Aesthete Pattern Diversity in Chiton Clades (Mollusca: Polyplacophora): Balancing Sensory Structures and Strength in Valve Architecture

Journal of Morphology, Volume 285, Issue 11, November 2024.
Synchrotron X‐ray μCT reveals the internal structures of chiton shells. Dense sensory channels of the aesthete network evolved from simpler vertical configurations found in Lepidopleurida to more complex, coalescing networks in Chitonida. ABSTRACT Chitons possess the most elaborate system of shell pores found in any hard‐shelled invertebrate.
