Researchers discover prism-like light-scattering crystals in deep-sea predator

Hiroshima University researchers found needle-like guanine crystals around the slender fangjaw’s light organs.

The crystals do more than reflect light: they bend and scatter it like tiny prisms.

The study, published in Biointerphases on May 26, highlights a new model for deep-sea bioluminescence control.

The fish’s crystal structure could guide biomimetic medical implants that better direct and recycle light inside the body.
