Dorsal spines (total): 0; Dorsal soft rays (total):
62-77; Anal soft rays: 52 - 57. Diagnosis: long and
narrow, "knife-shaped" frontal fontanel
(Ref. 248, 81644), 2.5-3.0 times as long as wide.
Tooth plates remarkably broad; median vomerine tooth
plate length strikingly shorter than premaxillary
length. Vomerine tooth band very short, length 2.0-5.0%
HL (mean 3.3), clearly shorter than premaxillary tooth
band. Head rectangular in dorsal outline, relatively
large (HL 25.3-27.6% SL, mean 26.4) and wide (width
18.6-20.9% SL, mean 19.8). Supraorbital and "dermosphenotic"
never sutured; reduced suprabranchial organ. Pectoral
spine serrate only along anterior margin; flank neuromasts
arranged in a regular pattern; postorbital bones not
in contact; eyes laterally positioned, interorbital
width 44.5-49.0% HL, mean 47.3; 14-16 rakers on 1st
gill arch. Diet: Large individuals
feed mainly on other fishes (especially cichlids),
while smaller individuals mainly feed on insects.
dark reddish brown on back and flanks; ventrum and
lower parts of paired fins pale. Etymology:
Named in memory of Peter
Ian Rupert MacLaren (ca. 1919-1956), who used his
position as Fisheries Development Officer of Nigeria
to collect fishes for the British Museum, including
type specimen of this catfish (from Cameroon) in 1948.
He died from wounds inflicted by a crocodile in what
is now Zambia. Remarks:
Clarias maclareni is a critically endangered
species of catfish in the family Clariidae. It is
endemic to Lake Barombi Mbo in western Cameroon. It
is currently threatened because of pollution and sedimentation
due to human activities, and potentially also by large
emissions of carbon dioxide (CO2) from the lake's
to Lake Barombi Mbo, western Cameroon.
