Polypterus ornatipinnis, or the ornate bichir, is a freshwater fish native to the Congo River Basin. It features elongated, snake-like bodies, distinctively patterned with black and yellow markings. This nocturnal predator has primitive lungs, allowing it to breathe air, and is known for its unique finlets along its back.

Polypterus ornatipinnis, commonly known as the Ornate Bichir, is native to Central and Western Africa. Specifically, it is found in the Congo River Basin, which spans several countries including the Democratic Republic of the Congo, Republic of the Congo, and surrounding regions.

Polypterus ornatipinnis inhabits freshwater environments, typically favoring slow-moving or stagnant waters such as swamps, marshes, and floodplains. The regions are usually warm with tropical climates, featuring high humidity and temperatures ranging from 24°C to 28°C (75°F to 82°F).

The Ornate Bichir is a bottom-dwelling species that often resides in areas with abundant vegetation and muddy substrates. This habitat provides ample cover and hunting grounds for its diet, which primarily consists of small fish, crustaceans, and insects. As an air-breathing species, it is well-adapted to low-oxygen environments typical of its habitat.
