The Bajau children in Borneo spend time on boats from an early age , and begin their hunting around the age of eight . French photographer , Réhahn , 35 , said the friendly children loved him taking their pictures and seemed happy to see a foreigner . Réhahn uses a Canon 5d Mark III to capture his stunning pictures , and spent eight days living among the tribe to learn about their lives . The Bajau live in small boats or stilted huts , relying on their extensive knowledge of the ocean to make a living through fishing . The young children learn from a young age how to swim or dive , and start their hunting as young as eight years old . Despite many of them not knowing their ages , or written communication , Réhahn described the peace and serenity that emanated from the water tribe . 'The children are like fish in the sea . Young children are sometimes on the boat alone , but all seemed very happy to see a foreigner , ' the 35-year-old French photographer said . 'Children were jumping from a wooden bridge and they wanted me to take their photo . They were perfect models . ' The Bajau tribe 's beliefs centre around a combination of animism and Islam , with their relationship with the ocean and its inhabitants being at the heart of the nomads ' existence . Happy and content ! Réhahn said the sea gipsies were like fish in the water , and spent a lot of their time jumping happily into the water from a bridge . Due to extended periods under the surface , the sea nomads have an enhanced underwater-vision , perfect for spearfishing . Réhahn said : 'When I arrived , children jumped on the boat to come near me . Some families invited me to their house ' Being around water from a young age results in the best divers being able to stay submerged at depths of 20 metres for several minutes , while they hunt for fish . The hunter-gathers mainly use spearfishing to get their produce , but can dive for pearls and sea cucumbers . Studies have shown that youngsters have exceptionally good underwater-vision due to being constantly in the ocean environment . As diving is such a big part of their lives , often their ear drums rapture at an early age . Regardless of their age , everyone in the Bajau tribe has a place and helps in some way to catch the fish . Splashing around ! Bajau children enjoy their water existence and play in the turquoise waves . The best divers are able to stay underwater at depths of 20 metres for several minutes , while they hunt for fish . Réhahn , who has over 180,000 fans of his work on his fan page , said : 'They are very welcoming and friendly . When I arrived , children jumped on the boat to come near me . Some families invited me to their house . ' Although some of the seafaring tribe are born on the ocean and never live on the land , more frequently the sea gypsies are heading to the shore for trade and to gather materials to build boats . Réhahn said the Bajau roughly know about age but time does n't matter much to them , and they live in the present , and live only for and by the water . Some female sea gipsies give birth on their huts with stilts , although many come to land to trade and get supplies , there are a small number who have lived entirely on the ocean throughout their whole lives . The tribe 's beliefs centre around a combination of animism and Islam , with their relationship with the ocean and its inhabitants being at the heart of their existence .
