Octopuses are one of the most fascinating marine animals. There are around 300 species of octopuses in the world, many of whom can change their colour and texture.

A video capturing the stunning colour-changing ability of an octopus is going viral on social media. The video, shot by marine enthusiast Nick Ruberg, shows an octopus changing its colour into inky black as the camera approaches it. In the next few seconds, the octopus changes not only its colour but also its texture to match the ocean floor and camouflages itself.

A popular science-based account on Twitter named Wonder of Science (@wonderofscience), shared Nick Ruberg’s video Wednesday.The tweet soon went viral with over one lakh likes.

Commenting on the video, a Twitter user wrote, “anyone that argues that all nature’s beauty and wonder is simply an accident, they should look closer at these amazing creatures.”

According to Ocean Conservancy, a non-profit environmental advocacy group, many cephalopods like octopuses have specialised cells that are encased around a sac called the cytoplasmic sacculus. These sacs are filled with pigments like red, black, or yellow. When an octopus stretches the sac more pigment appears on the octopus’s body, while when they shrink the octopus goes back to its normal colour.
