5: SQUALIDAE (DOGFISHES)
5.17 Euprotomicroides zantedeschia: 18 em female (off Cape Town); d =denticle.
Genus Euprotomicrus Gill, 1864
Body cylindrical, tapering to a narrow caudal peduncle.
No D spines; minute photophores scattered over ventral
surface of head and body. Monotypic; Hubbs et al. (1967)
have published a fine paper on the taxonomy, anatomy and
biology of this species.
5.18 Euprotomicrus bispinatus
(Quoy & Gaimard, 1824)
Scymnus bispinatus Quoy & Gaimard, 1824: 197, PI. 44, Figs. I, 2
(Mauritius). Euprotomicrus bispinatus: Hubbs et aI., 1967; Bass et aI.,
1976: 47*.
Head and body black, fins with prominent white (transparent in life) areas as shown in figure. A dwarf species,
with males maturing at 17 cm, females at 22-24 cm; attains
27 cm. Bathypelagic, making regular nocturnal migrations
to the surface (where it is easily taken with a dip-net or
bucket); during daylight hours it inhabits depth in excess of
300 m. A shark of the open seas, it has been found in all
