Shells

I started a Cornish shell collection with my children recently. So yesterday we went to our local beach on Flushing to look for new additions. Lying down I took a really close look and was rewarded with a whole bunch of tiny species. On this photo, 14 species comfortably fit on a square inch. Species names in a clockwise spiral:

Mangelia nebula

Tritia incrassata (Thick-lipped Dog Whelk)

Trivia arctica (Arctic Cowrie)

Tricolia pullus (Pheasant Shell)

Bittium reticulatum (Needle Whelk)

Littorina obtusata (Flat Periwinkle)

Calliostoma zizyphinum (Painted Top Shell)

Steromphola cineraria (Grey Top Shell)

Littorina saxatilis (Rough Periwinkle)

Tectura virginea (White Tortoise Shell Limpet)

Rissoa lilacina

Peringia ulvae (Mudsnail)

Nucella lapillus (Dog Whelk)

Steromphola umbilicalis (Flat Top Shell)
