Beachgoers have captured amazing footage of an octopus ‘blushing’ as it emerges from its hiding place on a Welsh beach.<\/p>\n
The curled octopus transforms from a ghostly white to deep orangey-red as it crawls out from under a rock at Menai Bridge beach, Anglesey.<\/p>\n
Experts think the animal may have changed colour when it detected nearby people and perceived them as a potential danger.<\/p>\n
After crawling up the rocks with its long tentacles, the octopus made it safely back into the sea.<\/p>\n
Octopuses have thousands of cells under their skin that each contain sacs filled with different-coloured pigments.<\/p>\n
