Individuals united in amplexus (a sexual reflex found in anuran amphibians) perform flips, each of which lasts several seconds. At a certain stage of this figure, the female lays eggs, which are immediately fertilized by the male and glued by him on the female’s back. Rich in blood vessels, the female’s skin forms special pockets around the glued eggs. After 10 days, the eggs are completely overgrown with skin - they develop in the closed pockets at a depth of 15 mm.
