Description
The Mangrove Rivulus is a unique killifish renowned for its amphibious lifestyle, capable of living both in water and on land, and breathing air through its skin. It is also one of the few known self-fertilizing hermaphroditic vertebrates. This small, adaptable fish thrives in mangrove swamps and coastal areas, tolerating a wide range of salinity and temperature.
