abstract:The Senegal bichir, Polypterus senegalus, also known as the gray bichir and Cuvier's bichir, is sometimes called the "dinosaur eel" (a misnomer, as the creature is not an eel) and also known as "dragon fish" at many local pet chains. It is a prototypical species of fish in the Polypterus genus, meaning most of its features are held across the genus.
