Definition of vivarium in English:



  • An enclosure, container, or structure adapted or prepared for keeping animals under semi-natural conditions for observation or study or as pets; an aquarium or terrarium.

    • ‘In most research settings, observers sit in the dark watching an illuminated vivarium, peer through gauzy curtains, or observe by means of remote video surveillance.’
    • ‘Because there was no temperature control in the vivarium the animal would have suffered distress as its body heat decreased.’
    • ‘But this iguana is in good condition, which leads me to think it has escaped from a vivarium, rather than having been abandoned.’
    • ‘A small number of test animals for this project are already in the vivarium.’
    • ‘Each individual, in its own compartment of a large vivarium behaves like a dominant, selecting high perches and courting when a female is introduced.’


Early 17th century: from Latin, literally warren, fish pond, from vivus living, from vivere to live.
