Gram positive cocci, 0.8 - 1 μm, non-motile, non-sporing. Occur singly or in clusters.
Form S-type colonies, non-pigmented, 5-7 mm diameter & haemolytic. Facultatively
anaerobic, 26-37 ºC. Can grow on 15% NaCl agar. Other media: Trypticase Soy Agar
± 5% sheep blood, Chapman (selective medium with 75 g/l NaCl & mannitol).

Isolated from dolphins. Sensible to Novobiocin.
Isolated from purulent skin lesions of captive dolphins; uncertain pathogenicity.
