Are fish originals?

Fish

Terrestrial animals are originals. Are aquatic animals also originals? To begin the answer, photographs of 158 different breeds of fish were inspected. Each one was an original. There were no duplicates. That suggested that all fish are originals and the probability of being wrong would be 1/2^158, 1 chance in about a duodecillion. See the figure above.

To diminish the variability and thereby increase the probability of finding a duplicate, a haphazard sample of 25 guppies (Lebistes reticulatus) was examined. All were originals. There were no duplicates. That suggested that all guppies are originals and the probability of being wrong would be 1/2^25, 1 chance in about 33 million. See the figure below.
