The Charles Darwin frog, found only in the Andaman Islands, has a unique and surprising mating behavior: they mate and lay their eggs upside down!
They hang upside down on the walls of tree cavities, completely out of water, making them one of the most unusual frogs in the world.
The male frogs get into fierce fights, using kicks, punches, and even biting to win over a mate.
This discovery shows how much we still have to learn about frogs and the importance of protecting their habitats from deforestation and pollution.
