Summer 2023 marks an important cultural milestone. That’s right, it has now been ten years since the release of SharkNado, which became a full-blown franchise with six movies, tens of millions in ad revenue and merchandise sales, real-world references in the floor of Congress, and near-universal awareness- all things that are otherwise unheard of for made-for-tv SyFy channel movies.

“It’s been incredible gift to be able to share something this fun and silly with so many people over all this time,” Thunder Levin, the writer of the SharkNado franchise, told me in an interview. “It’s been extraordinary how many different people seem to have embraced it. I get to interact with fans who come from all walks of life, I even get to argue with shark scientists!”
SharkNado has always had it’s thumb on the pulse of pop culture
The Bad Shark Movies genre is rich and storied, but none of the others have had anywhere near the cultural impact or legacy of SharkNado. I’d like to try and explain what made the SharkNado movies special, and explore what that means for cinema, for sharks, and for me.
Following a growing problem of mishandling of species of conservation concern, New York’s Department of Environmental Conservation is proposing some new shark fishing regulations. Here is the text of the letter I sent them supporting some of those proposed regulations, and proposing additional regulations.

Dear Commissioner Seggos, New York State Department of Environmental Conservation,
As a marine biologist with expertise in the conservation impacts of recreational fisheries on threatened shark species, I write in support of several proposed changes to New York State’s land-based shark fishing regulations. Additionally, while I am not a New York resident, I and my family have vacationed in your beautiful state every summer of my life. I learned to fish in New York from my grandfather, and those experiences contributed to my lifelong love of underwater life.
In 2011, the world’s first fishery for sharks was certified as sustainable by the Marine Stewardship Council*. The British Columbia spiny dogfish fishery made major news in fisheries management and ocean conservation world, where the possible existence of sustainable shark fisheries has been debated intensely. A few years later, the fishery voluntarily withdrew their certification, and never publicly said why.
I wanted to know what happened with this scientific mystery. So, with the help of Chuck Bangley and Catherine Macdonald and funding support from the Liber Ero Postdoctoral Fellowship program, I organized a research expedition to find out. The results of our expedition can be found in our new paper (LINK,) (OPEN ACCESS AUTHOR COPY) but in this blog post, I’d like to explain what we did, what we found, and why we think it’s important.
One year ago today, my book “Why Sharks Matter: A Deep Dive with the World’s Most Misunderstood Predator” was released. Science moves (relatively) rapidly and changes often, with new discoveries every day, and the conservation landscape is similar. This means that it is impossible for anything written about these topics at a discrete moment in time to remain accurate forever.
So, in the interest of accountability, in the interest of continuing to make my book useful for public education about shark science and conservation even as the science and policy landscape changes, and in the interest of keeping notes for myself for any future updated versions of the book, I have been keeping track of things that I wrote at the time that are no longer true, or weren’t quite right at the time. (Please note that some of these facts and figures were already out of date at the time the book was pubished, but that was well after the final text was turned in).
There were also a lot of fascinating scientific discoveries, which this post will round up for you. As always, this is not meant to be a “best” or “top” list, so if your science isn’t included here please do not send angry letters. This is just some cool stuff I learned this year thanks to my amazing colleagues, in no particular order. Whenever possible I’ll also provide links to further reading on the topic. I hope you enjoy!
Happy Shark Week (if you celebrate), and I’m so excited to share our newly published open access paper about our research on juvenile great hammerheads (Sphyrna mokarran) with you! (It’s been hard to keep this one to ourselves).
Great hammerheads are an iconic shark species which have undergone significant population declines globally. In 2019, they were assessed as Critically Endangered by the IUCN Red List, which reported overfishing as the greatest threat to their survival. Great hammerheads are known to make incredible long-range migrations and cross state and international boundaries, making them challenging to protect as adults. Little is known about where they are born or where they spend their early years of their life, although there have been scattered reports of juveniles from the Gulf of Mexico, the Florida Keys, and one report from Georgia.
Identifying habitats that are important to juvenile sharks matters because young sharks are often the most vulnerable individuals in a population, and their survival is vital to the future of their species. Many juvenile sharks spend time in “nursery areas”—places where they are less likely to be eaten by predators, or where food resources are abundant. They then expand their ranges as they age, covering more distance as they grow larger. Identifying nurseries has long been a conservation priority for managers and scientists. After several years of research, our team has collected the first scientific evidence of a nursery area for great hammerhead sharks on the Atlantic coast of the United States—within sight of the skyline of Miami, Florida.
There’s a three-part established test for an area to be identified as a shark nursery: 1) Juvenile sharks are more commonly encountered in that habitat than elsewhere; 2) they remain in the area for extended periods; and 3) The area is used repeatedly over years. Our results demonstrate that this area definitely meets two of these criteria, with preliminary evidence that it also meets the third. We’ve found the same habitat may be a nursery area for several other shark species too, including scalloped hammerheads, another Critically Endangered species!
