Description:
Dorsal spines (total): 2; Dorsal soft rays (total):
4-5; Anal spines: 0; Anal soft rays: 9 - 12; Vertebrae:
36 - 38. This species is generally more pallid and
less conspicuously marked than other species of Zaireichthys.
It differs from Zaireichthys
conspicuus, Z.
kunenensis, Z.
lacustris and Z. maravensis in possessing
a narrow premaxillary tooth patch, less than 40% of
the mouth width; from Z. monomotapa by the
smaller number of rays in the dorsal fin, 4-5 soft
rays vs. 5-6), pectoral fins, 5-7 vs. 7-8, and caudal
fin, 9-13 vs. 14-16; from Z. kavangoensis
in colour pattern. Habitat: Found
in shallow water with a sandy bottom where it buries
itself. It feeds on small invertebrates, including
mayfly nymphs and caddis fly larvae. Colouration:
In life almost transparent, preserved usually very
pale yellow, with a few minute black spots scattered
irregularly over the body. A few specimens are darker,
but rarely show a definite pattern except for a series
of darker patches along the back, the first at the
base of the dorsal, and an irregular darker line mid-laterally.
The dark individuals can be readily distinguished
from the other members of the genus by the shape of
the melanophores, which are unusually large and rectangular
in shape. Etymology: Named for its
very pale colouration.
