FAQ
Frequently Asked Questions
Biologically, yes, humans are viviparous mammals. However, the term 'live-bearer' is rarely applied to mammals in common usage; it is a technical term most frequently used for fish and some reptiles in biology and aquarium hobbies.
'Viviparous' is the precise scientific adjective meaning 'giving birth to live young'. 'Live-bearer' is the common noun form used to name the animals that have this characteristic, especially in non-technical or hobbyist contexts.
True live-bearers (viviparous) do not lay eggs; the young develop internally. Some species called 'ovoviviparous' retain eggs inside the body until they hatch, then give birth, and are also often grouped under the term 'live-bearer' in casual use.
The hyphen clarifies that 'live' modifies 'bearer' as a single unit. Without it, 'live bearer' could be misread as a person who is currently alive and bearing something. The hyphen signals the compound noun meaning 'a bearer of live young'.
