A shell of the Cancellate Cantharus, Solenosteira cancellaria, was observed at University Beach. It is a relatively common species at this location.

Most shells found on the beach are occupied by hermit crabs.

Read more about this species at Encyclopedia of Texas Seashells, p. 215.

(Sorry about the grainy pictures; it was late and I increased the camera's sensitivity, which degrades photo quality).
