Frogs Predict Pregnancy

This piqued my interest enough to share.
Here is an interesting fact I heard on PBS this afternoon.
The segment was actually about the extinction of different species in the world. One of the commentators told of amphibians being the first to go. She mentioned a few places that used to be abundant with frogs and now nary a frog can be found in those places.
She went on to talk about a type of frog that was used as a pregnancy test with great success. And unlike mice and rabbits, the frogs did not have to be killed to get the results.
Anyway the frogs were shipped round the world for this use. Now they suspect this type of frog carries a fungus that is responsible for the death of many frogs.
Damn.

For more detail on this, here is a link…..
