An inflatable real frogDescription:
Breviceps namaquensis or the Desert rain frog, otherwise known as the Namaqua rain frog is the strange individual shown below.
They are a burrowing frog, spending most of their time under ground as do many frogs that live in arid environments. When they are threatened they inflate their body and make a squeaking which sounds something like a kids toy. This is supposed to intimidate, I'll let you be the judge of how effective it is. Watch it here:
Breviceps namaquensis is known from the arid west coast of South Africa. I can't seem to find any records that extend into Namibia, but I suspect that might be sampling error or a lack of knowledge on my part because species other than humans don't tend to pay much heed to political boundaries.
Species: Breviceps namaquensis
