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 Roussettes 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).
