Cajetan's Chiton

Lepidopleurus cajetanus

Cajetan's chiton has an elongated body that is more than twice as long as it is wide. Its valves and narrow girdle exhibit colors ranging from dirty white to light ochre. The lateral areas of the chiton are highly elevated and feature concentric ridges, while the central areas are characterized by longitudinal chains of granules. This distinct morphology helps differentiate it from other chitons in its habitat. This species is typically found in the Eastern Atlantic and the Mediterranean, inhabiting environments along the European coast down to Israel. Cajetan's chiton prefers a benthic lifestyle, residing at depths ranging from intertidal zones to 200 meters, although most occurrences are shallower than 40 meters. Divers may encounter this chiton on rocky substrates or in areas with abundant algae. Cajetan's chiton feeds primarily on algae, grazing on the surface of rocks and other substrates. It reproduces through a gonochoric life cycle, where eggs hatch into planktonic trocophore larvae that later settle on the bottom as young adults. Encounters with this chiton during dives can be intriguing, as they often blend into their surroundings, making them somewhat cryptic. The conservation status of Cajetan's chiton has not been evaluated by the IUCN, indicating a lack of specific data regarding its population trends.
