As an addendum to my Raise Giant Frogs nightmare post of a few days ago, here is a phenomenon of nature which I hitherto knew nothing about.
When you startle a frog, it screams.
Sometimes it sounds like a prolonged cat-yowl, or a balloon with the air slowly leaking out of the opening.
One wonders at the purpose of the scream, but it would seem to be either self-protective (the people in this video aren't necessarily being very nice to the frogs, and in some cases are actually provoking them) or a general alarm to the whole frog-pond. Human alert - whoop, whoop!
I never knew frogs screamed before, or that frogs could play video games, lunging at screens that have rapidly-moving buglike images on them. Clever? Yes. . . but not TOO clever. Frog might swallow the whole damn thing.
