Craspedochiton producta (Carpenter in Pilsbry, 1892) ACANTHOCHITONIDAE -10m, Dived, East London, South Africa, 41.0mm, F+++ Craspedochiton producta is an amazing chiton with extremely well developed girdles that partially cover the shell plates. It is endemic to South Africa, and live attached to hard substrates in rather shallow water ranging from about -5~30m. Very interestingly, members of genus Craspedochiton are known to use their wide, fleshy girdle to catch small prey; and are carnivorous unlike most chitons which are herbivorous grazers. Similar behaviour is known from genera Placiphorella (Mopalidae) and Loricella (Schizochitonidae), and are considered to be result of convergent evolution. An uncommon species, it is extremely variable in colouration and can even be bright pink or orange. Typical length including the girdle around 35mm (without girdle 20mm), very large specimens may approach 50mm (without girdle 30mm).
