Fuzzy Chiton (Acanthopleura sp.)

This species of chiton grows to be about 7 cm (2.8 in) in length. The girdle is densely spiky and usually has a few black bands.

Consumes: Hair Algae, Cyanobacteria, Diatoms and Turf Algae

The surface of the valves (or plates) in this species is almost always heavily eroded in adults, but when not eroded, the valve surface is granulated. The valves are thick and heavy. The morphology of the West Indian Fuzzy Chiton contains a fifth valve, split into two symmetrical half valves that are independent to each other and other valves. A griddle-like tissue splits the valves.

This species is common within its range in the tropical Western Atlantic, but it is often not noticed, because its color and texture are similar to the rocks on which it lives.
