Golden toad led bachelors to attack amplectant pairs and form what has been described as a "writhing masses of toad balls". During the 1977 and 1982 seasons, males outnumbered females by over 8 to 1 at breeding pools. Each toad couple produced 200–400 eggs each week for the six-week mating period, with each egg approximately 3 mm in diameter. The eggs of the golden toad, black and tan spheres, were deposited in small pools often no more than one-inch deep. Tadpoles emerged in a matter of days, but required another four or five weeks for metamorphosis. During this period, they were highly
Crustacean larva and hatch with a full complement of adult appendages with the exceptions of the uropods and the first pair of pleopods. The larvae of the Achelata (slipper lobsters and spiny lobsters) are unlike any other crustacean larvae. The larvae are known as "phyllosoma", after the genus "Phyllosoma" erected by William Elford Leach in 1817. They are flattened and transparent, with long legs and eyes on long eyestalks. After passing through 8–10 phyllosoma stages, the larva undergoes "the most profound transformation at a single moult in the Decapoda", when it develops into the so-called "puerulus" stage, which is an immature form
