Get ready to be amazed by one of the most amazing things I have ever seen an animal do. The Surinam toad (Pipa pipa) is an amphibian that gives birth through its back, which is the opposite of how most animals do it.
This one-of-a-kind animal lives in the rainforests of South America. It has evolved an amazing trait that makes it one of the most interesting examples of evolution in nature.
The unique way that the Surinam Toad reproduces
When the female Surinam toad wants to mate, she puts her fertilized eggs right into special pockets in her back skin. She becomes a living, breathing nursery as the embryos grow by making small holes in her.
Eventually, tiny toadlets that are fully grown burst out of these holes, ready to start their own lives. It looks like something from a science fiction movie.
Strange Mating Behavior
What’s even stranger is how the males find mates. As a way to get people’s attention, most toads make loud croaks. But the male Surinam toad snaps the hyoid bone in his throat, making a sharp clicking sound. Once they are paired up, the mating pair does amazing acrobatics by rising and flipping through the water in arcs.
The female lays three to ten eggs every time they flip, and the male carefully inserts them into her back. In the following days, these eggs will sink into the skin, creating a honeycomb-like pattern of safe pockets where the embryos can grow.
