Why do elephant SEALs dive so deep?
Elephant seals have a very large volume of blood, allowing them to hold a large amount of oxygen for use when diving. In addition, they have a larger proportion of oxygen-carrying red blood cells. These adaptations allow elephant seals to dive to such depths and remain underwater for up to two hours.
Do Navy Seals have to drown?
