How Do Pearl Divers Adapt Their Bodies to the Ocean?

Answer

Before the 20th century, pearl divers had to adapt their bodies to the ocean because of the extremes they had to go to in order to retrieve the pearls. Divers had to dive to extreme depths (up to 100 feet) and possessed little equipment to aide them. They would grease their bodies to maintain heat, use a nose plug, place greased cotton balls in their ears, use rocks or other heavy immersible objects to help them reach depths faster, and carry something to put the oysters in. Still, divers were subject to dangers such as sharks, waves, drowning, or losing consciousness upon resurfacing (another risk for drowning).
