Parameters of development have been analyzed in all offspring (1633 ind.) from the same spawn of one pair of common toads under conditions of laboratory rearing, with natural elimination being reduced to a minimum. The results show that the range of developmental options for the species is much wider than it follows from the standard tables of development.
