The way that these animals got their name is largely due to the way that they hunt. Usually, these sharks will do their hunting at night, and they choose to do this near the edge of the shore. This means that they have to remain in the sand, which is how they got that part of their name. With regards to the tiger part, this is thought to be due to the fact that the animals have such a large appetite. An average meal can be large, and can include things like small fish and also things like lobsters and squid. Study of sand tigers has revealed that their favourite food is bony fish like mullets, eels, and sea basses.

It is not widely known for the animals to have large litters, and usually there are two pups born at once. These usually weigh around 13 pounds and are about three feet long. This is around the same size as a 4 year old child, so is already quite big as soon as it has been born. As soon as the shark is born, it is able to eat and swim on its own, although it will usually stay around its mother for a period of time, after it is born.The protection she gives, greatly increase the baby shark's chance of survival.
