262: SOLEIDAE (SOLES)
Brownish, with small dark specks; sometimes with faint
dark or light bars on body. Attains 75 cm (4 kg). An important commercial species occurring in depths of 100 - 300 m
from northern Namibia to False Bay.
262.3 Austroglossus pectoralis
(Kaup, 1858)
PLATE 134
East coast sole
Ooskus-tongvis
Synaptura pectoralis Kaup , 1858: 96. Austroglossus pectoralis: Smith,
SFSA No. 325*; Nielsen, 1964: 131; Zoutendyk, 1974: 99; Hecht & Hecht,
1978: 210.
D 90-110; A 80-95; P 10; LL 150-170; vertebrae 58. Body depth 3.2-3.8
in SL.
Brownish , with a small dark spot at base of each scale;
right P blackish. Attains 58 cm. Known only from the Cape
to Natal; reported from Namibia (Lloris, 1982: 14), but this
record needs confirmation. Common in 10 - 120 m. Once
very abundant, the catches of this species have declined
noticeably in recent years; but the east coast sole is economically still the most important of the South African flatfishes.
