Cancellaria reticulata
This gastropod’s shell has a cross-hatched texture and can be banded and cross hatched with tan to creamy white with blurry brown streaks. The inner lip of the aperture (opening) has two white folds on the columella (axis of the shell).
It is typically found in sand amongst turtle grasses from the low tide line to a depth of 50 feet. The snail has small teeth arranged on a radular ribbon which is most likely used to feed on soft bodied animals on the seafloor.
Live shells should never be taken from any Florida State Park.
