Northern Surinam toad (SciiFii)

The northern Surinam toad (Pipa americanum), also known as the hole-backed frog, is a species of frog in the family Pipidae that originally did not exist, but has since been created by SciiFii and introduced throughout the rainforests, wetlands, lakes, rivers, and ponds across North America to help boost biodiversity. The closest living relative of the northern Surinam toad is the similarly-looking common Surinam toad (Pipa pipa). The northern Surinam toad is similar in appearance to a mottled brown leaf, and is almost completely flat. Its feet are broadly webbed with the front toes having small, star-like appendages. Specimens of close to 20 centimeters (8 inches) in length have been recorded, although 10–13 centimeters (4–5 inches) is a typical size. The northern Surinam toad has minute eyes, no teeth, and no tongue. It is a predator and scavenger, capturing invertebrates and small fish with its star-fingered hands to eat, or swallowing dead creatures it comes across. Like other Suriname toads, northern Suriname toads are best known for their reproductive habits. Unlike the majority of toads, the males of this species do not attract mates with croaks and other sounds often associated with these aquatic animals. Instead, they produce a sharp clicking sound by snapping the hyoid bone in their throats. The partners rise from the floor while in amplexus and flip through the water in arcs. During each arc, the female releases 3 to 10 eggs, which get embedded in the skin on her back by the male's movements. After implantation, the eggs sink into the skin and form pockets over a period of several days, eventually taking on the appearance of an irregular honeycomb. The embryos develop through to the tadpole stage inside these pockets, eventually emerging from the mother's back as fully developed toads, though they are less than an inch long (25 mm). Once they have emerged from their mother's back, the toads begin a largely solitary life. After giving birth to the new toads, the mother slowly sheds the thin layer of skin that was used to birth them, and can begin the cycle again. The conservation status of the northern Surinam toad is Least Concern due to successful conservation efforts, the northern Surinam toad's wide range and its tolerance to many of the human activities.
