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

Many marine species can regulate the intensity of bioluminescence from their ventral
photophores in order to counterilluminate, a camouflage technique whereby animals closely …

Background Squaliform sharks represent approximately 27% of extant shark diversity,
comprising more than 130 species with a predominantly deep-dwelling lifestyle. Many …

Bioluminescence has often been seen as a spectacular yet uncommon event at sea but
considering the vastness of the deep sea and the occurrence of luminous organisms in this …

Since recently, shark's bioluminescence has been recorded from two Squaliformes families,
the Etmopteridae and Dalatiidae. Pictures of luminescence, light organ morphologies and …

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 …

The velvet belly lanternshark, Etmopterus spinax, uses counterillumination to disappear in
the surrounding blue light of its marine environment. This shark displays hormonally …

Marine organisms are able to produce light using either their own luminous system, called
intrinsic bioluminescence, or symbiotic luminous bacteria, called extrinsic bioluminescence …

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 …
