Which animal has the most extended period of gestation for an amphibian?

The Surinam toad, also known as the star-fingered toad, has the longest gestation period of any amphibian. This unique species of toad is found in northern South America and is known for its unusual reproductive behavior.

Female Surinam toads have a unique adaptation in which they embed their eggs in the skin on their backs. The eggs then develop into tadpoles, which eventually emerge as fully-formed toadlets. The entire process, from fertilization to hatching, can take up to 8 months, making it the longest gestation period for any amphibian.

The Surinam toad is a fascinating and unusual species that has adapted to its environment in unique ways. Its long gestation period and unusual reproductive behavior are just a few examples of the many remarkable adaptations found in the animal kingdom.
