After having produced aquatic animals of all ranks and having caused extensive variations in them by the different environments provided by the waters, nature led them little by little to the habit of living in the air, first by the water's edge and afterwards on all the dry parts of the globe. These animals have in course of time been profoundly altered by such novel conditions; which so greatly influenced their habits and organs that the regular gradation which they should have exhibited in complexity of organisation is often scarcely recognisable.
I lived in Rome for about five or six months during Life Aquatic.
Evidence of this [transformation of animals into fossils] is that parts of aquatic animals and perhaps of naval gear are found in rock in hollows on mountains, which water no doubt deposited there enveloped in sticky mud, and which were prevented by coldness and dryness of the stone from petrifying completely. Very striking evidence of this kind is found in the stones of Paris, in which one very often meets round shells the shape of the moon.
Animal abuse is rampant in the U. S. , right under everyone's eyes, for the entertainment of the public. The brutal confinement and pain of training methods of wild animals in the circus, the aquatic and theatrical shows, leads to retaliation by the animals. Eventually they find the right time to strike out, and they will.
Aquatic animals suffer from the disadvantage that they cannot scream when in pain, so we find it hard to gauge the degree of their agony. If fish could scream, angling purely for sport would be outlawed without delay.
