    The Spadenose Shark (Scoliodon laticaudus) is a small (to 91 cm total length) shark that occurs in the northern Indian Ocean from the Gulf of Oman to Myanmar. It is common in coastal and estuarine waters at depths of 10-75 m, but more typically less than 50 m and prefers muddy and sandy substrates and often occurs near large freshwater outflows. It is highly productive with annual large litters of 6–20 pups, early maturation at two years and a short generation length of 4.5 years. The species is caught mainly by trawl and gillnet in industrial and artisanal fisheries and is retained for human consumption. It is the dominant shark landed in Pakistan, northern India, and Bangladesh and fishing pressure is intenseacross most of its range. The high productivity of the species and short generation length likely provide it with resilience to fishing pressure, however, the intense and ongoing fishing pressure on this species is a cause for concern. It is suspected that the Spadenose Shark has undergone a population reduction of 20–29% over the past three generation lengths (14 years) and is close to reaching the population reduction threshold due to levels of exploitation, and it is assessed as Near Threatened (nearly meeting Vulnerable A2d).
