Dorsal spines (total): 0; Dorsal soft rays (total):
78-92; Anal soft rays: 64 - 76; Vertebrae: 56 - 61.
Head rectangular in dorsal outline; snout broadly
rounded; eyes dorsally located. Frontal fontanelle
`knife-shaped'; occipital fontanelle very long and
oval-shaped. The `dermosphenotic' and supraorbital
bones become joined in specimens of 80-90 mm SL. Tooth
plates relatively small. Dorsal and anal fins not
confluent with caudal fins. gill rakers relatively
long, slender and distantly set. Openings of the secondary
sensory canals arranged in regular pattern on the
flanks. Habitat: Clarias theodorae
is a demersal species that lives in vegetated areas
in small swamps and streams. It also occurs in delta
areas and lagoons of rivers. Occasionally it is found
in cataracts, hiding under rocks (Teugels 1986). It
is one of the species that is associated with floating
islands that break adrift from peripheral marshes.
Such floating islands may assist in the dispersal
of this species in Lake Malawi. Diet:
It feeds mostly on insects (Coleoptera, ants, Chironomid
larvae) (Teugels 1986, Konings 1990) and occasionally
small fish. Remarks:
Can be told apart from Clarias
The dorsal fin between top and middle in C. theodorae
it is all the way to the caudal tail, and the head
is shorter compared to C. gariepinus.
