Their unique abilities could initially be mistaken for mutant traits. However, the real explanation lies in the intricate paths of evolution.
This fish, known as the pig wrasse, revealed a dual talent: the “chameleonish” ability to change color and a peculiar vision through its own skin.

How do fish manage to change color?
The ability to switch from color it is controlled by specialized cells in the skin of the fish called chromatophores. Detailed analysis revealed a remarkable adaptation system.
This fish's color changes are driven by a complex interaction between cells known as chromatophores, which are full of pigments.
The range of tones that the white wrasse can assume is the result of the different combinations of red, yellow and black pigments that these cells can form.
As the combinations happen and interact, the fish's surface cells transform into darker shades, creating a striking camouflage effect.
The biggest surprise came when the researchers investigated the mechanisms underlying this unique ability. They revealed that the amount of light plays a crucial role in the release of opsin, a light-sensitive protein.
This discovery connects with the presence of opsin-producing cells located directly under the chromatophores.
These recently discovered cells have shown a particular affinity for the shorter, bluer wavelengths of light that can penetrate through chromatophores.
The result is a veritable biological symphony: changing light levels lead to the release of opsin, which in turn influences the activity of chromatophores.
While researchers have uncovered what appears to be the central link between these phenomena, the intricate way in which opsin molecules regulate chromatophores still remains partially enveloped in mystery.
The revelation of this groundbreaking phenomenon in biology reveals yet another layer of the wonders that evolution is capable of producing.
The triggerfish, with its camouflaged ability and peculiar vision, reminds us that nature is a infinitely creative inventor, sculpting adaptations that challenge our understanding and expand our vision regarding the life.
