Anal spines: 0; Anal soft rays: 19 - 22. This species
is distinguished with the following characters: short
head, nearly as broad as long; blunt snout, well-rounded
in lateral profile and dorsally; palatal tooth patches
posterior to premaxillary tooth band meet at midline;
rounded caudal-fin lobes, of near equal length, fin
not deeply forked; short and thick caudal peduncle;
underside of body (both head and belly) covered with
fine brown specks; anterior gill-rakers on first arch
10-13 (5 + 5); pectoral fin rays 9-12; fatty growth
along pectoral fin spines of breeding females not
present outside spawning season. The tail of the Black
Seacatfish is not as forked as other Seacatfishes
and is more round. The Black Seacatfish can easily
be confused with the White Seacatfish (G.
certain aspects are overlooked when identifying this
fish. Colouration: As it's name suggests,
the Black Seacatfish is a dark coloured fish and can
be any colour from a dark brown to almost black. The
colour underneath this fish is slightly lighter than
the colour on it's back, always dark. Often small
speckles can be seen on the underbelly of this fish.
The White Seacatfish is duller in appearance, a lighter
colour and can be dark brown, but never black in the
region. It has a light coloured or white underbelly
and often comes in big schools of fish. This species
is also frequently encountered in estuaries and shallower
water. Sexual differences: Dimorphism
present with posterior (humeral) process of cleithrum
obvious externally, fan-shaped in females, triangular
in males; smooth and shallow dorsomedian cranial depression
on exposed skull not reaching supraoccipital process.
Reproduction: Known to be paternal
mouthbrooders. Remarks: It is said
not to be in rivers estuaries and shallow water, however
we are starting to disprove this, and it is our goal
to prove this 100%.( Roocroft, Gareth: www.fishthesea.co.za)
