Removing the Uncertainty of Chitin Structure in Chitons (Mollusca: Polyplacophora: Chitonida)

Zoologischer Anzeiger
Chitons, also known as "living fossils", have been proposed as one of the earliest differentiated groups of molluscs. Although Polyplacophora is an ancient group of molluscs, very few studies have been conducted on the chitin of these organisms compared tobivalves, gastropods and cephalopods.

Tonicia atrata and Chiton cumingsii (Polyplacophora: Chitonidae): First records in European waters

Zootaxa, 2013
At present, over 300 species of marine alien Mollusc are reported from the European waters (Streftaris et al. 2005; Zenetos et al. 2010). However, only three alien polyplacophoran have been recorded: Chaetopleura angulata (Spengler, 1797), Acanthopleura gemmata (Blainville, 1825) and Chiton hululensis (E. A.

Mitochondrial Genetic Divergence of Chiton articulatus (Polyplacophora: Chitonida) in the Mexican Tropical Pacific

Marine and Freshwater Research
Context Chiton articulatus is a gonochoric, free-spawning mollusc with short-lived trochophore larvae inhabiting rocky shores along the fragmented and heterogeneous Mexican Tropical Pacific (MTP). Its limited dispersal in this patchy environment may lead to genetic divergence among populations.
