In the history of the United States, Dwight Sigsbee is recorded as the captain of the U.S.S. Maine when the ship was sunk in Havana Harbor in 1898. The sinking triggered the Spanish-American War.

In the history of oceanography, though, Sigsbee is recorded across the bottom of the Gulf of Mexico. Because he led the first expedition to chart the Gulf floor, in the 1870s, he’s the namesake of several features. They’re all part of the deepest part of the Gulf -- a 300-mile-wide patch known as the Sigsbee Basin or Sigsbee Deep.

Many birds and some primates and other mammals mate with one partner for life, but such monogamy is rare in the animal kingdom. Most animals, including nearly all sea creatures, lead more promiscuous lives, trying to have as many offspring as possible. Having lots of offspring with different mates increases the likelihood of long-term survival for an individual’s genes and its species.
