Mollusk shell 2.1. Introduction 2.2. Diversity of mollusk classes 3. Structural, microstructural
and ultrastructural considerations on the shell 3.1. Structure of the shell and mineralogy 3.2 …

Molluscs comprise the second largest phylum of animals (after arthropods), occurring in
virtually all habitats. Some are commercially important, a few are pests and some carry …

Mollusca represents the second largest animal phylum but remains poorly explored from a
genomic perspective. While the recent increase in genomic resources holds great promise …

Studies of micromolluscs are essential in the malacology of the 21st century. Our
understanding of molluscs has been chiefly based on large-sized species, and there are …

The origin of molluscs among lophotrochozoan metazoans is unresolved and interclass
relationships are contradictory between morphology-based, multi-locus, and recent …

Despite the figure of complete bivalve mitochondrial genomes keeps growing, an
assessment of the general features of these genomes in a phylogenetic framework is still …

Background Widespread sampling of vertebrates, which comprise the majority of published
animal mitochondrial genomes, has led to the view that mitochondrial gene rearrangements …

Sea slugs (Gastropoda: Opisthobranchia) are characterized by extensive morphological
homoplasy. In particular, reduced or absent shells are predominant throughout the group …

Background Bivalve mitochondrial genomes exhibit a wide array of uncommon features, like
extensive gene rearrangements, large sizes, and unusual ways of inheritance. Species …

We present the first analysis of cephalopod mitochondrial gene order and construct
phylogenies based on gene order using Bayesian, distance, and parsimony analysis …
