5.15 Etmopterus sentosus
Bass, D'Aubrey & Kistnasamy, 1973
Etmopterus sentosus Bass, D' Aubrey & Kistnasamy, 1973: 22, Figs. IS,
18a (southern Mozambique, Natal).
Dark grey above and below, markings indistinct - the
figure shows a faded specimen where the markings stand
out clearly. Two or 3 short rows of enlarged denticles on
each side below 1st dorsal. Only 4 known specimens: a 23
cm female from 454 m off the Kenya coast and 3 immature
specimens (2 male, 1 female, 24-27 cm) from deep water off
Natal and southern Mozambique.
5.16 Etmopterus sp.
Etmopterus granulosus (non Giinther) : Smith, SFSA No. SO· (in part).
?Etmopterus gracilispinis (non Krefft): Karrer, 1973: 199.
Head width at corners of mouth distinctly greater than length of snout in
front of mouth. Precaudal vertebrae 57-60 ; monospondylic vertebrae 4345. Southern African records of E. spinax are probably all referrable to
this species.
Dark brown above and below, no conspicuous flank
markings. Larger than most species of this genus, with

males immature at 44 cm, mature at 55 cm; attains 78 cm.
Trawled in deep water off southwestern Cape Province; 2
from northern Natal.
Genus Euprotomicroides Hulley & Penrith, 1966
No D spines. First D smaller than 2nd, its origin midway
between P & V. Short blunt snout. Long gill slits. One
species.

Hulley & Penrith, 1966
Euprotomicroides zantedeschia Hulley & Penrith, 1966: 222, Fig. 1 (off
Cape Town); Bass et aI., 1976: 50'.
Brown with black underparts. The 176 mm holotype, an
immature female trawled west of Cape Town, was
examined by Dr LJ. V. Compagno, who found that the supposed claspers are actually the enlarged lips of the cloaca.
An adult male of 41 cm has been reported from the southw.est Atlantic (Krefft, 1980: 7).
