Fish 'steals' glowing protein: Genome sequencing proves unique survival strategy

Phys · · 372 words · By Tohoku University

A study published in Scientific Reports reveals that the fish Parapriacanthus ransonneti achieves bioluminescence by obtaining luciferase proteins from its prey rather than producing them genetically. Whole-genome sequencing confirmed the absence of luciferase genes in the fish, demonstrating a unique biological adaptation called kleptoproteinism.
