20 Fascinating Facts About Andaman And Nicobar Islands We Bet You Didn’t Know

Long fabled among travellers for its gorgeous beaches, underwater wonders and primeval location in the middle of nowhere, the Andaman and Nicobar Islands are still the ideal place to get away from it all. The archipelago has around 572 islands of which only 36 are open to tourists. The island population is an interesting mix of south Indian and Southeast Asian settlers, as well as Negrito ethnic groups on some islands whose arrival here still has anthropologists baffled.

Adding to the intrigue is the fascinating ecosystem that exists on the island – the spectacular coral reefs, the biggest crabs, the largest turtles, the most vibrant fish and the most beautiful butterflies.

While most of us know about Andaman and Nicobar’s legendary beauty and charm, these emerald isles are intriguing in more than one way. Ptolemy and Marco Polo documented the isles as home to fierce man-hunters and Jean-Jacques Cousteau dedicated a movie to them called Invisible Islands.

Here are 20 incredibly interesting facts about these islands.

1. The names ‘Andaman’ and ‘Nicobar’ are taken from the Malay Language

The name Andaman is presumed to be derived from Hanuman, who was known to the Malays as Handuman. The name Nicobar seems to be a corruption of the South Indian term ‘Nakkavaram’ (Land of the Naked) as indicated in the great Tanjore inscription of AD 1050.

2. The most widely spoken language on the islands is not Andamanese or Nicobarese

North Sentinel Island is home to one of the most isolated human populations in the world. The Sentinelese, thought to number around 300, have rebuffed all contact with the modern world and fire their arrows at anyone who comes within range.  They are thought to have directly descended from the first human populations to emerge from Africa, and have probably lived in the Andaman Islands for up to 60,000 years.

Pandanus is a densely arranged, wedge-shaped fruit that has an immensely hard, woody and fibrous body in which several narrow, edible seeds are embedded. Each section has a fleshy base that contains an aromatic pulp that, after cooking, is a staple food in Nicobar.
