History and specifics
The surface of Marris V was predominantly a fresh-water ocean broken up by swamps, savannahs, marshes, and islands. It sported a wide variety of insect life, some as long as 6" inches. Some insects had an almost metallic chitinous covering. Tall reddish vanelike plants covered with sticky juices captured insects, then wrapped shut overnight for digestion. Other plants included yellow flowers and berried bushes. Animals included birds and small ground-nesting rodents. Its ecology was fairly consistent throughout both hemispheres, a rarity among planets.
In 2277, James T. Kirk, security chief Galloway and guards Friedman, Merlino and Pearson from the starship USS Enterprise visited the domed Federation outpost on Marris V, while Hikaru Sulu visited a marshy knoll on the opposite side of the planet and gathered insect specimens for his collection. Decontamination procedures did not eliminate a form of bacteria picked up from the surface, which spread to inflict most of the ship's crew. The bacteria may or may not have evolved on Marris V.
