This was under a rock in about 3 feet of water off the southeast coast of Cuba. I can't find a good match for it in the books. Could it be Stenoplax bahamensis?

Dear Les,
As often chitons are not always easy to ID on a picture only. The illustrated specimen belongs to Stenoplax and 3 species are known from Caribbean waters. The following key can help in differentiating the species: 1a Tail valve as long as wide, mucro postmedian . . . . . . . . . . . . . . . 2 b Tail valve wider than long, mucro central . . . . . . . . . . . . . . . . . . 3 2a Concentrical riblets on end valves and lateral areas with the grooves between them smooth or nearly so . . . . . . . . . . . . . . . . S. floridana b Concentrical riblets with the grooves between them transversely latticed . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . S. bahamensis 3 End valves with smooth, somewhat wavy concentric ridges; Atlantic species . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . S. purpurascens Based on this key and on other features like coloration I think the species is Stenoplax purpurescens (CB Adams, 1845) Thanks for sharing this nice picture, Bruno. |
