February 10, 2005—Despite its arm-in-arm morning "duets," this monkey species is so little known that it has no name—but not for long. From February 24 to March 3, the New York-based Wildlife Conservation Society will offer the right to name the species to the highest bidder in an online auction.

The nonprofit society discovered the one-foot-tall (30-centimeter-tall), two-pound (one-kilogram) species last year in Bolivia's Madidi National Park. All proceeds from the auction will go toward the enforcement, protection, and management of the park. Home to more plant and animal species than any other South American preserve, Madidi is threatened by "illegal settlements and unsustainable resource extraction," according to the society.
