The killifish

It grows to 5 cm (2.0 in) TL.

New World rivulids include annual killifish that survive a dry season as eggs in mud, and non-annual forest-stream forms.

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

Range and habitat

Hypsolebias magnificus is a killifish in the family Rivulidae native the Middle São Francisco River basin in Brazil.

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

Breeding

Annual rivulids hatch, breed, and die in one wet season; the eggs wait in the mud. Non-annual species live in forest streams year-round.

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.

In crisis
