Weddell Seal's are on 4 different episodes, and are #3 on Daredevils, #8 on Tough Babies, #2 on Divers, and #7 on Dieters. Prior to the Weddell Seal giving birth, the mom goes three weeks without eating anything. Babies experience the most significant temperature change on the planet. The difference between being in the womb, and being on the ice is an extraordinary 60 degrees. Babies need to drink seal milk from their mother immediately. They will double in size in only a week. They also need to learn how to swim, and hold their breath almost immediately. Adults can hold their breath for an hour and 20 minutes, and can descend as deep as 600 meters, where the water pressure is so intense, it collapses their lungs. However, they don't need lungs, since they carry twice the amount of oxygen in their blood as humans.
