Each day under the hard-packed sands of northeast Florida beaches a deadly game of cat and mouse takes place between the efficient predator Neverita duplicata (Say, 1822) [Shark Eye] and its favorite prey Donax variabilis Say, 1822 [Variable Coquina]. Because this hunt can take place as much as six inches below the surface, it's difficult to make first-hand observations. However, by reading tell-tale "tracks in the sand" one can easily deduce  the particulars. Presented below are some images of the hunter, the hunted, and what a collector is likely to observe on a northeast Florida beach.
