Step down shark, the octopus has just soared top of the ocean’s cool list.
An explorer got a shock when he dove down to inspect coral reef and this chap literally appeared out of no where.
The master of disguise completely blends in with its surroundings.
But when approached it turns into an luminous blue colour and rises from the reef.
The incredible video was uploaded to YouTube. The description reads: ‘This guy took me completely by surprise while snorkeling in the Caribbean.
‘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 metre away.’
