Thais clavigera, copyright R. Tanaka.

Belongs within: Rapaninae.

Thais, dog winkles, is a genus of predatory gastropods found on rocky shores and mangroves. Members of the genus have a very low-spired, basally unconstricted shell with a very broad aperture and an outer lip extended to form a curving channel at the adapical end of the aperture.
