The great science of life consists in the knowledge of ourselves, the laws of our existence, the relations we sustain to each other, to things and beings around us, to our ancestry, to our posterity, to time, to eternity, to our heavenly Father, and to the universe.

The amphibian reproductive system includes testes in males and ovaries in females.

Reproduction is often external in frogs, but often internal in caudatans and caecilians.

Reproduction often requires water and involves a metamorphic stage that is especially complex in anurans.

Finally, the amphibian endocrine system, as is typical in the vertebrates, plays a crucial role in regulating various physiological processes, including growth, metabolism, and reproduction.

Key endocrine organs include the pituitary gland, thyroid gland, and adrenal glands.
