DARWIN’S FROG (Rhinoderma darwinii): A VULNERABLE SPECIES



Today’s “species of the day” is a curious amphibian found in Chile and neighboring Argentina, with a peculiar triangular shape of its head and a cylindrical dermal appendage at the tip of the snout.  Most remarkable is its strange reproductive strategy of brooding egg and larvae within its mouth, from where the newly metamorphosed froglets step out.
Populations of this frog, discovered by Darwin in his famous travel around the World, are in decline, to the point that it is now considered in the conservation category of “Vulnerable”. Most probably, the causes of the declines are related to human activities, of which deforestation and several factors associated with climate change are among the main culprits.
