Hari TulsidasHogfish, the chameleons of the ocean, can "see" with their skin even after they die, thanks to light-sensing cells beneath their colour-changing cells. These cells act like "internal Polaroid film" that captures the changes in their skin colour and helps them adjust it to match their environment. This remarkable ability could have implications for sensor technology and bio-inspired design. #hogfish #colourchange #biomimicry https://www.livescience.com/animals/fish/color-changing-hogfish-use-their-skin-to-see-themselves-even-after-theyre-dead?utm_source=flipboard&utm_content=HariTulsidas%2Fmagazine%2FMind+and+Matter
GripNews🌘 Hogfish“看”得到周圍的環境，即使它們已經死了-紐約時報
➤ Hogfish的色彩變化是如何實現的？
✤ https://www.nytimes.com/2023/08/22/science/hogfish-skin-camouflage-dead.html
研究人員發現，Hogfish的皮膚中有一種神祕的新型細胞，可以讓魚不僅監測其周圍環境，還可以編輯其皮膚顏色。這種魚類可以在不到一秒的時間內在三種顏色之間切換，而且即使死了也可以進行色彩變化。研究人員使用發光抗體來定位opsins，並使用透射電子顯微鏡來觀察細胞結構，發現opsins不在皮膚表面，而是在一層chromatophores下面，並集中在一種以前未知的細胞類型中。
+ 真是一個有趣的發現，我從未想過死亡的魚也可以進行色彩變化。
+ 這種新型細胞的發現對於我們對動物的瞭解有很大的貢獻，期待更多的發現。

"the #hogfish is known for its color-changing skin. The species can morph from white to mottled to reddish-brown in a matter of milliseconds to blend in with #corals, sand or rocks... Can hogfish detect light using only their skin, independently of their eyes and brain?"
This fish doesn't just see with its eyes, it also sees with its skin
A few years ago while on a fishing trip in the Florida Keys, biologist Lori Schweikert came face to face with an unusual quick-change act. She reeled in a pointy-snouted reef fish called a hogfish and threw it onboard. But later when she went to put it in a cooler she noticed something odd: its skin had taken on the same color and pattern as the deck of the boat.
