Three Bizarre Frog Facts: Part 3

Bizarre Frog Fact #3: This Frog Can Hold 50% Of Its Weight In Water.

The Water-Holding Frog, Cyclorana platycephala, is a weird Australian frog that lives in the desert and has a real thing for H2O. Whenever there's a severe water shortage (and hey, it's the desert...there's pretty much always a water shortage), it:
  1. Stores ridiculous amounts of water (up to 50% of its weight!) in its bladder and pockets in its skin - this water is acquired when there's a sudden downpour of rain,
  2. Uses its feet like shovels, and tunnels underground into the sand,
  3. Secretes a layer of mucus out of its skin, and then hardens the outermost layer, forming a tough outer layer of dead skin - a bit like wrapping itself up in Glad-Wrap,
  4. Stays there until there's enough rain to safely come out again. This can take years.

Nifty, eh?

  1. D=
    50% water weight in its bladder
    sounds both painful and magical

  2. Bladder AND 'skin pockets' as well.


    no actually, that makes it sound MORE painful.
