When you think of the word “shark,” you probably immediately think of a uniform look that belongs to the great white shark. However, there are many types of sharks in the ocean, with different body lengths and weights, and different physical characteristics. For example, the tiger shark gets its name from the vertical stripes on the sides of its body, which resemble a tiger. These vertical bars are usually evident in their juvenile stages and usually fade away over time or as tiger sharks become adults.
The tiger shark is the second largest predatory shark in the world after the great white, reaching a maximum length of 18 feet and a maximum weight of approximately one ton.
As the top of the food chain, tiger sharks, like most shark species, are very aggressive and will eat anything small enough for them to catch. As slow-moving fish, they favor easy prey by ambushing, stalking and then grabbing prey as a major hunting stunt. That being said, it is clear that these fish possess sharp and strong teeth that allow them to catch and kill their prey with little effort.

Tiger sharks have 48 identical teeth, lined up in the upper and lower jaws. Unlike mammalian predators, which have different sets of teeth, sharks’ teeth have the same appearance.
Most sharks that chase swimming prey have an upper jaw used to pierce the flesh of the prey, and a lower jaw used to grab the prey and hold it in place. Unlike these types of sharks, the 24 upper and lower teeth in the upper and lower jaws are the same for all tiger sharks. This allows the tiger shark to cut and grab prey with its two jaws. Cutting and sawing areas can be found on tiger shark teeth.

What do tiger shark teeth look like?
The tiger shark’s teeth are distinctive in appearance, short and broad, and appear to be strong. Serrations adorn the sharp blades that help tiger sharks pierce clams and shells.
Tiger shark teeth are easily identified by their sloping tips and sharp serrations. Even turtle shells are no match for their sharp teeth, which can slice through bones, meat, and even the shells of other animals. Like most shark species, tiger sharks shed and replenish these teeth continuously throughout their lives.
Tiger sharks have larger mouths than other members of the true shark family. Elongated serrations and sharp edges protrude from the side of each tooth, shaped like the others. Their teeth can also be used as saws, as they have a sawtooth-like area in their mouths.
How strong is a tiger shark’s bite?

What distinguishes the tiger shark from most shark species is its teeth and jaws. Tiger sharks have a bite pressure of 6,000 pounds per square centimeter or more. The tiger shark tooth also has a special section, which is a flatter rear tooth assembly that protects the saw’s wide cutting area from the shark’s massive bite pressure.
How do tiger shark teeth work?
The tiger shark’s identical set of teeth serves two functions: to grab and hold struggling prey, and to cut and tear thick skin of any kind, making their food menu more extensive.
A tiger shark’s jaw will open to reveal its teeth, with the tips pointing in opposite directions. The teeth on the left and right halves of the jaw also look like mirror reflections of each other. In addition to being able to pierce the toughest skin, tiger shark teeth aid in the fish’s ability to grab prey as it fights for life.
Also, unlike other sharks, tiger sharks have square rather than round jaws. In the middle of the tiger shark’s snout, the cartilage of the lower jaw meets at a near-perfect angle, giving this shark its distinctive appearance.
As sharks are known to prey on sea turtles frequently, their tooth structure needs to be strong and sharp enough to slice through the creatures’ shells.
How Long Are Tiger Shark Teeth?

Tiger shark teeth are usually around 1 inch in length, but can sometimes grow as long as 1.5 to 2 inches. The short, notched teeth of tiger sharks set them apart from other shark species and are actually one of the tiger shark’s most defining characteristics. Tiger sharks have sharp, serrated teeth on their shoulders that also help them crush clams and even the shells of many sea turtles.
Tiger sharks can average 10-14 feet in length and weigh 850-1,400 pounds. The largest female tiger shark ever recorded weighed 1,780 pounds, but tiger sharks that have not been “officially” weighed are believed to have grown to even larger sizes! Great white sharks can grow to be several feet longer than tiger sharks, and the largest great white shark ever recorded is estimated to have weighed 5,000 pounds!
Do Tiger Sharks Bite?
Although sharks rarely attack humans, tiger sharks are among the most dangerous and have been linked to many deaths from tiger shark bites. It is not uncommon for them to venture into shallow waters such as harbors and canals, where they may come into contact with humans.
When it comes to attacking humans, there are no predators more powerful than the great white shark, but tiger sharks have even made a name for themselves as cannibals, and they are second only to these giant sea creatures when it comes to attacking humans. However, keep in mind that while shark attacks occur from time to time, in any given year, sharks kill less than 1,000 of the people snakes kill. That said, you shouldn’t lose any sleep over a shark attack.
I am broadly interested in how human activities influence the ability of wildlife to persist in the modified environments that we create.
Specifically, my research investigates how the configuration and composition of landscapes influence the movement and population dynamics of forest birds. Both natural and human-derived fragmenting of habitat can influence where birds settle, how they access the resources they need to survive and reproduce, and these factors in turn affect population demographics. Most recently, I have been studying the ability of individuals to move through and utilize forested areas which have been modified through timber harvest as they seek out resources for the breeding and postfledging phases. As well I am working in collaboration with Parks Canada scientists to examine in the influence of high density moose populations on forest bird communities in Gros Morne National Park. Many of my projects are conducted in collaboration or consultation with representatives of industry and government agencies, seeking to improve the management and sustainability of natural resource extraction.
