Gram-negative coccoid rods, 1.0 x 1.7-2.5 µm, motile by means of polar flagella.
Colonies on marine agar are circular with entire margin, non-pigmented, translucent
and luminescent. On TCBS agar colonies are 5-7 mm green or yellow.
The optimal NaCl concentration for growth is 3 to 4%, range 0.5-5%. Growth occurs
at 4 - 30 ºC, optimum 10-25 ºC, pH 5.0-10.5, optimum pH 7.0-8.0. Anaerobic growth.
Isolated from surface seawater in Japan.
