Shot this good few years ago using a Canon 110 S point and shoot with underwater setting turned on,great little camera , carried it everywhere with me... this a an Octopus called 'Jerry" I befriended on my diving in Pafos Cyprus ...found a kids car in the water and gave it to him to add to his collection of rocks that octopus use during the day to create a type of fence around their den. and got him to grab like this and just took the shot ...at around 5mtrs depth ...
