Iguana eat bat manure

After two years of research in a cave in northeast Oklahoma, USA, researcher Jim Stout has found that a strange salamanders have a different diet than they once thought.

Stout found blind salamanders living in this cave often eat bat manure. They were originally supposed to live on beetles, shrimp, and this was the first report of an amphibian that lived on bat manure.

" Because bats often do not fully digest food, their droppings are quite nutritious and certainly more calories than tiny shrimps, " Stout said.

Stout also said the group's original mission was to study the population and ecosystem of a cave in Delaware county. There are about 15,000 gray bats living there. "Except for bats and caves that have quite arid habitats, but the salamander population is much more than the cave can contain ."

The researchers also found a significant decrease in soil salamanders when migrant bats were no longer there. Bats only live in caves from May to December.
