Genus:
Scolidon
Species:
S. laticaudus
Description:
A small, stocky species, the spadenose shark
has a broad head with a distinctive, highly flattened, trowel-shaped snout. The eyes
and nares are small. The corners
of the mouth are well behind the eyes and have poorly developed furrows at the
corners. About 25–33 tooth rows are in the upper jaw and 24–34 tooth rows are
in the lower jaw; each tooth has a single slender, blade-like, oblique cusp
without serrations. The first dorsal fin is
positioned closer to the pelvic than
the pectoral fins, which are very short
and broad. The second dorsal fin is much smaller than the anal fin. No ridge occurs between the dorsal fins. The back is
bronze-gray in color, and the belly is white. The fins are plain, but may be
darker than the body. The maximum known length is 74 cm (29 in),
though unsubstantiated reports indicate individuals reaching 1.2 m
(3.9 feet).
