These chitons come in a pack of 5 and are small reaching roughly about 1 cm in size. Similar to a grain of rice. They are herbivores feeding on algae and detritus with their radula (made up of 100 rows of teeth) used to scrape algae off of rocks. They go through 1 row of teeth a day! 
This species is captive bred here at K&P originated from Florida but can be found in other areas of the Caribbean and Texas and have been studied as early as 1845. 
They are broadcast spawners spending their juvenile life floating in the water column and settling to the bottom once reaching adulthood. 
Their bodies are made up of 8 plates surrounded by a girdle. These dorsal plates are sensory organs.
