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
Müller's larva described larval forms of many phyla. Müller's larva Müller's larva or Mulleria is a larva of some Polycladida. It has 8-fold symmetry and is somewhat like a ctenophore. Müller’s larva is ciliated and has several paired and unpaired lobes. The cilia on the lobes are longer than cilia on the rest of the body. At the anterior and posterior ends of the larva are tufts of longer cilia (apical and caudal). The apical tuft originates from the apical organ, a sensory structure associated with the central nervous system. It is named after Johannes Peter Müller (1801-1858), a German physiologist who
