~ The Bay of Bengal, the largest bay in the world, forms the north-eastern part of the Indian Ocean.
~ Roughly triangular in shape, it is bordered mostly by India and Sri Lanka to the west, Bangladesh to the north, and Burma (Myanmar) and the Andaman and Nicobar Islands to the east.
~ A number of large rivers – the Ganges and its distributaries such as Padma and Hooghly, the Brahmaputra and its distributaries such as Jamuna, Meghna, Irrawaddy River, Godavari, Mahanadi, Krishna and Kaveri – flow into the Bay of Bengal.
~ The International Hydrographic Organization defines the limits of the Bay of Bengal as follows: The Bay of Bengal appears as Sinus Gangeticus or Gangeticus Sinus, meaning “Gulf of the Ganges”, in ancient maps.
~ Many major rivers of the Indian subcontinent flow west to east before draining into Bay of Bengal.
~ Its main channel enters and flows through Bangladesh, where it is called Padma River, before joining Meghna River.
~ However, Brahmaputra River flows from east to west in Assam before turning south and entering Bangladesh where it is called Jamuna River.
~ The Irrawaddy River also spelt as Ayeyarwady of Burma flows into Andaman Sea of Bay of Bengal and once had thick mangrove forest of its own.
~ Some of the biggest ports in the world — Chittagong in Bangladesh and Chennai in India— are in the bay.
~ Other Indian ports on the bay include: Kakinada, Pondicherry, Paradip and Visakhapatnam.
~ An endangered species, the Olive Ridley sea turtle can survive because of the nesting grounds made available at the Gahirmatha Marine Wildlife Sanctuary, Gahirmatha Beach, Odisha, India.
~ A tropical storm with rotating winds blowing at speeds of 74 miles (119 kilometres) per hour is called a cyclone when they originate over the Bay of Bengal; and called a hurricane in the Atlantic.
~ Secondly because of the presence of outlying islands, namely Andaman islands and Nicobar islands and most importantly several major ports such as Kolkata, Chennai, Vizag, and Tuticorin along its coast with the Bay of Bengal.
