Sand tigers, with their large build and mouthful of protruding spike-like teeth, are the image that most people picture when it comes to sharks. 

This species of shark can grow to be about 10 feet in length and 350 pounds! Sand tiger sharks are widely distributed in all warm seas except the eastern Pacific.

Recent Discovery:
Sand tiger sharks embryos eat each other in the womb until only two remain. This is thought to be a struggle for paternity - basically babies from different fathers are competing.
This was discovered by Demian Chapman in 2013.

The Sand Tiger Shark

The Sand Tiger Shark is a species of shark that lives in coastal waters worldwide. It gets its name because it resides so close to the sandy beaches of North America.

The Sand Tiger hunts close to the shore and has been observed to hunt schools of fish within their own groups. They are relatively a slow-moving shark and unlike other sharks, the sand tiger can gulp air from the surface.

On the International Union for Conservation of Nature Red List, they are listed as threatened. They are listed as endangered under Queensland’s Nature Conservation Act.

It is illegal to harvest any part of the sand tiger on the United State’s Atlantic Coast. Sand tigers are often caught in fishing nets where they are either strangled or taken by fishermen. Shark liver oil is a popular ingredient in lipstick and their fins are traded in Japan.

Sand tiger sharks (Carcharias taurus) have a deceivingly ferocious look. They are large-bodied and display a mouthful of sharp teeth that protrude in all directions, even when the mouth is shut. Despite this, they are a docile, non-aggressive species, known to attack humans only when bothered first. They are brownish-gray with rust-colored spots on top and white underneath. They have a flattened, cone-shaped snout and a distinctive, oblong tail with a notched, upper lobe that is significantly longer than the lobe below. Individuals range in size from 6.5 to 10.5 feet (2 to 3.2 meters) in length. They have a tendency toward shoreline habitats, and they are often seen trolling the ocean floor in the surf zone, very close to shore. They are found in warm or temperate waters throughout the world’s oceans, except the eastern Pacific. Sand tigers are the only shark known to come to the surface and gulp air. They store the air in their stomachs, which allows them to float motionless in the water, seeking prey. They are voracious predators, feeding at night and generally staying close to the bottom. Their staple is small fish, but they will eat crustaceans and squid as well. They occasionally hunt in groups, and have even been known to attack full fishing nets.

About your latest post about sharks. Is it true that all the baby sharks inside their momma fight for survival and in the end only the strongest one that killed all others is born? Or maybe it's true only for some sharks? I think I heard it about Great Whites but I don't really remember

I believe that is only true for sand tiger sharks. They’re pretty well known for it. Here’s a Smithsonian article on it for more reading.
