Gram-negative, straight rods, motile, presenting 3-12 flagella. Some strains are
monotrichous. No lateral flagella produced on solid media. No swarming on complex
media.
Produces a cell-associated yellow-orange pigment. Luminescence is not a constant
feature. Variable growth in nutrient broth with: 1% & 6% NaCl. No growth in 0%, 8%,
10% or 12% NaCl medium. Growth temperature 25-35 ºC.No growth at 4 or 40 ºC.
Facultatively anaerobic.
 Nonhemolytic on horse blood agar.
Isolated from seawater and marine animals. Sensible to O/129 vibriostatic agent (10 & 150 µg). Resistant to carbenicillin (100 µg)
and ampicillin (10 µg).
Nonpathogenic. Has developed a symbiotic association with the bobtail sepiolid squid, Euprymna scolopes.
