Senegal Bichirs are a species of fish in the Polypterus genus. Senegal bichirs have long bodies with a serrated dorsal fin that goes along their body and meets the caudal fin. Senegal bichirs grow up to about fourteen inches. Their sense of smell is very skilled as their eyesight is very poor. These fish have lungs that make them have to swim to the surface every so often to breathe. Senegal bichirs are also able to survive while outside of water, as long as their skin stays moist.
