The paper analyzes mineral phases in marine species shells and skeletons using XRD, finding calcite, aragonite, or their mixtures, with MgCO3 content varying taxonomically and environmentally.

This study identifies that Argonaut octopuses use a distinct set of proteins to form their shell-like eggcase, which is not homologous to the shells of other mollusks.

The paper identifies shell matrix proteins and conserved domains in Nautilus pompilius and compares them with other conchiferans to study shell evolution.

The paper provides empirical evidence for monogamy in the firefly squid, Watasenia scintillans, showing that most females store spermatangia from a single male and all embryos are sired by that male.
