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.

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.
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 ...
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).
Polypterus weeksii, the mottled bichir, is a fish in the family Polypteridae found in the central basin of the Congo River. [2] It grows to about 54 cm in head-to-tail length. [ 2 ]
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 mokelembembe is a species of the fish genus Polypterus, found in the central basin of the Congo River. [2] It was once considered a morph of the closely related Polypterus retropinnis, but was given species status in 2006 with a description that reclassified both fishes. [3]
