Species description is based on a single isolate.
Gram-positive cocci, 0.7-1.1 μm in diameter, occuring singly or in pairs, tetrads or
groups. Non-motile. Non-spore-forming. No flagella.
Colonies on Marine Agar are creamy-white, circular, somewhat convex and non-
translucent, glistening surfaces, entire margins and are 2-3 mm in diameter after 3–5
days incubation at 28 ºC. Growth occurs at 10-45 ºC (optimally at 25-30 ºC). Optimal
pH for growth is 7.0-8.0 (range 6-10). Optimal growth in 5-10% NaCl (range 0.5-
25.0% NaCl). Facultatively anaerobic.
Isolated from a sea urchin (Hemicentrotus pulcherrimus) in the South China Sea. Susceptible to ampicillin, carbenicillin, gentamicin,
kanamycin, lincomycin, novobiocin and rifampicin. Resistant to chloramphenicol, nalidixic acid, polymyxin B, streptomycin and
tetracycline.
Undetermined.
