Description:
Dorsal spines (total): 1. The head is more or less
flattened, the nostril nearly rounded, mouth inferior.
There are three pairs of barbels, 1 pair of maxillary
barbel and 2 pairs of mandibular barbels. Habitat:
Inhabits mainly brackish estuaries and lagoonsand
also occurs in freshwaters. Found on shallow muddy
bottoms and feeds on fish and shrimps. Two annual
cycles of slower growth occur during the dry seasons
(March and August to November). Life span is three
to four years. Sexually mature at 1.5 to 2 years of
age. Reproduction: Takes place from
November to April. Etymology:
The genus name Sciades: sciado-, canopy or
umbrella, probably referring to the occipital process,
described as a “distinct bony helmet”
(translation). The specific name proops:
pro-, before; ops, eye, referring to the eye
nearer to snout than to preopercle, compared to Bagrus
mesops (= S.
herzbergii), on which
eye is midway between snout and preopercle. Remarks:
The skull is sold throughout the world as a crucifix.
The underside of the skull covering has a bony structure
which can be seen when all the flesh and soft parts
are removed. It then looks like a crucifix or like
a painting of Christ crucified, and is surrounded
by a Weberian bone in form of a halo. The upper rough
part of the skull roof which is also visible on the
living fish, looks like a Monk with a cowl and hood
and his arms outstretched in prayer. Others see this
as a Roman soldier with armour on his chest and the
dorsal fin spine is the lance which he opened up Christs
side.
