I saw this guy chilling and enjoying the sunlight, being a cold blooded guy he must be heating himself for some energy, like superman does from Sun, who knows probably he is a Super hero in his world.
Unlike usual caged habitats of a Zoo, this guy gets to roam around free, swim all day without getting bored of people staring at him all day, have you ever thought of from a caged animal's perspective, If you do you will realize it is pretty much sad. This guy must be making a plan for his prison break, poor thing doesn't know we greedy humans will never let that happen, anyways all power to you crock, hope your dreams would come true :)
