The Florida Worm Snail

The Florida Worm Snail (Vermicularia knorrii), is named after its similarity with worm tubes. This Snail starts making a regularly coiled shell until it is roughly 0.5 inch long. From then on, the shell becomes uncoiled, acquiring its typical, irregular shape. The irregular shells of Worm Snails help anchor them inside sponge colonies. A close relative also found on Sanibel and Captiva is Fargo Worm Snail (Vermicularia fargoi).
