In the ocean there are plenty of beautiful sea-creatures, but when a dorsal fin pops out of the water, panic erupts. This dorsal fin belongs to sharks. Sharks are all over the deep sea. From coral reefs to the deepest underwater caves, sharks dictate much of the life underwater. The Bull Shark, Tiger Shark, and the Great Hammerhead Shark are all amazing fish that have very important roles in their habitats.
To begin, Bull Sharks live in tropical waters and are one of the most aggressive and dangerous sharks in the world. One interesting fact about this shark is that they can live in freshwater. In fact, Bull sharks are found from the bottom of the Mississippi River, all the way to the river in Illinois. Bull Sharks are an average of ten feet long and eat just about any fish. Their diet also includes other sharks. To keep their pups safe from other sharks, much like the Bull Shark, they give birth in freshwater. This method of birth keeps the freshwater-intolerant sharks out.
In addition, Tiger Sharks have a lot of similarities to Bull Sharks. They are 16 feet long, weigh 1,000 pounds, and live in shallow tropical waters. One of the fascinating things about Tiger Sharks is their teeth. Each tooth is triangular and a whole row of teeth acts like a blade. Each straight row of teeth does its job with scary accuracy. One of the Tiger Shark’s favorite meals is the sea turtle. Although the sea turtle’s shell is very hard to break, the teeth of this animal manage to break it.
Lastly, the Great Hammerhead Shark. This unique shark has a flat hammer shaped head, hence the name. This phenomenon of a head is used to scan for fish and allows for agility in the water. At 20 feet long, the Great Hammerhead swims solo and can have up to 55 pups at a time. These sharks can be known to be aggressive, however Hammerhead Sharks are fairly calm.
In conclusion, sharks are amazing creatures, but they are dangerous. A huge thanks to Shark Academy for the information on these amazing sea creatures.
