Chain catshark or chain dogfish, Scyliorhinus retifer. Above photographed with daylight bellown showing fluorescent colours when photographed under special blue or ultraviolet light and filter. Scyliorhinus retifer. Is one of four elasmobranch species shown to possess biofluorescent properties. They exhibit bright green fluorescence patterns resulting from the presence of fluorescent compounds in their skin. Catsharks possess the ability to detect the green biofluorescence that is emitted by their conspecifics and this fluorescence creates greater contrast with the surrounding habitat in deeper blue-shifted waters (under solar or lunar illumination).

C'est l'une des quatre espèces d'élasmobranches qui possèdent des propriétés biofluorescentes. Ils présentent des motifs de fluorescence vert vif résultant de la présence de composés fluorescents dans leur peau. Les Catsharks possèdent la capacité de détecter la biofluorescence verte émise par leurs congénères et cette fluorescence crée un contraste plus important avec l'habitat environnant dans des eaux plus profondes à décalage bleu (sous un éclairage solaire ou lunaire).
