Neuropeptides are a diverse class of intercellular signalling molecules that mediate
neuronal regulation of many physiological and behavioural processes. Recent advances in …

Species within nearly all extant animal lineages are capable of regenerating body parts.
However, it remains unclear whether the gene expression programme controlling …

Bioluminescence is the production of visible light by living organisms thanks to a chemical
reaction, implying the oxidation of a substrate called luciferin catalyzed by an enzyme, the …

Bioluminescence relies on the oxidation of a luciferin substrate catalysed by a luciferase
enzyme. Luciferins and luciferases are generic terms used to describe a large variety of …

The velvet belly lanternshark (Etmopterus spinax) is a small deep-sea shark commonly
found in the Eastern Atlantic and the Mediterranean Sea. This bioluminescent species is …

Opsins—G-protein coupled receptors involved in photoreception—have been extensively
studied in the animal kingdom. The present work provides new insights into opsin-based …

The cookie-cutter shark Isistius brasiliensis (Squaliformes: Dalatiidae) is a deep-sea species
that emits a blue luminescence ventrally, except at the level of a black band located beneath …

Regeneration as an adult developmental process is in many aspects similar to embryonic
development. Although many studies point out similarities and differences, no large-scale …

Symbiotic relationships are omnipresent and particularly diverse in the marine world. In the
Western Indian Ocean, the sea urchin Echinometra mathaei associates with two obligate …

Scientists have observed light sensitivity in a wide range of echinoderms over several
centuries, despite the vast majority of the phylum lacking eyes. Opsin-expressing cells are …
