Panamanian golden frogs

Panamanian golden frogs are native to the Cordillera Mountains in Panama, in wet rainforests or dry cloud forests. Wet rainforest golden frogs live near streams, often in vegetation near to the ground, and while dry cloud forest golden frogs don’t necessarily live near water, they still stay close to the ground. Wet rainforest golden frogs are also bigger. Panamanian golden frogs are active during the day. Golden frogs perform a behavior unique to only a few frogs: hand waving. Hand waving, or semaphore, is only found in frog species that live near rivers, where most sounds are drowned out. Males hand wave to protect their territory, and to attract females. They also stomp and hop around. Females will aggressively wave at males to test whether they back off. If not, she will mate with him. He will stay with her, riding on her back, until she finds a suitable place to lay her eggs: a shallow pool in the shade with rocks or pebbles. She then lays 30-80 eggs and the male fertilizes them. Panamanian golden frogs don’t care for their young. Tadpoles, once they hatch out 9 days later, spend the first 6 months of their life where they hatched, eating algae. Then they leave the water. At this time they are brown and camouflaged, but as they grow they change to yellow and create toxins in their skin. This bright yellow attracts predators, but is also aposematic, serving as a warning that they are poisonous; their skin contains enough toxins to kill 1,200 mice. Panamanian golden frogs chirp and trill, despite the fact that they do not have external ears. Instead, they may hear through their lungs, which vibrate when hit by sound waves. Panamanian golden frogs eat insects and other small invertebrates.
