A newly named frog species—which had been bottled up for nearly 150 years—has scored a spot on the International Institute for Species Exploration's (IISE's) top ten list of new species named in 2007, released in May 2008.
Scientists declared it a new species when the specimen was rediscovered last year. But the frog and a number of related species are likely now extinct, experts say.
Since the science of taxonomy was refined in the 18th century, scientists have recorded about 1.8 million species on Earth. Most experts estimate that there are close to ten million species on our planet.
