Duck-billed platypus and spiny anteater {monotreme}| (Monotrema) are small. Monotremes evolved by pedomorphism from juvenile cynodonts that matured quickly. Monotremes lay eggs. Eggs hatch, and infants drink milk from mammary glands. Duck-billed platypus finds buried molluscs and insects by electric potentials.
