由於鳥嘌呤晶體受到壓力，在更深的海洋中游泳會使鯊魚呈現出更深的藍色。
Blue sharks have a unique color that is one of the rarest in the animal kingdom.
Scientists at the City University of Hong Kong discovered that the color of the skin comes from tiny nanostructures.
These nanostructures act as blue reflectors and help produce the shark's characteristic color.
The sharks' skin can also change color, which is a new finding in the animal kingdom.
The secret lies in tooth-like scales on the skin that contain guanine crystals and melanosomes.
These components are packed into separate cells like bags filled with mirrors and black absorbers.
Combining these materials creates a powerful ability to produce and change color.
Fine scale alterations due to factors like humidity or water pressure can affect the shark's body color.
Swimming deeper in the ocean can make the sharks appear a deeper blue color due to the pressure on guanine crystals.
