    Structure and identification

    Small bacterial cells require microscopy for direct observation. Light emission is a physiological property, not a visible body-color diagnosis.

    Scientific source ↗

    Habitat and range

    Marine environmental phases and specialized host-associated sites provide distinct growth conditions.

    Scientific source ↗

    Nutrition and metabolism

    Organic substrates support metabolism. Conditions inside a host can differ substantially from those in surrounding seawater.

    Scientific source ↗

    Biological activity

    Chemical signaling and population context influence light production and other behaviors relevant to colonization.

    Scientific source ↗

    Reproduction and life cycle

    Cell multiplication and repeated opportunities for host colonization connect free-living and symbiotic phases.

    Scientific source ↗

    Geographic distribution

    Environmental and host-derived strains have documented collection localities. The origin of one experimental strain does not define the full range.

    Ecological role

    The well-studied squid association demonstrates a microbial contribution to an animal's light-producing system.

    Distinctive adaptations

    Bioluminescence, environmental sensing and colonization traits help explain the model symbiosis.
