Gram-negative coccobacilli, motile by a single polar flagellum. No swarming on
complex media.
Colonies are regular, non-pigmented on marine agar and yellow on TCBS agar
(saccharose positive). Not luminescent.
Can grow in nutrient broth with: 1% NaCl, 6% NaCl, 8% NaCl, 10% NaCl & 12% NaCl.
No growth in 0% NaCl. Temperature  10 -37 °C. No growth at 4 °C or 40 °C.
Grows readily on Marine agar 2216 (Difco), Yeast extract agar and Tryptone soya agar
(Oxoid) containing 1% NaCl and in semisolid seawater agar (stab cultures). No
growth on MacConkey agar.
Susceptible to vibriostatic agent O129.
Isolated from mussels (Mytilus edulis) of the Atlantic coast of Spain.
Unknown.
