Hypsolebias splendissimus
Hypsolebias splendissimus is a killifish in the family Rivulidae (order Cyprinodontiformes), recorded as Critically Endangered.
The killifish
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
No country pin is stored for Hypsolebias splendissimus on this catalog. That is a missing field, not proof the animal has no range.
GBIF currently lists 4 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
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
Hypsolebias splendissimus is Critically Endangered on this catalog because that is the IUCN category stored on Wikidata. Confirm the official criteria and any later count on iucnredlist.org.
