Komodo dragons are real dragons. They are similar to monitors, but they have a few differences. As food is broken down in their stomach, the methane that is produced is carried to special glands in the throat. These glands then can be emptied through tubes under the dragons tongue. The dragon’s methane is different from the methane released by other animals. Certain properties cause it to ignite when it comes in contact with oxygen. Large male komodo dragons in the wild can release up to three burst that last 3 to 5 seconds. The glands are removed in zoo animals due to the danger of fire breathing.

One Komodo in a London zoo was overlooked in 1963 and did not have the methane glands removed. It killed another Komodo dragon male that was after one of the females. A zoo keeper suffered third degree burns during the capture of the large dragon. Sadly the dragon was put down before the methanectomy could be performed.
This sounds pretty off the wall. Found it on another forum.

Is this rediculous or real?
