The giant Palouse earthworm

Fans of the giant Palouse earthworm are once again seeking federal protection for the rare, sweet-smelling species.

The worm has been seen only four reported times in the past 110 years, but supporters contend it is still present in portions of eastern Washington and northern Idaho.

The worm can reach 3 feet in length, is white in color and reportedly possesses a unique lily smell.

Environmental groups are asking the U.S. Fish and Wildlife Service to protect the worm as an endangered species.

The Bush administration rejected an earlier petition, but supporters hope to have better luck with the Obama administation.
