Gram-negative, motile, short rods (0.5 x 1.5 µm). Motile by a single polar flagellum in
liquid medium. Do not swarm on solid media, but lateral short-wavelength flagella
may be produced. Non-sporeforming. No pigments are produced. No luminescence.
Colonies are smooth, circular, off-white and sometimes mucoid on marine agar;
yellow on TCBS agar.

The optimal NaCl concentration for growth is 1 to 6% and it does not grow at higher
than 8% or below 0.3% NaCl. Growth temperature 35 °C, no growth at 4 °C.
Facultatively anaerobe.
Grows on simple mineral media on a variety of organic carbon sources, including
glycine, mannose, and galactose but not D-sorbitol or y-aminobutyrate.

Isolated from larvae and juveniles of the hard clam (Mercenaris mercenaria) , oyster spat (Crassostrea virginica) and adult oyster.
Causes disease in larvae and juveniles of bivalve mollusks. Pathogenic for oyster (Crassostrea virginica, Crassostrea gigas, & Ostrea
