The livebearer

This species was first described in 2019.

Killifish, livebearers, and splitfins — small-bodied freshwater fishes, many of them from a single lake, spring, or seasonal pool.

Range and habitat

Rio Concepcion Topminnow is recorded from Mexico.

GBIF currently lists 6 occurrence points. Those points follow where people logged the taxon — museum drawers and surveys included — not a closed range boundary.

Pins are Wikidata “endemic to” fields. Orange dots, when present, are GBIF occurrence tiles — survey bias included.

Breeding

Livebearers drop free-swimming young. Many species occupy springs, lakes, or ditches with little room to retreat.

Small desert or forest fishes in this order live in water that can vanish. The egg bank, if there is one, is the only reserve.
