Rarest Tree Frog Spotted

The rarest tree frog in the world, once thought to be extinct, has been spotted by a researcher in Costa Rica.

The Isthmohyla rivularis was thought to have died-out some two decades ago, but a scientist spotted a male last year, leading to more research.  Scientists have since discovered a female and several more males, suggesting the species is breeding nicely, though the frog remains a rarity.  The female was carrying an egg sac.
