V. splendidus includes biotypes I, II and a unnamed biotype (Reichelt at al. 1976).
Historical synonyms: Photobacter splendidum Beijerinck 1900, Beneckea splendida

Gram-negative straight or curved rods, motile. Not swarming on complex media.
Nonspore-forming. Bioluminescence is present in biotype I.
Grows at 18 -30 ºC. Weak or no growth at 4 and 35 ºC. Grows in media with 1 to 8%
NaCl. No growth in the absence of NaCl. Facultatively anaerobic.
Isolated from marine fish and seawater. Susceptible to vibriostatic compound 0/129.
May cause vibriosis in fish, oysters, mussels, and scallops.
Pathogenicity of V. splendidus biovar II was proved by experimental infection of Japanese oysters larvae.
