BASSE-TERRE, Guadeloupe, Feb. 5 (UPI) -- A snorkeler taking underwater video in the Caribbean said he was shocked when an octopus dropped its camouflage and emerged from a reef.
"This guy took me completely by surprise while snorkeling in the Caribbean," Jonathan Gordon wrote in the video's description on YouTube. "I dove down to have a look at the shell that you can see just under where the octopus appears and as I approached the octopus came out of hiding. I had literally no idea he was there until I was about a meter away."
The video shows the octopus change colors from blending perfectly into the reef to a bright electric blue.
Some species of octopus are able to change their colors using specialized skin cells called chromatophores.
