Several different fish species are called 
Sand shark in their  native regions. In the USA and UK, the name Sand shark refers to , a  species more commonly known as Sand tiger shark. In the UK and around  Mauritius, the Gigant guitarfish (
Rhynchobatus  djiddensis) is known as Sand shark. The Yellow guitarfish (
Rhinobatos schlegelii) is also called  Sand shark in these waters. Around Bermuda,  the Nurse shark (
Ginglymostoma cirratum)  is sometimes instead called Sand shark. In New Zeeland, it is the Smalltooth  sand tiger (
Odontaspis ferox) that is  commonly known as the Sand shark. The Bigeye sand tiger (
Odontaspis noronhai) is yet another species that often gets its name shortened down to  simply Sand shark in everyday language. 
            
      
                  
Carcharias  Taurus 
                  This sand shark is commonly referred to as 
Sand  tiger shark and is found in warm-temperate and tropical waters in the Atlantic  Ocean, Indo-West Pacific Ocean and the Mediterranean Sea. It has never  been found in the Central Pacific or Eastern Pacific Oceans. This fish  prefers to stay in coastal regions. This sand shark is widespread, but  regional populations tend to stay isolated and are not believed to  breed with each other. 
The largest measured Carcharias Taurus was 320 cm long and the  largest recorded weight is 158.8 kg. The body coloration is brownish to  grey with dark spots. The dark markings are more noticeable in young  Sand sharks and tend to fade as the animal matures. Belly and fins are  pale. Just like many other sharks, this Sand shark has a short, pointed  snout and small protruding teeth that are shaped like spikes. The eyes  are small. The caudal fin has a distinct subterminal notch and the  ventral lobe is short. The dorsal and anal fins are equal-sized and the  first dorsal fin is located closer to the pelvic fin than to the  pectoral fins. 
This Sand shark has one of the lowest reproductive rates of all the  researched elasmobranch species, which make it very vulnerable to  environmental treats. It is included in the IUCN Red List of Threatened  Species. A female Carcharias Taurus will not give birth to more than  one or two young every second year. Some of the largest treats to the  survival of this Sand shark are commercial fishing, beach meshing and  spear fishing. 
Ginglymostoma  cirratum

Nurse shark) can be found here: 
Nurse shark 
Odontaspis  ferox 
 This fish is commonly known as 
Sand shark,  Sandtiger shark, Smalltooth sand tiger shark, Ragged-tooth shark and Herbsts nurse shark.  This Sand shark is found from 50° N to 49° S and from 121° W to 177° W.  It prefers deep waters and its dept range is 10-530 meters. It occurs  in many parts of the world, including the Eastern and Western Atlantic,  the Mediterranean, the Indo-West Pacific and the waters near Australia,  New Zealand and southern Japan. In the Central Pacific it has been  sighted off Hawaii, and in the Eastern Pacific you can encounter this  Sand shark off the coast of southern California (USA) and Baja  California (Mexico). It is most likely also found in the Western  Central Pacific. 
The largest Odontaspis feroxever reported was 367  centimeters, and the heaviest specimen weighed 289 kilograms. The body  coloration is grey and the belly is pale. Some specimens have their  sides decorated with red spots. The snout of this Sand shark is short  and pointed. The eyes are small and the teeth are small and shaped like  spikes. The dorsal and anal fins are of equal size and quite small. You  will find the first dorsal fin nearer to the pectoral fin than to the  pelvic fin. 
This Sand shark is included in the IUCN Red List of Threatened  Species. It has a minimum population doubling time of over 14 years,  which makes this species highly vulnerable. It is often caught  (sometimes incidentally) by fishermen. The flesh is eaten by humans and  the liver is a rich source of squalene. 
Odontaspis  noronhai
 This Sand shark is commonly known as Bigeye sand tiger. It inhabits  deep waters in a region that stretches from 31° N to 34° S and 163° W  to 27° W. Its dept range is a remarkable 600 – 1000 m. In the Atlantic  it has been found off the coasts of Brazil and Madeira. In the Eastern  Central Pacific this Sand shark lives off Hawaii. Some unverified  reports also claim that this shark has been spotted near the  Seychelles. 
The largest captured male Odontaspis noronhai was 360 centimeters  long, while the biggest female was 326 centimeters. This Sand shark has  a conical and bulging snout, with a rounded tip. The eyes are big. The  body has a chocolate brown coloration and all the fins have dark edges,  with the exception of the pectoral fins. 
This Sand shark is included in the IUCN Red List of Threatened  Species, but since it inhabits such great depths the scientific  community knows very little about its population status. It has a  minimum population time that exceeds 14 years. Much more research is  necessary to determine the true status of this Sand shark. 
Rhynchobatus  djiddensis
 This Sand shark is more commonly known as 
Giant  guitarfish or Whitespot giant guitarfish.  It is found in the Western Indian Ocean. The population is restricted  to the Red Sea and the warm tropical waters of the western Indian Ocean  down to South Africa. It is sometimes mixed up with other closely  related species that live in the north and eastern regions of the  Indian Ocean and in the western Pacific. This Sand shark likes to stay  around reefs and has a depth range of 2-50 meters. It is commonly found  inshore and in shallow estuaries and feeds chiefly on small fishes,  squids, lobsters, crabs and bivalves. 
The largest recorded Rhynchobatus djiddensis was 310 centimeters  long and the heaviest specimen weighed 227 kilograms. The body has big  dark eyespots on the pectoral bases and you can see a characteristic  black cross between the eyes. The body coloration is olive-green and  the upper body is decorated with rows of tiny white dots. The belly is  pale. This Sand shark has a pointed snout and a short lower caudal  lobe. The mouth is small and equipped with flattened teeth (they  actually look quite similar to a pavement). 
This Sand shark is included in the IUCN Red List of Threatened  Species. The flesh of the Rhynchobatus djiddensis is delicious and the  fins are highly sought after in Asian fish markets. This makes this  Sand shark one of the most valuable fish species, and it is therefore  important for fisheries. It is also a popular gamefish. Many  Rhynchobatus djiddensis are today kept in public aquariums. This sand  shark is sensitive to over fishing and other environmental treats since  its minimum population doubling time is from 4.5 and up to 14 years. 
Rhinobatos  schlegelii
 The 
Yellow guitarfish is similar to the Whitespot giant  guitarfish, but will only grow up to 1 meter. Its depth range is 0-200  meters and it spends most of its time close to the coast, preferably on  sandy or muddy bottoms. You can find this Sand shark in subtropical  regions in the Western Pacific; from Korea to the Philippines. Small  benthic animals make up most of the diet for this Sand shark. This is  one of the most appreciated food fishes in the family 
Rhinobatidae (Guitarfishes) and it is therefore important for  fisheries in the region. The fins are served raw with seasonings. They  can also be eaten boiled, and dried fins are used to prepare shark-fin  soup. This Sand shark is not included in the IUCN Red List of  Threatened Species. Its minimum population doubling time is 4.5 to 14  years.
