starspotted smoothhound shark pictures
Shark Picture Database
Names: Starspotted smoothhound.
Greyish brown body with many small white spots
above lateral line. Snout narrowly rounded with relatively close set nostrils.
First dorsal fin origin slightly anterior to free rear tip of pectoral fins.
Pectoral and pelvic fins relatively small.
Maximum recorded size: Male 96cm. Female 117cm.
Habitat: Mud and
in shallow bays on continental shelf.
Temperate/tropical Northwestern Pacific Ocean. From Siberia
southward to Vietnam including Korea, Japan and mainland China. Isolated records
from Kenya probably refer to an as yet undescribed species.
Diet: Mostly feeds on demersal invertebrates especially crustaceans.
without yolk sac placenta.
Recorded litter size 1-22, usually 2-6.
Population Status: Listed as Data Deficient by the
IUCN. However, the starspotted smoothhound sharks is caught in demersal longline
and trawl fisheries in the northwest Pacific and likely in other parts of its
range, and utilized for human consumption and fish oil (Compagno in prep). It is
of considerable importance to coastal fisheries and fishing pressure is high
within its known range. Once a common commercial species, that was heavily
exploited by coastal trawl fisheries and longliners throughout Taiwanese waters
to the point of almost complete disappearance. It is now difficult to find in
Taiwanese waters, with the exception of the waters off Chinsham and Kueishan
Island, northern Taiwan (Chen et al. 1996). With the expansion of coastal trawl
fisheries, Mustelus species have declined in the region, with a noted decline in
catch over the past 10-20 years. Species-specific management in this region is
problematic due to the multi-species nature of trawl-fisheries (Chen et al.
1996). A decline in catches has also been reported off Kyushu, Japan, and
investigation into the extent of these declines is required. Little specific
information is available on population trends and catches from elsewhere within
the species' range.
