The exact number of sand tiger sharks left in the world is difficult to determine due to their wide distribution and the challenges in conducting comprehensive population surveys. However, sand tiger sharks are considered vulnerable by the International Union for Conservation of Nature (IUCN).
Sand tiger sharks face several threats, including overfishing, bycatch, and habitat degradation. These factors have contributed to a decline in their population. Conservation efforts are ongoing to protect this species, including regulations on fishing and the establishment of marine protected areas.
While precise numbers are not available, it is clear that sand tiger sharks are at risk, and continued conservation efforts are essential to ensure their survival.
