pool. I suspect that it was a Smooth Butterfly Ray, Gymnura micrura. I was unable to find it.

stingray barb
stingray spiracle
This species has a single barb a third of the way down its tail. Although venomous, rays seldom strike unless threatened. Because they are bottom feeders, injuries to feet and legs often occur when people step on them. Rays flap their fins, disturbing the sand to expose small invertebrates to eat such as sea stars and sea urchins.
Behind each eye stingrays have a spiracle to breathe in oxygen. This is important because they rest on the bottom of the ocean, often beneath sand. Water is expelled through gills on the lower side of the ray.

Sea Grit, composed of minute shells and shards of shells, contains many newborn and unusual fragile shells.
   
Nothing in my yard has been trimmed this year, including the frost-bitten leaves of this Sago Palm, Cycas revoluta. It's a jungle out there. While inspecting my yard this morning with a landscaper, we noted this pollination cone on -- of course -- a male Sago Palm. Sago Palms are not true palms. Above is a close-up photo of the pollin on the 20-inch-tall and 5-inch-wide cone.
