The name sand shark comes from their tendency to migrate toward shoreline habitats, and they are often seen swimming around the ocean floor in the surf zone; at times, they come very close to shore. They are often found in warm or temperate waters throughout the world's oceans, except the eastern

Vulnerable (VU) species are considered to be facing a high risk of extinction in the wild. The smalltooth sand tiger has been assessed as a vulnerable species.
