The research team, led by experts at the City University of Hong Kong, delved into the shark's anatomy and identified a distinctive feature in its skin. When shark observers take out their boats to sea, they often see the same shark appearing lighter in the morning and darker on the same afternoon. Upon photographing these breaching sharks and comparing their shades with color boards, observers attributed these changes in the shark's skin color to hormones.
The nanostructures responsible for producing blue sharks' lovely hue may also allow them to change colour depending on their environment. The shark scientifically known as Stegostoma fasciatum is well known for their dramatic change of color pattern as it ages. Scientists just discovered a new color morph! Blue sharks' unique nanostructured skin enables dynamic color changes via guanine crystals, with potential implications for bio.

While the color-changing technique was something the researchers initially discovered by happenstance, National Geographic reports that South Africa's Wilderness Shark Research Unit utilized a wide variety of tools and methods to arrive at this new hypothesis once they realized what was happening under the surface. Shark biologist Ryan Johnson attests to taking hundreds of snapshots of the.
