The Shompen, a critically endangered and largely isolated indigenous tribe of Great Nicobar Island, survive through intricate, sustainable hunter-gatherer practices. Their vital survival skills include expert knowledge of local flora and fauna, seasonal foraging, rotational foraging, and traditional crafting for hunting and shelter. 

Their core survival skills and adaptations to the dense rainforest environment include:

• Foraging & Ethnobotany: The Shompen possess deep knowledge of medicinal and edible plants. Their staple food is the pandanus fruit (known as larop). They use the White Dhup tree to make incense and mosquito repellent and use specific plant extracts as bee tranquillisers.

• Hunting & Gathering: Men hunt wild boar, birds, and small game using handmade bows, arrows, and wooden spears. Gathering is a crucial daily economic activity—handled largely by women—providing a steady, reliable food source of yams, roots, fruits, and insects. 
• Rotational Foraging: Rather than depleting an area, they live in small, semi-nomadic bands. They rotate across river-defined territories to allow the tropical forest ecosystem to recover, maintaining ecological balance. 
• Shelter Construction: They build temporary, raised leaf huts using forest timber, bamboo, and woven leaves to protect themselves from heavy tropical rains and wildlife.
• Water Management: They source fresh drinking water directly from the island's crisscrossing rainforest streams and utilise hollowed-out bamboo stems to carry and store water. 
• Craftsmanship & Fire-Making: They make tools and utensils using natural resources, including carving canoes for river navigation, weaving baskets, and making fire using traditional dry wood friction methods. They also create unwoven, felted clothing by beating the bark of specific trees with wooden hammers.
