Mangrove rivulus
Kryptolebias marmoratus
No photo yet
The mangrove rivulus lives in brackish and marine waters, less often fresh water, from Florida and the Antilles to Brazil, in mangroves, salt marshes and even crab burrows. It withstands wide salinity swings and oxygen-poor water, and survives weeks out of water in moist rotting logs. Most individuals are hermaphrodites that self-fertilise. It reaches 7.5 centimetres.
