Phylogeny, divergence times and species delimitation of Tonicia (Polyplacophora: Chitonidae) from the eastern Pacific Ocean [PDF]

open access: yesZoological Journal of the Linnean Society, 2019
AbstractThe chiton genus Tonicia is composed of 12 species, 11 of which are found in the eastern Pacific, but the taxonomic status and geographical distribution of these species have long been controversial. In this study, we compare eastern Pacific Tonicia species using molecular systematics. The molecular markers cytochrome oxidase c subunit I (COI),

Hull flotation function in the eggs of Mopalia ciliata (Chitonida: Mopaliidae) and swimming of its larvae through ontogeny [PDF]

open access: yes, 2014
The free-spawning species of chitons produce eggs that are enclosed in a capsule known as the hull. Particularly in the group of Chitonida, this outer coat is formed by spine projections.

A molecular palaeobiological perspective on aculiferan evolution

open access: yes, 2014
Recent advances in fossil, developmental and molecular studies show that aplacophorans are derived molluscs that evolved from chiton-like ancestors presumably in the Ordovician period (488–440 Ma), thereby forming the clade Aculifera along with extant ...

Towards a phylogeny of chitons (Mollusca, Polyplacophora) based on combined analysis of five molecular loci. Organisms Diversity

open access: yes, 2020
This study represents the first phylogenetic analysis of the molluscan class Polyplacophora using DNA sequence data. We employed DNA from a nuclear protein-coding gene (histone H3), two nuclear ribosomal genes (18S rRNA and the D3 expansion fragment of ...
