Microscopic Crystals Enable Blue Sharks to Shift Colors

Rapid Summary

• Researchers at the City University of Hong kong have explored the interesting mechanism behind the blue shark’s (Prionace glauca) striking color and capacity for subtle color-shifting.
• Blue sharks stand out in their unique coloration: blue on top, silver on the sides, and white underneath. This is attributed to specialized dermal denticles containing guanine crystals (reflective) and melanosomes (light absorbing).
• using advanced microscopy techniques,researchers revealed that altering crystal arrangements can change the shark’s color from blue to silver,green,or gold. Variations in environmental factors like humidity or water pressure may influence these changes.
• The study employed digital simulations and 3D modeling to highlight how small shifts within cells containing up to 152 guanine crystals create different pigment effects by altering light refraction angles.
• scientists see potential applications of this research in nanotechnology and bioengineering fields due to its insights into structure-driven functions.
