Each year during the monsoon, these amazing little frogs show up. They’re often mistaken for poisonous toads due to their superficial similarity and typically green color. It’s a Couch’s Spadefoot, a small and harmless species that spends much of its time underground. Its name is literal: to help with the underground lifestyle, it has hard protrusions on each hind leg to help dig in.
They also have, unlike most amphibians, cat-eyes (this one has them wide open, however). If you see one, you can ignore it as it’s not at all dangerous, but still keep your dog from eating it.
This Red-Eyed Treefrog was really dark compared to others I’d seen! Found on a nighttime walk in the Guatemalan rainforest.
A Glass Frog stays with its eggs, as seen from below the leaf on a night hike in Guatemala. Within each egg, a tiny tadpole can be seen.
