Parapriacanthus Explained

Parapriacanthus is a genus of sweepers native to the Indian Ocean and the western Pacific Ocean. Parapriacanthus are bioluminescent, with ventral light organs for counter-illumination. Parapriacanthus luciferase is a kleptoprotein, obtained from their diet on bioluminescent ostracods.^[1]
