Polypterus senegalus, commonly known as the Senegal bichir, gray bichir or Cuvier's bichir, is an African species of ray-finned fish in the bichir family, Polypteridae.It is a typical example of polypterid fishes, as most of its defining physical features are common across the genus, such as its ancient, lungfish- or arowana-like appearance, the ability to breathe atmospheric oxygen, and its ...

The Bichir Handbook is a book written by science communicator and graphic designer Joshua Pickett from Salisbury, England, [1] about living fossil fishes known as Polypteriformes (bichirs), found throughout west and central Africa, and formerly South America.
The maximum recorded length of P. palmas is 35.3 cm (13.9) inches, although lengths of around 30 cm (11.8 inches) are much more common. [4] It can be distinguished from other similarly-sized bichirs such as Polypterus senegalus and Polypterus polli by its bright gold coloration, speckled pattern, and dark transverse barring.

Polypterus endlicherii, the saddled bichir, is one of the largest species of the Polypterus genus of freshwater fish. Named in honor of botanist Stephan Endlicher (1804–1849), who apparently discovered the species in the fish collection at the Naturhistorisches Museum (Vienna).
The West African bichir or retropinnis bichir (Polypterus retropinnis), is a freshwater fish in the family Polypteridae, [5] is found in the central Congo River basin and Ogooué River in Africa. [6] It is a long, slender fish that grows to a maximum length of about 34 cm (13 in).
Mallon and Anderson postulated that Ankylosaurs and Ceratopsids may have partitioned the herb layer in the Dinosaur Park Formation, or that Ceratopsid feeding height was slightly higher. [21] As well as suggesting that the Ornithopods might have made room for the passing Ceratopsid herds by rising up to avoid ecological competition.
