During the mating process, the female Surinam toad embeds her fertilized eggs directly into specialized pockets in the skin on her back. As the embryos grow, they create small openings, turning her into a living, breathing nursery.

In a sight that seems like something from a science fiction movie, tiny toadlets eventually burst forth from these openings, fully formed and ready to begin their independent lives.

What’s even more unusual is how the males attract mates.

Unlike most toads, which use loud croaks to draw attention, the male Surinam toad produces a sharp clicking sound by snapping the hyoid bone in his throat.

Once paired, the mating duo engages in a remarkable acrobatic display, rising and flipping through the water in arcs.

Each time they flip, the female releases 3 to 10 eggs, which the male carefully embeds into her back. Over the next few days, these eggs sink into the skin, forming a honeycomb-like pattern of protective pockets where the embryos develop.

As the embryos mature, they skip the typical tadpole stage and emerge as fully developed toadlets, less than an inch long. Once they leave their mother’s back, they begin their largely solitary lives.

Afterward, the mother sheds the thin layer of skin used during the birthing process, ready to repeat the cycle again.