You’ve probably seen in the media lately that there’s been a lot of coverage about whether sharks are being killed for SARS-CoV-2 vaccines. With an awesome undergraduate co-author, I’ve tried to gather some facts about what is happening (or might happen) and what it means. You can read a preprint of that work here, or read on for a short FAQ in plain English.
I wasn’t able to watch live this year, but I DVR-ed all 18 specials and watched them eventually! Here are my reviews, ratings, and thoughts. I did not watch the feature-length movie, which they claim is the first fictional entertainment content they’ve ever produced… causing me to stare in megalodon. Overall, this was not a strong year for science, facts, or diversity (of either sharks or shark researchers).
As a reminder, I grade on the following aspects of a show: is there actual science or natural history educational content / is there made up nonsense, are actual credentialed experts with relevant expertise featured or are they self-proclaimed “shark experts” who say wrong nonsense all the time, what species are featured (with bonus points for species we rarely or never see), and do they feature diverse experts or just the same white men (reminder: my field is more than 50% women)? It’s not a perfect rubric, but it’s better than this actual system for ranking shark news introduced this year in “sharks gone wild 2:”
Rankings appear in no particular order, if you care about the order the shows actually aired in please see this Discovery press release.
As the 2010’s come to an end, it’s a time to reflect on the often-problematic decade that was as we plan for a hopeful future. I am a sucker for year-in-review and decade-in-review listicles, and was devastated to learn that no one had yet written a decade-in-review listicle for sharks! Please enjoy my official, scientific list of the most important science, conservation, and pop culture sharks from the past decade.
I spent last week in Saba in the Dutch Caribbean with the
Dutch Elasmobranch Society, St. Maarten Nature Foundation, and the Saba
Conservation Foundation serving as a research assistant to an international
team of shark scientists participating in the Save Our Sharks Expedition 2019.
Expedition leaders Irene Kingma (left) and Dr. Paddy Walker (right) decked out in the official Save Our Sharks Expedition 2019 gear.
I first met Irene in 2014 when she invited me to give a keynote speech at the European Elasmobranch Association and have kept in touch with her through the years, mostly through Twitter. Irene has been working in shark conservation for 15 years, both in Europe and the Caribbean. She runs the Dutch Elasmobranch Society, which she founded together with Dr. Paddy Walker in 2010.
From 2015 to 2018 she worked as the Netherlands project
lead in the Save our Sharks project of the Dutch Caribbean Nature Alliance.
This project aimed to improve all aspects of shark protection in the Dutch
Caribbean through legislation, education, management, and science. The project has ended but the Save our Sharks
brand is still used for shark science and conservation work in the islands.
Irene and Dr. James Thorburn prepare the European Space Agency tiger shark satellite tags for deployment.
I sat down with Irene and asked her five questions:
Bucky: What is your role on this expedition?
Irene: I am the expedition leader. I’m in charge of making sure everyone knows where they have to be and what they need to do. I do this together with Dr. Walker, who took on the lead role after I left the expedition a few days before the official end. Paddy and I founded the Dutch Elasmobranch Society together in 2010, a science-based NGO dedicated to the management and protection of elasmobranchs in the Dutch Kingdom.
Bucky: How does the work you do contribute to global efforts to protect sharks?
Irene: My main job is helping policy makers to take the right decision on shark and fisheries management. For example, here in the Dutch Caribbean the Dutch Elasmobranch Society is the main adviser to the Dutch government on shark management and the measures needed to make the Yarari Shark Sanctuary a success. Together with local partners we wrote the proposals to get several sharks and ray species listed on the SPAW protocol, the only cross border legal protection instrument for the Caribbean region.
The expedition crew works up and tags a tiger shark.
Bucky: Why are sharks important to you?
Irene: My background is in ecology, so when I think of heathy oceans that should include all parts of the ecosystem. Sharks are a really good indicator of ecosystem wellbeing; to be able to sustain healthy, diverse shark and ray populations all elements of the system need be to in good shape. We need to protect everything from the corals and to whale sharks.
Bucky: How are we going to save the world’s sharks?
Irene: I am a firm believer in a holistic approach to management. Putting a species on a list like CITES, CMS, SPAW is an important first step. But you also need to have sensible implementation on the ground linked to effective control and enforcement. Plus, to ensure you get buy in by the people who are affected or have to carry out the protective work you need to communicate on what you want to achieve and why throughout the chain. And lastly all needs to be grounded in sound science to ensure what you do actually makes a difference in the water and for sharks. My mantra is we need to get the science we need to deliver the policy we want.
Bucky: What advice would you give to young scientists interested in a conservation careers?
Irene: Dream big! Here I am, a girl from Amsterdam who started out as a malacologist (snail specialist) leading an expedition to one of the most interesting places in the world to start up research projects which will help us protect sharks. Somebody pinch me! There’s no clear path that led me here, the only clear thread I see is that I tend not to take the safe option when it comes to career choices and I never gave up.
The Save Our Sharks Expedition 2019 runs from July 15-25.
