the Wood Frog Eggs Hatched!
After a rather cold three weeks, the Wood Frog eggs have finally hatched! The tiny tadpoles look overstuffed, since they have some leftover yolk in their bodies which means they don’t need to eat for the first few days after hatching.
Being a tadpole is the second stage in their metamorphosis (a word that means that means a change or transformation). As a tadpole, Wood Frogs will eat mostly algae and rotting plants, and breathe oxygen with gills. Amazingly, when they metamorphose into adult frogs in summer, they switch from gills to lungs and become carnivores, eating mostly insects and other invertebrates.
