Actually this is not a seal, but a sea lion... You can notice the ear flaps behind the eyes. I swam with this playful creature in Port Lincoln, aka Shark Capital of South Australia. It was totally worth the risk! NB. Try to look upside down :-)
Thank you Michele; it is one of my dreams to dive in Italy. Many years ago I visited Milan for business. I hope one day I will be lucky enough to go back for leisure and stay longer :-)
