What emotion comes to your mind when you think about sharks? For many people around the world, that emotion is fear. But why is there so much fear surrounding the topic of sharks?
Unfortunately, sharks have a well-known negative image, instilled in us by movies and news stories that continue to terrify people. The media has introduced a sense of fear in us and because of this distorted framing; sharks have been branded as villains or “man-eaters,” and have been feared and hunted for centuries. But is the media really classifying the right group as villains?
Humans fear the unknown and assumed threats, but sharks fear the legitimate perils that they face everyday. I know what you are thinking, what should sharks be afraid of? Well, it’s us. Humans threaten sharks livelihood day in and day out. Sharks are some of the most biologically vulnerable creatures in the ocean because they grow slowly, mature late and produce few young.
We love Shark Week because it’s an entire week dedicated to one of the ocean’s coolest animals. With more than 500 species, there are a lot of reasons to love sharks! Here are some of our favorite shark facts.
I may be an ocean advocate, but I have been terrified of sharks for my entire life. So, on a recent trip to Hawaii, I decided to finally confront my fear and signed up for an ecotourism shark cage dive. When I gathered the courage to lower myself into the cage, I immediately came face to face with a large Galapagos shark and was shocked by the sense that an intelligent being was looking back.
Its movements were smooth and graceful as it glided tranquilly past; its gray, sleek body standing in beautiful contrast against the cobalt blue water as I began a tremendous discovery process that would change my view on sharks forever. After such a personal experience, I came home needing to learn more about these animals I’d feared for my entire life. What I discovered was that not only were sharks in trouble, but surprisingly that their disappearance would deliver a serious cost to us as well.

Many species of sharks and rays around the world are in trouble, and current events in Australia remind us of that. The government of Western Australia is presently implementing a controversial “shark cull” policy in response to recent highly publicized shark attacks near Western Australian beaches. The policy consists of deploying baited hooks about a mile off of various Western Australian beaches, aimed specifically at catching large sharks. Any shark larger than 10 feet is viewed as a threat to public safety and is to be “humanely” killed; the main targets of the cull are tiger sharks, bull sharks and great white sharks. Great white sharks are a protected species in Australia, and state authorities were given a special exemption from Australia’s Environment Protection and Biodiversity Conservation Act to be able to kill them. The shark cull is a pilot program. If it were to continue after the April 30 trial period ends, there would have to be a full environmental act assessment.

More than 70 species of shark occur in the Gulf of Mexico and along the U.S. Atlantic coast. Of those, we catch over a dozen large and small coastal species during the bottom longline population survey I’m participating in with the National Oceanic and Atmospheric Administration.
Here are five of the species we commonly spot:
Atlantic Sharpnose Shark This small shark is the most commonly caught species during our survey because it is ubiquitous in this region. In the right depths, it is not uncommon for us to catch around 50 of these small sharks per set of 100 hooks.
Population status: Due to their abundance in the western North Atlantic, their population status is not considered to be of great concern. Apart from humans, Atlantic sharpnose sharks also have other, larger sharks to fear as predators.

While most people out on the water are trying to avoid sharks, I’m on a boat that’s looking for them. We’re trying to find out which shark species are doing well and which ones are in trouble.
The answer: it’s complicated. But one important piece of evidence is the information collected on scientific surveys of population abundance, like the one I’m on right now.
It’s my third year as a volunteer on the science crew with the National Oceanic and Atmospheric Administration. I am currently on the NOAA ship OREGON II, a 170-foot research vessel with its home port in Pascagoula, Miss.
This is the first leg of the annual shark and red snapper bottom longline survey. The survey is conducted in the U.S. Gulf of Mexico from South Texas to the Florida Keys and along the East Coast up to Cape Hatteras, N.C. That’s a total of four legs lasting two weeks each.
