Ancient proteomes from tiny shell ornaments were successfully characterised for the first time, showing the unexpected use of mother-of-pearl from local riverine molluscs in both coastal and inland prehistoric sites.

A transmissible cancer that arose in a marine mussel spread from a single animal to become a global pathogen affecting two other mussel species in both Europe and South America.

Discovery of a novel neuropeptide signalling system in a deuterostome invertebrate reveals the evolutionary origin of prolactin-releasing peptide and its relationship with neuropeptides in protostome invertebrates.

No discernible latitudinal diversity gradient in rocky intertidal α-diversity as local-scale physical and biological processes outweigh global-scale environmental gradients.

Starfish feed by everting their stomach out of their mouth over prey and, interestingly, this unusual feeding mechanism is inhibited by substances similar to hormones that regulate feeding in humans.

Neither the presence nor the intensity of Hematodinium sp. parasitisation drives co-infection occurrence, severity, or diversity in the ecologically ubiquitous shore crab, Carcinus maenas.

A cellular map of a deep-sea mussel gill unveils how distinct cell types collaborate to cultivate intracellular symbiotic bacteria, providing insights into host–symbiont interactions and environmental adaptation in bivalves.
