Sharks
Taking a Bite of the Blue Economy
As Shark Week draws to a close, take a minute to check out how sharks are boosting ecotourism in Mexico. Ashley MickensI recently graduated with a degree in Environmental Earth Science and Sustainability from Miami University of Ohio, and I’m currently working as a marine mammal observer in the Atlantic. While my undergraduate research focused […]
Shark Sleuthing: How scientists can identify which species of sharks attack
Though shark attacks are uncommon, it is in humanity’s best interest to learn all we can about the sharks responsible. But how can we do that if the shark was not clearly visible by victims or witnesses? Scientists have developed ways to identify shark perpetrators by examining the DNA left behind in bite wounds. Francesca […]
A mysterious, 19 million years ago mass extinction of sharks
Citation: Sibert, E. C., & Rubin, L. D. (2021). An early Miocene extinction in pelagic sharks. Science, 372(6546), 1105-1107. 10.1126/science.aaz3549 Fossilized remains preserved at the bottom of the ocean have revealed that around 70% of sharks suddenly went extinct about 19 million years ago. The reason why remains unclear, but this enigmatic extinction event provides a warning […]
Sleeper Sharks: From the jaws of defeat
There are many stories of species close to extinction. Sometimes, species can go locally extinct, disappearing from a particular area. Once this happens, is it possible for species to return to that area? What can humans do to help these species come back? A success story from the Galapagos shark may hold some answers. Francesca […]
One Fish, Two Fish, Climate Change, Who Lives?
There is variation within species, and this variation can lead to some individuals surviving better in the face of environmental change. But it is difficult to predict how animals will respond to an environment that is changing faster than they can evolve. Luckily, some scientists found a clever way to study how individuals might respond […]
Shark Smarts: Can associative learning change shark behavior?
We all know that sharks are excellent hunters, but can the instinctual predatory mind of one of the ocean’s apex predators be influenced by the fishing actions of humans? Can sharks learn to feed differently based on human presence? Francesca GiammonaI am a PhD candidate at Wake Forest University, and I received a B.S. in […]
From Table to Tour Boat: How Our Perception of Large Marine Animals Has Changed Over Time
Whether they elicit feelings of awe, admiration, or fear, there’s just something fascinating about large animals. In the Western world, large marine animals (or marine megafauna as scientists call them) have experienced a polarizing shift in how human societies view them over the last 50-100 years. In their recent article, published in PLoS ONE this […]
A game of shark and ray: Rays act differently when sharks are around
As our oceans change, we don’t really know what the current decline of sharks means for stingrays, or for the coral reefs where they both live. Scientists at James Cook University and the Australian Institute of Marine Science want to find out. Kristin HuizengaI am a PhD student studying Biological Oceanography at the University of […]
Sinking Alligator Carcasses into the Deep Ocean to See What Eats Them
The Deep Unknown The deep ocean is an alien world. Life here must contend with crushing pressures, near-freezing temperatures, and a complete absence of light. At more than a thousand feet deep, it’s also the least explored and least understood ecosystem on Earth. That’s a problem, because the deep makes up about 95% of […]

Birds of a feather are eaten together: Young tiger sharks take a bite out of migrating songbirds
Drymon, J. M., K. Feldheim, A. M. V. Fournier, E. A. Seubert, A. E. Jefferson, A. M. Kroetz, and S. P. Powers. 2019. Tiger sharks eat songbirds: scavenging a windfall of nutrients from the sky. Ecology 00(00):e02728. 10.1002/ecy.2728 Tiger sharks are well known to be opportunistic feeders, and that description isn’t limited to just live […]
Does ocean circulation provide prey for a top ocean predator?
Ocean circulation patterns are generally thought to move water from one area to another in the world’s oceans. One example of this includes eddies, swirling water masses that spin off from major ocean currents such as the Gulf Stream off the coast of the eastern U.S. Some of these eddies can bring more productive waters […]

Reconnecting with Sharks
Sharks: an animal we love to fear. Sharks are an essential part of the environment; unfortunately, these animals are facing the most danger in the entirety of their 450 million year old existence. What can we do to protect these amazing elasmobranchs? The first step is reconnecting with sharks. Rishya NarayananRishya is a multimedia science […]

Killing Jaws: Tackling the Idea of the Bloodthirsty Predator
Even though shark attacks are rare, fear of sharks has led people to support laws that kill sharks en masse. A new study shows that at the root of our fear of sharks is the belief that they intend to hurt us. By thinking about how we talk about shark intentionality in educational settings and […]
