Okay, so it's Saturday, sue me - life gets busy sometimes. To make up for it, here's an extra cool frog for you, so cool it's named after Charles Darwin!
Rhinoderma darwinii, or Darwin's frog, lives mostly in the beech-tree forests and swamps of central to southern Chile and western Argentina. What makes them particularly fascinating is that when the eggs are ready to hatch into tadpoles Daddy scoops them up in his mouth and keeps them in his vocal pouch - what the heck, he's done serenading Mommy anyway - and keeps them there for a couple more months, feeding them in there on secretions analogous to milk, until they are fully developed into froglets.
Who says guys can't be nurturing, eh? :)
