Photos: Top 10 new species

Each year, Arizona State University's International Institute for Species Exploration releases a top 10 list of the most interesting new species from the past year.

This weekend, the 2009 list came out. The top 10 includes a self-destructing palm, the longest insect, a tiny seahorse, the smallest snake, and caffeine-free coffee beans.

To be especially accurate, the institute does not say these are newly discovered species. That would be very Western-scientist-centric and offensive to local populations who may know about these creatures for generations. Instead, the new top 10 winners are chosen from the "thousands of species fully described and published in calendar year 2008," according to ASU's site.

First on the list is the Tahina Palm, or Tahina spectabilis. There are fewer than 100 known individual trees in northwestern Madagascar. This species grows nearly 60 feet tall, according to London-area Royal Botanic Gardens, Kew. After 30 to 50 years, the palm produces seeds in a once-in-a-lifetime flowering.

"This plant flowers itself to death, producing a huge, spectacular terminal inflorescence with countless flowers. After fruiting, the palm dies and collapses," according to ASU's site. "Soon after the publication of the species, seeds were disseminated throughout the palm grower community, raising money for its conservation by the local villagers, and it has become a highly prized ornamental."
