Meet the backpack frog.
Boulanger's backpack frog, or Cryptobatrachus boulengeri, is a small frog from Colombia with a very unusual adaptation.
While most frogs release their eggs into the water, where babies develop from tadpoles into baby frogs, backpack frogs belong to a family of frogs called Hemiphractidae that's unusually protective. They stick their eggs onto their backs, where the babies will stay until they're tadpoles or even little froglets.
A photo shared by Amphibian & Reptile Conservation shows just how dedicated these frog moms are.
