Dinosaur or gray bichir (scientific name Polypterus senegalus). These fish are most commonly spotted in aquariums. They’re also known as swamp dragons, dinosaur eels, and reed fish.

A Polypterus senegalus fish walks across a sandy substrate. The bichir fish use their fins and body together to move across land, but they’re better at it if they’re raised outside of water, a ...

Unusual fish that walk and breathe air turn out quite differently when raised on land, rather than in water. Their development holds clues to a pivotal moment in animal evolution, when the first ...

To learn more about what happened, scientists investigated the bichir (Polypterus senegalus), a modern African fish that has lungs for breathing air, and stubby fins it can use to pull itself ...

The authors of the new study, three scientists at McGill University in Montreal, studied fish called bichirs (Polypterus). Bichirs are the living remnants of a very old lineage of fishes, which ...

The modern fish species called Senegal bichir (Polypterus senegalus) normally swims in African rivers. But the elongated fish possesses both gills and lungs and can walk on land if it has to.

To better understand the evolutionary pressures on those early tetrapods, lead author Emily Standen, now at the University of Ottawa in Canada, and her colleagues took juvenile bichir (Polypterus ...
