The town clerk, Emily Butler, told Canadian news service NTV that the blue whale carcass washed up on the town's boardwalk last week is decaying and filled with methane gas, which could lead the whale to explode.

The whale is more than 80 feet long and filled to twice its normal size with methane, she said, noting that if the town pushes it out to sea, the explosion could pose a danger to passing ships.

Whale explosions have been documented before. In 2013, a graphic video surfaced of a dead sperm whale exploding while being studied by a scientist.

Butler said the small town is seeking help in disposing of the whale.
