Animal
Animals are a major group of multicellular, eukaryotic organisms of the kingdom Animalia or Metazoa. Their body plan eventually becomes fixed as they develop, although some undergo a process of metamorphosis later on in their life. Most animals are motile, meaning they can move spontaneously and independently. All animals are also heterotrophs, meaning they must ingest other organisms or their products for sustenance.

“The animal is ignorant of the fact that he knows. The man is aware of the fact that he is ignorant.”
—Victor Hugo (1802–1885)
“The hounding of a dog pursuing a fox or other animal in the horizon may have first suggested the notes of the hunting-horn to alternate with and relieve the lungs of the dog. This natural bugle long resounded in the woods of the ancient world before the horn was invented.”

“There is no mystery in the luminous lines
Of that high, animal face
The smile, sad, humouring and equal
Blesses without obliging
Loves without condescension;”
