Neofundulus

Neofundulus is a genus of fish in the family Rivulidae. These annual killifish are endemic to the Paraguay, Guaporé, Mamoré and São Francisco basins in Argentina, Bolivia, Brazil and Paraguay.[2][3] They inhabit temporary waters, such as swamps or ponds, that typically are located in open habitats like grassland. Once the water disappears, the adults die, but the eggs that have been laid in the bottom remain, only hatching after several months when the water returns.[3][4]

gollark: For a meme market thing?
gollark: Or can you also not say *why* because of weird legalness?
gollark: Also, seriously, *how* are you legally unable to share the code?
gollark: It's controlled by the team which also run the bot, and I don't think there's a way to run an alternative bot.
gollark: Well, yes, that's fair, in that it kind of mimics them.
