Sharks have very tough skin that is generally covered in small, sharp scales varying in color depending on the species.
Sharks are frequently caught for their fins, which are used in shark-fin soup in certain cultures.
Shark's fins are highly prized in international trade but the shark carcass is not used and is thus usually discarded.

 Sandbar Shark - Chesapeake Bay Program
Requiem shark development can be either ovoviparous (in which the embryo develops within the protection of the mother's body and receives continuous nourishment from the yolk store) or viviparous (in which the young receives nourishment from a placenta and other maternal tissues, and the process results in the birth of live young).
Habitat and Life Cycle The sandbar shark, Carcharhinus plumbeus, true to its nickname, is commonly found over muddy or sandy bottoms in shallow coastal waters such as bays, estuaries, harbors, or the mouths of rivers, but it also swims in deeper waters (200 meters or more) as well as the intertidal zones.
Sandbar sharks are found in tropical to temperate waters worldwide, but in the western Atlantic they range from Massachusetts to Brazil and visit the Chesapeake Bay seasonally, from early spring to fall.

The Sandbar Shark is the commonest inshore shark in New Jersey waters.
Sandbar sharks are highly migratory, ranging in North America from New England to Florida and the Gulf of Mexico.
While sandbar sharks have large mouths, their teeth are relatively small and this makes it unlikely that they can attack anything larger than the prey on which they feed.

 Shark FAQs
Sharp declines in shark populations during recent decades in many areas of the world as a result of over-fishing and habitat loss are reducing the potential for shark-human interactions.
The most common shark species found in Virginia waters are sandbar sharks, smooth dogfish, Atlantic sharpnose sharks, and dusky sharks.
Sharks are susceptible to over-fishing because they grow slowly, reach sexual maturity at an advanced age (most of the larger species reach sexually maturity at 6-21 years), and produce only 8-10 pups every other year.

 South African White Shark Research Institute
The white shark is just an example, and if you look at all species, you find some which give birth to only one pup and some such as the Sandbar shark which only become sexually mature at about 25 years old.
Sharks unfortunately do not have the ability to adapt to these changes in their habitat, and therefore stocks are affected.
Most shark species utilise the inshore zone for nursery purposes which obviously indicates that these areas need to be stable, so when these nurseries are disrupted by say, a decline in prey, the young sharks may start broadening their predatory range.

 Length at Birth of the Sandbar Shark in Delaware Bay   (Site not responding. Last check: 2007-10-09)
Using 249 length measurements from the youngest sandbar sharks (cord-remains, open-fresh and partly healed umbilical scars), the mean (95% confidence interval) length at birth is 49.3 cm (19.4 in.) FL, with a range of 40 to 55 cm (16 to 22 in.) FL.
Springer (1960) stated the range in length at birth of sandbar sharks was 37 to 53 cm (15 to 21 in.) FL, and the length at birth in Florida (his reported southern limit of pupping grounds) was 52 cm (20 in.) FL.
A study of sandbar shark reproduction reported a mean embryo length of 49 cm (19 in.) FL (range 37 to 56 cm [15 to 22 in.] FL) in females during late May and early June, the pupping season in the Chesapeake Bight region (Colvocoresses and Musick 1989).

 The Shark Gallery - Sandbar Shark
A coastal shark, often in shallow waters associated with sandy or muddy flats, bays, estuaries and harbours (but not actually within rivers); also further offshore, particularly on banks, near islands, flat reefs and other topographic features in open waters.
Sandbars occur from the surfline down to 200m (caught at this depth, on the bottom, in Sicilian Channel trawls) and to 280m in other regions, but typically in waters less than 100m and frequently patrolling near the seabed.
These sharks predate upon demersal and benthic bony fish such as flounders, gurnards, groupers, morays and other eels, also mackerel, sardines, bonito, bullet tuna, jacks, mullets and other pelagic schooling fish; small sharks such as Squalus spp., batoids including Dasyatid rays; invertebrates such as squid, cuttlefish, octopi, bivalves, crabs and shrimps.
