In Monteverde, Costa Rica, I once witnessed a mass
mating of thousands of yellow frogs (not the same as the frog
above). They came out of nowhere, mated , and disappeared within
a few hours. Only the males were bright yellow, and they only
held that color during the mating frenzy. If they were disturbed
they changed back to brown in a matter of seconds. This is what
every square meter of their swamp looked like while they were
mating.

Below are a mating couple only mildly disturbed
by my presence; the second photo below shows the male uncomfortable
about being watched, beginning to change to brown. I guess he
wanted a little privacy. |
