Pearl Divers

At Sea World I saw pearl divers! They were in a 10 foot tank with oysters and they would sell the pearls that they found. Pearl divers can hold their breath a very long time one of them could hold his breath for five minuets! I wonder what kind of training that they have to endure in order to be able to do that! They can blow ring bubbles which I thought was pretty cool. Then me being the 12 year old girl that I am took selfies with them!
