Itis pretty amazing how far down you can go indert the surface of the ocean. When you go down far, you have to be able to hold your breath super long. It is pretty remrkable to see that a Sperm Whale can dive 2,950 feet under water! A Weddel Seal can hold there breath under water for 98 minutes, are you kidding me! That is more than an hour and a half. We as human can dive 120 feet andcan hold our breath for 20minutes, with the help with our dry suitand Scuba gear of course.
