"This is probably the coolest fish around"

--Per Scott Taylor, who discovered and characterized a fish in Belize that can live out of water for months at a time.

The fish, whose scientific name is Rivulus marmoratus, can grow as large as three inches. They group together in logs hollowed out by insects and breathe air through their skin instead of their gills until they can find water again. ...

Surviving on land is not the only unusual behavior exhibited by the fish. They have both testes and ovaries and essentially clone themselves by laying their own, already fertilized eggs.

"This is probably the coolest fish around, not only do they have a very bizarre sex life, but they really don't meet standard behavioral criteria for fishes," said Taylor in a summary of his paper.
