We have telephones that allow us to talk face to face and now Robot Navel sharks swimming in our oceans. This current futuristic world we live in just got a little to real for me. 

The Navy has been testing a new water based robot that not only looks but also swims exactly like a shark. The robot is called Ghost Swimmer and will be used to spy and observe ships undetected. The shark is about 5 foot long and can swim at depths of up to 300 feet.

Bottom line here is there are robot sharks in our oceans and I am now forever a pool guy.
