I've never seen the ocean or been even close to getting to go there so my oean encounters would be at the aquariums that I love soo much! This puffer fish was my favorite by far, it followed me each time I visited its tank - pressing its lips up against the glass - I found out later how smart these guys are! I went on a behind the scenes tour where I found out how they file this guys teeth down periodically because their teeth dont stop growing just like rabbits and rodents - very cool!
