Physical characteristics
Elongated, eel-like body covered in thick, diamond-shaped ganoid scales. Features a distinct row of numerous small finlets along the back rather than a single continuous dorsal fin. Coloration includes a yellowish-brown background heavily patterned with striking black saddles, blotches, and reticulations along the body and fins.
Habitat & distribution
Inhabits shallow, slow-moving freshwater rivers, swamps, and floodplains in tropical Africa, specifically native to the Congo River basin.
Behavior
Solitary and largely nocturnal or crepuscular. Spends much of its time resting on the substrate, though it frequently rises to the surface to gulp air.
Diet
Carnivorous. Feeds on smaller fish, aquatic insects, crustaceans, and amphibians, primarily using its keen sense of smell to hunt in low-visibility waters.
Reproduction
Egg-scatterer that typically spawns during the rainy season among dense aquatic vegetation. Parents do not provide post-spawn parental care.
Ecological role
Acts as an opportunistic apex benthic predator in its native freshwater ecosystems, helping to regulate local populations of smaller fish and aquatic invertebrates.
Similar species
Other Polypterus species such as Polypterus endlicheri, which can be distinguished by different banding patterns and facial markings.
Identification tips
Easily identified by the distinctive high count of dorsal finlets (usually 9 to 14) and the bold black and yellow-brown ornate patterning across the entire body.
Interesting facts
Bichirs possess a modified lung that allows them to breathe atmospheric air, enabling them to survive in oxygen-depleted waters and even crawl short distances over land during the wet season.
