Overview
Pterosturisoma microps is the only species
Species
In biology, a species is one of the basic units of biological classification and a taxonomic rank. A species is often defined as a group of organisms capable of interbreeding and producing fertile offspring. While in many cases this definition is adequate, more precise or differing measures are...

Family (biology)
In biological classification, family is* a taxonomic rank. Other well-known ranks are life, domain, kingdom, phylum, class, order, genus, and species, with family fitting between order and genus. As for the other well-known ranks, there is the option of an immediately lower rank, indicated by the...

Quotations

Adam and Eve had many advantages, but the principle one was that they escaped teething.

Mark Twain, Pudd'nhead Wilson's Calendar

Adam and Noah were ancestors of mine. I never thought much of them. Adam lacked character. He couldn't be trusted with apples. Noah had an absurd idea that he could navigate without any knowledge of navigation, and he ran into the only shoal place on earth.

Mark Twain, Speech, November 9, 1901. Reported in The New York Times, November 10, 1901

“Adam knew Eve his wife and she conceived.” It is a pity that this is still the only knowledge of their wives at which some men seem to arrive.

F. H. Bradley, Aphorisms, no. 94 (1930)

Adam, man's benefactor — he gave him all he has ever received that was worth having — Death.

Mark Twain Notebook, 1902-1903

Adam was but human — this explains it all. He did not want the apple for the apple's sake, he wanted it only because it was forbidden. The mistake was in not forbidding the serpent; then he would have eaten the serpent.

Mark Twain, Pudd'nhead Wilson|Pudd'nhead Wilson (1894)

After all these years, I see that I was mistaken about Eve in the beginning; it is better to live outside the Garden with her than inside it without her.

Mark Twain, Extracts from Adam's Diary|Extracts from Adam's Diary (1904)

Ever since Eve gave Adam the apple, there has been a misunderstanding between the sexes about gifts.

Nan Robertson, New York Times|New York Times (November 28, 1957)

It all began with Adam. He was the first man to tell a joke — or a lie. How lucky Adam was. He knew when he said a good thing, nobody had said it before. Adam was not alone in the Garden of Eden, however, and does not deserve all the credit; much is due to Eve, the first woman, and Satan, the first consultant.

Mark Twain, Notebook, 1867

Let us be thankful to Adam our benefactor. He cut us out of the 'blessing' of idleness and won for us the 'curse' of labor.

Mark Twain, Following the Equator, Pudd'nhead Wilson's New Calendar
