5 Different Types of Sharks and What Makes Each So Special

 

Dating to over 300 million years ago, sharks are a prehistoric creature that are still a critical part of marine ecosystems today. While they have gotten a bad rap over time, for the most part, they are not threatening to humans. In reality, we are a much greater threat to them. 


Human interactions with sharks have led to the deaths of approximately 100 million sharks each year, which has caused a dramatic decline in many shark populations. Caught as bycatch, captured for finning, and affected by commercial boat noise, pollution, and climate change, sharks are constantly under attack. It’s up to us to make a change and to show that we care.


We can’t list all the types of sharks here, but we can share a little about some of them and what makes them so special.

  1. Nurse Shark

Bottom dwelling nurse sharks are non-aggressive and the slowest sharks in the sea, making them a beloved variety that are typically harmless to humans. They feed primarily on sea urchins, fish, shrimp, squid, and conchs and rest frequently on the ocean floor. They can be social, however, they can’t make verbal sounds (nor can any shark). Instead, they communicate through movement, sensing the vibrations of other nurse sharks to communicate.

  1. Tiger Shark 

There are tigers in both the jungle and the sea. The tiger shark was named as such because it has tiger-like stripes covering its body while it’s young. While the stripes eventually fade, this is still a large predatory shark that can reach around 18 feet. They primarily reside in tropical and subtropical areas and eat everything -- literally everything! They are like a garbage disposal at sea, scavenging on dead animals, fish, and sea creatures. 

  1. Great White Shark

Perhaps the most notorious shark because of the movie Jaws, the Great White is the largest predatory shark in the ocean. At full size, they measure around twenty feet and weigh over 6,000 pounds. They are warm blooded, unlike many sharks, which allows them to live in cold and warm water. They feed primarily on sea lions and seals and most terrifyingly, can detect a drop of blood from up to three miles away. Fortunately, human attacks by Great Whites are very rare. 

  1. Hammerhead Shark

Hammerheads are one of the coolest looking sharks in the sea. With a uniquely shaped head that resembles a hammer, they can actually see in 360 degrees. There are many different species of hammerheads worldwide, including the mallethead, winghead, great hammerhead, scalloped hammerhead, and scoophead sharks. They use their heads to trap their prey, preferably stingrays.

  1. Saw Shark

With a long, saw-like snout, saw sharks also have a really unique look. There are nine species of this type of shark, all with a characteristic snout which is ridged with sharp teeth that they use to strike prey. Saw sharks are relatively small, measuring up to around 4.5 feet long at full size. While they look a bit menacing, they are not harmful to humans.
