Midwest shark scientist begins groundbreaking research on secret lives of sharks

By: Nick Whitney, Senior Research Scientist

We announced last fall, the arrival of Dr. Nick Whitney at Newport Aquarium. Read more here: Newport Aquarium announced Renowned Shark Scientist, Nick Whitney, joined the Newport Aquarium team.

From the time I was a young kid growing up in Michigan I knew exactly what I wanted to be when I grew up: a garbage man. What could be better than riding around on the back of a truck all day, wearing whatever you want, and playing your music at full blast?

As I grew up I tried various other jobs: I umpired softball but was always getting screamed at by half the people (the half that knew the rules). I worked construction for a while but accidentally shot my boss in the hand with a nail gun (he handled it well). I worked in an aquarium store but got fired for missing too much work (spring break trip to Florida).

With all of these career failures during high school, college seemed like a logical choice for me. I was intrigued by the work of Dr. Jeff Carrier, a professor at nearby Albion College (Albion, MI), who was studying sharks in the Florida Keys. A shark scientist in the Midwest? What a concept!

I had been fascinated with sharks all my life, and my experience in the aquarium industry (including breeding some endangered species in a series of tanks in my bedroom), made me the closest thing to a marine biology student that this professor could find at a small liberal arts college in Michigan.

Jeff took the time to meet with me and eventually invited me to come to Albion and help him with his shark research. It took me about half a second to accept this invitation, and as an undergraduate I spent three summers capturing, tagging, and tracking nurse sharks on their mating grounds in the Florida Keys. I had the time of my life – no one screamed at me, there were no nail guns, and my boss was the one sending me on spring break trips to Florida.

I learned how to handle myself on the water and how to handle sharks without getting bitten (most of the time). I also learned science skills that made me a good candidate for graduate school at the University of Hawaii.

Working in Hawaii for 8 years and Florida for another 7 after that put me on the front lines of shark research, and in the process I started learning how to use a new type of tag called an accelerometer.

These tags use the same sensors found in Fitbits, smartphones, and video game controllers to reveal fine-scale details about the secret lives of sharks. I’ll talk more about these cool tools/toys in an upcoming post.

It’s now 2017 and you can do whatever you want from almost anywhere! Take it from a shark scientist working for an organization in Boston, MA (New England Aquarium) living in Cincinnati, OH, working in Newport, KY, who still does much of his fieldwork in Florida. It sounds complicated, and it took some time to set up, but so far it’s fantastic.

My research now focuses largely on what happens to sharks after they are caught and released by fishermen. Our tags allow us to determine whether the sharks live or die, and how long it takes them to recover and start swimming normally again.

I’m also involved with exciting research on the behavior of sea turtles and other species, and all of my work involves a heavy logistical component. By that I mean we often have to design and build new tag packages for different projects. So I spend a lot of time brainstorming ideas on how we can combine different tags, how we can attach them to animals, and how we can get them back.

This is one of the things I am excited to work on with my new colleagues at Newport Aquarium. I now have easy access to a number of different sharks and rays (and other species) just 20 minutes from my house. We will be taking advantage of this in the coming months by testing a number of different tag packages and attachment styles, some of which you may see on animals when you visit the aquarium.

The whole goal is to figure out the best way of attaching these tags so that they will stay on the animals without inhibiting them. This takes a lot of trial and error, so don’t be surprised if most of the tags you see are in various stages of falling off the shark. That means we’re learning!

I’ll also be helping the biologists at Newport Aquarium to formalize and publicize some of the research they have already been doing over the past several years. This includes some groundbreaking work in breeding and rearing shark rays that reminds me a lot of my work with mating nurse sharks in the Keys. So exciting!

Now my kids get to come to Newport Aquarium almost weekly and are blown away by the place. They try very hard not to admit that their uncool dad has a cool job, but once they start walking through the exhibits they go bonkers. My 2 year old wakes up in the middle of the night and says, “Go see Dory?”

They may grow up to be garbage men, or umpires, or construction workers, or most likely some career that doesn’t even exist today. But if they decide to be shark scientists, they have every reason to believe they can do that from here, or anywhere in the country.

 

 

 

Celebrating Shark Week: Atlantic Ocean Sharks at Newport Aquarium

Sand Tiger Shark

Sand tigers, sandbars and nurse sharks, which frequent the eastern and southeastern coast of the United States, are some of the most recognized sharks at Newport Aquarium. These sharks have drastically different characteristics that make them so well known. Contrary to popular public opinion, these sharks are quite docile and would only attack humans when provoked.

Best known for their curled and hinged mouths, nurse sharks can often be seen on the warm waters of the seabed where they use their strong jaws to crush and eat shellfish and even coral. They prefer to feast on fish, shrimp and squid that frequent that given body of water.

Sandbar shark

The sandbar shark is the best identified for its high first dorsal fin and inter dorsal ridge. Like the nurse shark, sandbar sharks rarely make an appearance above water. They frequent harbors, bays and the mouths of rivers, preferring naturally protected salt waters with smooth sandy bottoms where it feeds on bottom dwelling fish.

Sand tiger sharks are identified by their long jagged teeth that protrude from their open or closed mouths; giving them the reputation as ferocious killers. Despite their looks, they are docile, non-aggressive and normally only attack humans when provoked. Their food preference is small fish, squid and crustaceans. They are the only sharks known to come to the surface for air. They store the air in their stomachs, which allows them to float motionlessly in the water to seek prey while staying close to the bottom of the body of water.
