The researchers found the bizarre tube-lipped nectar bat (
Anoura fistulata) - the first record of this species in the park. Described in Ecuador just a decade ago and known from only three records. It has the longest tongue in relation to its size of any mammal - stretching 8.5 cm to reach into the deepest flowers.
PS: I added the picture of Dorian (villain from The Mask) below it simply because it was the first thing that popped into my mind when I saw the picture.
