Oddly enough, most of the references to "Triton" in the astronomical literature in the late 19th and early 20th centuries are to the name of a supposed Martian canal.
Triton is unique among all large moons in the solar system for its retrograde orbit around the planet (i.e., it orbits in a direction opposite to the planet's rotation).
If Triton is a candidate for extra-terrestrial life, it would not be like life on Earth, owing to the extreme cold, the nitrogen and methane environment, and the fact that the moon lies within Neptune's dangerous magnetosphere.
