Named after its Type locality
of Cameroon. Possess accessory breathing organs which
allow survival for long periods out of water. Can
'walk' on land using its pectoral spines as support.
Description: No dorsal spine. Dorsal
spines (total): 0; Dorsal soft rays (total): 69 -
87; Anal soft rays: 52 - 70; Vertebrae: 56 - 61. Head
rectangular dorsally; snout extremely broadly rounded;
eyes more laterally placed. Frontal fontanelle long
and narrow; occipital fontanelle long and oval-shaped.
Supraorbital and `dermosphenotic' bones separated
in specimens over 200 mm SL. Tooth plate extremely
broad. Pectoral spine slender; outer side showing
strong downward serrations. Suprabranchial organ well
developed. Openings of the secondary sensory canals
show a regular pattern. Diet: Data
on the diet of C. walkeri (=C. camerunensis)
showed larvae of mayflies, chironomids, and caddis
insects to be the main food of small and middle-sized
specimens. Remarks: According to
Teugels (1986) this species should be assigned to
the subgenus Brevicephaloides because of
the shape of its head, being short and broad which
coincides with this genus.
