Genus/specie: Megastraea undosa

GENERAL CHARACTERISTICS: The Wavy Turbin Snail has a heavy, sculptured shell with undulating ridges in a turbinate-conical shape with a thick, pearly lining.
The light brown or tan shell color is caused by the fibrous periostracum covered with coralline algae and other epiphytes.

Size: up to 6 inches

DISTRIBUTION/HABITAT: Found from Point Conception and the coastal Channel Islands to northern Baja California, Mexico. They range from the intertidal zone down to depths of over 250 feet.

DIET IN THE WILD: M. undosa are herbivores feeding on various types of algae.

REPRODUCTION; Year around with peaks in spring and fall.

CONSERVATION: Because wavy turban snails are hand-picked by divers, the fishery is at low risk for bycatch .
Wavy turban snails are abundantly available and have a high productivity rate, so over- harvesting is less likely.

REMARKS: The shells of wavy turban snails are used to make buttons!

The meat has an abalone-like texture and taste; foot of the snail is processed and sold to restaurants as an abalone-like product, “wav alone”.  They can be prepared many ways: grilled, sautéed, battered and fried, in pastas, in chowders and soups, and in stir fries.
