There are only around 100 tigers left in Bangladesh's Sundarban forest, a number which is far lower than previously thought.
The mangrove forest, one of the tigers' biggest natural habitats, spans 3,860 miles and was believed to have been home to more than 400 of the big cats.
The newest figure is a huge drop since the last tiger census in 2004, however experts say the difference may be due to a more accurate method of taking stock of the animals, rather than counting pugmarks.
The recent survey was based on hidden camera footage, which found there to be between 83 and 130 tigers in the region.
"So plus or minus we have around 106 tigers in our parts of the Sundarbans,"
