How many humans were saved aboard Noah's Ark in 1 Peter?

First Peter says that eight people were saved aboard Noah's Ark.

First Peter 3:20 refers to the eight souls or persons who were brought safely through the flood. This count corresponds to Noah, his wife, Noah's three sons, and the three wives of those sons. Genesis describes the same household entering the Ark, although the total of eight is stated explicitly in the New Testament passage.

The number is easy to miscount because Genesis names Noah and his three sons but does not give the names of the four women. The wives are nevertheless included in the account, and their presence produces the traditional total of eight human survivors.

This question is specifically about the human passengers, not the animals or the number of people mentioned in a particular artistic retelling. First Peter uses the flood story in a discussion of salvation, while Genesis provides the narrative setting and family details.
