Watch Out for What You Might Get for Christmas

The International Rhino Foundation has come up with a unique gift for under the Christmas tree that stands out from most of the other charity gifts on other -- rhino poop.

From Friday, the foundation will start an auction on eBay for four separate pieces of rhino dung, representing the four species of rhino living in zoos across the United States -- the White Rhino, Black Rhino, Sumatran Rhino and Indian Rhino.

The only rhino species not represented is the Javan Rhino which is so rare with only 60-75 of this species still around that obtaining dung was not possible.

"Everyone knows about rhinos, but not everyone knows that they are disappearing from the earth," said International Rhino Foundation Executive Director Dr. Susie Ellis in a statement.

"It might sound silly, but the money raised by the rhino poop auction will benefit conservation programs, raise awareness, and help us to save rhinos."

The top bid is expected for the poop from the Sumatran Rhino, which is the rarest of the four on offer with only 275 of them estimated to be remaining. The opening bid? $500.
