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 an "alima" larva, while in Gonodactyloidea, a "pseudozoea" develops into an "erichthus". A single fossil stomatopod larva has been discovered, in the Upper Jurassic Solnhofen lithographic limestone. The life cycle of krill is relatively well understood, although there are minor variations in detail from species to species. After hatching, the larvae go through several stages called "nauplius", "pseudometanauplius", "metanauplius", "calyptopsis" and "furcilia" stages, each of which is sub-divided into several sub-stages. The "pseudometanauplius" stage is exclusive to the so-called "sac-spawners". Until the "metanauplius" stage, the larvae are reliant on the yolk reserves, but from the "calyptopsis" stage, they begin to
