Tracking the Bay’s Rays: Cownose ray migration along the Atlantic coast

If you’ve ever tickled the back of a stingray in an aquarium’s touch tank, you’ve likely introduced yourself to a cownose ray. Despite their popularity in aquaria throughout the U.S., little is known about the movements of these fish in the wild. Grace CasselberryI am currently a Marine Science and Technology Doctoral student at the […]

In the hot seat: Hot spots for pelagic shark movement reflect hot spots for commercial longline fisheries in the North Atlantic.

Check out the latest from Matt Larsen about shark habitat around the globe, and how these areas overlap with fishing hotspots! Matthew LarsenI am a second year master’s student at Coastal Carolina University in the Abel Lab. My interests focus on the ecology and life history of large marine megafauna with a central focus on […]

Shark Intelligence: Who needs a degree when you’re schoolin’ life?

People often associate intelligence with mammals because humans are mammals and we like to think of ourselves as being pretty smart. The movie Deep Blue Sea toys with the concept of genetically modified hyper-intelligent sharks running loose in a research facility. While this Sci-Fi thriller is a sensational over-exaggeration, it does pose an interesting question: […]

Saving Sawfish: Adventures in the Everglades

A few months ago, I wrote about sawfish research in Papua New Guinea, but if you live in the U.S. you can find sawfish much closer to home. The smalltooth sawfish (Pristis pectinata) once roamed throughout the Gulf of Mexico and along the East Coast, but now calls South Florida, particularly Everglades National Park, home. […]

The shark and the side salad

Everyone knows all sharks are carnivores. Or are they? Grace CasselberryI am currently a Marine Science and Technology Doctoral student at the University of Massachusetts Amherst. I use acoustic and satellite telemetry to study the spatial ecology of lemon, nurse, Caribbean reef, and tiger sharks in St. Croix to better understand habitat selection, residency, and […]

Jumbo Shrimp: The First Definitive Evidence of a Megalodon Nursery

Where did baby Megalodon sharks hang out? In nurseries of course! Read on to learn more about how scientists identified a Megalodon shark nursery area using the fossil record! Matthew LarsenI am a second year master’s student at Coastal Carolina University in the Abel Lab. My interests focus on the ecology and life history of […]

A Species Hiding in Plain Sight

People have been catching this shark for years and have been mistaking it for its identical relative. But, scientists have now discovered that this is an entirely new species hiding in the shadow of its look-a-like. Jasmin GrahamI am a Masters student in Biological Sciences at Florida State University. I received my B.S. in Marine […]

Intent to Bite: changing attitudes towards sharks

Fear of sharks has been a long standing yet irrational notion facing beachgoers for decades. Herein we discuss how we may be able to curb this fear to change public opinion and promote conservation efforts of many species. Carolyn WheelerI am currently a PhD student studying marine science at the University of Massachusetts Boston, with […]

Ecotourism may impact white shark activity levels

Herein we discuss new research using accelerators to investigate if wildlife tourism (for example cage diving) impacts activity in white sharks. The outcomes of this study have implications not only for tourism regulation but also provide insight on possible ecosystem effects. Carolyn WheelerI am currently a PhD student studying marine science at the University of […]

A new take on disco fever: using “the disco effect” to save sharks

Happy Shark Week! In this article we discuss the potential use of disco-like stimuli to deter various species sharks from being accidentally caught in fisheries. Carolyn WheelerI am currently a PhD student studying marine science at the University of Massachusetts Boston, with my research based at the New England Aquarium. My research interests center around […]

Stuck in the middle with you: The trophic ecology of Caribbean reef sharks and large teleost coral reef predators

We often think of sharks as the top of the ocean food web, chowing down on seals and big fish to their heart’s content. That is often not the case! Where does the Caribbean reef shark fall in this hierarchy? Let’s find out. Grace CasselberryI am currently a Marine Science and Technology Doctoral student at […]

Hungry Shark: Examining the diet of tiger sharks in South Africa during different life stages.

Tiger sharks aren’t shy when it comes to their diets! Check out this article to read more about how these predators vary their diets off the coast of South Africa. Matthew LarsenI am a second year master’s student at Coastal Carolina University in the Abel Lab. My interests focus on the ecology and life history […]

A Tree of Life Project With Some Serious Bite

If you have any intererst in shark anatomy, ecology or evolution, find out about a must-see website designed by the Chondrichthyan Tree of Life Project. Jasmin GrahamI am a Masters student in Biological Sciences at Florida State University. I received my B.S. in Marine Biology and B.A. in Spanish at the College of Charleston where […]

Saving Sawfish: Using local knowledge to study critically endangered species in remote areas

What if I told you sharks have cousins that are so morphologically distinct, they swim around sporting a toothy, chainsaw-like projection between their eyes, called a rostrum?  Now what if I told you that largely because of that unique rostrum, these are some of the most endangered shark relatives in the world?  Don’t lose hope!  […]

A Race for Recovery: can reef shark populations recover in no-take marine protected areas?

In this article we discuss the use of marine protected areas in relation to an apex predator of the ecosystem, the grey reef shark. There is sizable evidence that these types of protections can help populations recover from over-fishing, providing a hopefully method moving forward in shark conservation. Carolyn WheelerI am currently a PhD student […]

Homebodies on the move: Documenting partial seasonal migration in mature nurse sharks

If I asked you to name a migrating shark, you might list pelagic ocean rovers like the white (Carcharodon carcharias), shortfin mako (Isurus oxyrinchus), or maybe even the filter feeding whale (Rhincodon typus) shark. I would be willing to bet that no one would say “the nurse shark of course!” With their new paper, long-time […]

Citizen Science and Undersea Stars: The Value of Photographs to Global Megafauna Biology

Check out this article about how tourist pictures of whale sharks are helping scientists learn about whale shark populations around the globe! Matthew LarsenI am a second year master’s student at Coastal Carolina University in the Abel Lab. My interests focus on the ecology and life history of large marine megafauna with a central focus […]

The Great Migration: Blacktip Sharks

Over ten thousand sharks gather off the coast of Palm Beach, Florida in one of the most impressive migrations in the animal kingdom. A research team from Florida Atlantic University has been quantifying and monitoring this massive migration since 2011. Check it out! Jasmin GrahamI am a Masters student in Biological Sciences at Florida State […]

Danger in the deep: uncovering the vertical movement patterns of vulnerable deep-sea sharks

Deep-sea sharks are one of the most poorly studied groups of animals on the planet, yet, their populations are highly threatened by fisheries bycatch. Scientists in The Bahamas develop new field approaches to begin unearthing the vertical movements of a vulnerable deep-sea shark, the Cuban dogfish, and their findings from could help significantly reduce fisheries […]

How our Fear is Killing Sharks

Through my journey as a shark defender, I have realized the most challenging obstacle to tackle is the fear of sharks, rather than the actual killing of sharks; most people never encounter a shark in their lifetime, yet they are still scared of them and therefore don’t take the time to think much about shark […]
