The Vibrios endure basic media that slaughter most intestinal commensals, however they are touchy to corrosive. V. cholerae is a facultative anaerobe, and can experience respiratory and fermentative digestion. It estimates 0.3 micron in distance across and 1.3 micron long with normal swimming speed of around 75.4 +/ - 9.4 microns/sec.
