New Species! Leaping lemurs, sea creepies, a gecko in gay Paris

New species popping up all over the place!

From the treetops of Indochina and Sundaland will now be leaping three certifiably separate species of flying lemur, or "colugo." The colugos had been thought to comprise only two species, the Sunda colugo and the Philippine colugo. But upon comparison of DNA between Sunda colugos from mainland Indochina, Java, and Borneo, researches discovered each region had a unique species, having diverged as much as five million years ago.

Colugos glide using a membrane stretched between their appendages, like a flying squirrel. Apparently, their diversification "might be explained by the colugos' unusual way of getting around. While they have the most developed gliding membrane of any mammal, they are nearly helpless on the ground, leaving them incapable of crossing large open spaces that lack trees." Groups could easily have isolated themselves and had to settle down and speciate.

That's not to disparage these floating fellows, since they are the closest living group of mammals to ours, the primates.

Scientists from the seven year old Census of Marine Life met recently to discuss the 120,000 undersea species they'd documented thus far, including newly discovered blind lobsters, giant oysters, sea spiders the size of dinner plates, and the progenitor of many deep sea octopodes. Creepy pics, as usual, at Natty G.

Lastly, a new gecko with a dramatic tale, and the recently rediscovered pygmy tarsier from Indonesia, feared to be extinct since the 1920s.
