Day 2 of #froggyfall - Old book / Blue poison dart frog (Dendrobates tinctorius "azureus")These frogs are found only in the rainforests of Suriname and northern Brazil. The black spots on their bodies are unique to each individual, so no two frogs have the exact same pattern!

Day 3 of #froggyfall - Herb garden / Common parsley frog (Pelodytes punctatus)This frog can be found from Spain to Northern France. Common parsley frog tadpoles can reach up to 6.5 cm in length, which is longer than they normally are as adults (3.5 - 4.5 cm)!
