This review presents a synthesis of shark bioluminescence knowledge. Up to date,
bioluminescent sharks are found only in Squaliformes, and specifically in Etmopteridae …

Learning how complex traits like eyes originate is fundamental for understanding evolution.
In this review, we first sketch historical perspectives on trait origins and argue that new …

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

Almost all animals can sense light, but only those with spatial vision can" see."
Conventionally, this was restricted to animals possessing discrete visual organs (eyes), but …

Background Two visual systems are present in most arthropod groups: median and lateral
eyes. Most of our current knowledge about the developmental and molecular mechanisms …

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 …

R-type lectins are a widespread group of sugar-binding proteins found in nearly all domains
of life, characterized by the presence of a carbohydrate-binding domain that adopts a β …
