Pseudis paradoxa, commonly known as the paradoxical frog, is a unique amphibian found in the tropical regions of South America. This species is notable for its unusual life cycle, where the tadpoles can grow to be much larger than the adult frogs. They typically inhabit freshwater environments like ponds and swamps. The adult Pseudis paradoxa is characterized by its greenish-brown skin and long limbs, which help it swim efficiently. These frogs are primarily carnivorous, feeding on insects and other small invertebrates. Their distinctive growth pattern and habitat preferences make them an interesting subject for ecological studies.
