Golden Oyster, Anomia trigonopsis 51-83 mm
“The golden oyster is an irregular, oval shell with different valves. The convex upper valve is wrinkled, shiny and deep gold to slivery white. The thin, translucent lower valve grows to fit the contours of the underlying rock or shell. The upper valve develops the same sculpture because during growth the two valve margins fit together. Some lower valves are bright green. The hardened byssal plug emerges through a large hole near the hinge to secure the golden oyster onto the rock of shell.”1
Nana Joy would walk the beach; Stanmore Bay, Mission Bay, then Snells Beach or Algies Bay looking for these shells. I would walk with her, each time I found one of the ‘right’ shells, I would feel a sense of satisfaction. Nana Joy was clear about what she wanted, while she loved many shells, these were The Best. Golden, thin and fragile looking.
