Animals like chameleons and octopuses are renowned for their almost supernatural ability to change color and blend into their surroundings. Now, it turns out the blue shark (Prionace glauca) has some color-shifting powers of its own. Researchers at the University of Hong Kong have revealed just how the sharks obtain their striking blue hue and their capacity for changing color.
“Blue is one of the rarest colours in the animal kingdom, and animals have developed a variety of unique strategies through evolution to produce it, making these processes especially fascinating,” Viktoriia Kamska, a post-doctoral researcher in the lab of Professor Mason Dean at City University of Hong Kong, in a press release. Kamska presented the team’s research at the Society for Experimental Biology Annual Conference in Antwerp 2025, earlier this month.
