Crowned Tree Frog (Triprion spinosus), found in Costa Rica.

Spiny-Headed Treefrog: This species’ most immediately notable characteristic is the spines protruding from their head. Like most other frogs, the male finds a suitable place to lay eggs, (in this case, a temporary pool, tree hollow, or bromeliad filled with water,) and calls for the female. They lay a few eggs over the water, and return approximately every seven days to continue breeding. Since the pools are small and tend to lack food, the female will care for the young on nights when the male is not present, resting semi-submerged in the water and laying unfertilized eggs as the tadpoles nibble at her before voraciously devouring their fresh meal.
