sand tiger shark teeth.super sharp.about tiger sharks:

list of facts about tiger sharks wouldn’t be complete without a statistic regarding their size. Tiger sharks are actually the fourth largest shark out there in the world! They average around 3-4.25 meters in length and can weigh anywhere between 385-650 kilograms. If you aren’t too familiar with the metric system, 650 kilograms comes out to about 1,500 pounds! That’s one bug fish! It makes sense too, since these fish are in fact, apex predators of the sea!

We will continue our facts about tiger sharks by going over something that is related to their size; their appetite! Tiger sharks are also famous for their diverse selection of food that they will ingest. In fact, their nickname amongst their peers is the “wastebasket of the sea.” With a nickname like that, it must mean that no piece of food is deemed unappealing to a tiger shark.

These scavengers will eat stingrays, dolphins, seals, squids, turtles, crabs, mammals, sea birds, and even other sharks if necessary. Their selection of food doesn’t stop there. Tiger sharks will also consume man-made objects and various pieces of human garbage, including bottles, pieces of boat, and even weathered tires. This wide range of food choices is by far the most abundant compared to other shark species out there in the world.

more facts about  tiger shark:

The last of our facts about tiger sharks deals with their habitat. Tiger sharks are known to inhabit coastal and pelagic (open sea) waters that can be 350 meters deep. They are known to prefer murky waters within the coastal areas, but will frequent coral reefs and lagoons as well. On top of all of this, tiger sharks are also known to migrate seasonally, moving to temperate waters during the summer, and returning to tropical waters during the winter months

the crow shark teeth.looking wide.and i dont know any facts so ya.....

the otodus shark teeth.Its fossilized teeth aside, Ototodus' greatest claim to fame is that it seems to have been directly ancestral to Megalodon, the 50-foot-long, 50-ton predatory behemoth that ruled the world's oceans right until the cusp of the modern era. (This is not to diminish Otodus' own place in the record books; this prehistoric shark was at least one and one-half times as big as the biggest Great White Sharks alive today.) Paleontologists have established this evolutionary link by examining the similarities between these two sharks' teeth; specifically, the teeth of Otodus show early hints of the flesh-ripping serrations that would later characterize the teeth of Megalodon.

and that is all
