Sawfish and hammerheads – we’ve got shark sightings and here’s what you need to know!

It was a rare occurrence, and for Florida Atlantic University’s resident shark expert Stephen Kajiura, Ph.D. – it happened twice.  Kajiura has photographed millions of sharks – but this sighting was no regular day on the water.


“The first sawfish was near Boca Raton and was seen swimming southbound in shallow water. He estimated it to be about 9 feet long. The second one was near MacArthur State Park on Singer Island and a little larger. Sawfish can grow as large as 17 feet in length.


Kajiura's sawfish encounters are the latest in a regular string of encounters reported by anglers, divers and researchers. In recent years, sawfish have been caught and released by Florida anglers fishing from beaches for sharks, or in inlets for tarpon. Sawfish have become regular catches for anglers fishing the waters of the Indian River Lagoon, Everglades National Park or the waters of Charlotte Harbor. “ - TC Palm – USA Network


That was last month, however, just recently, a large hammerhead shark was coming dangerously close to shore, raising some cause for concern about swimmer safety.


Lifeguards closed the Nokomis Public Beach for close to an hour until the enormous fish had departed for deeper waters.  The encounter left some scared and some curious – looking to catch a glimpse or picture of the gigantic shark.


  • So, what do you do when a shark comes close to shore?
  • How dangerous is it?
  • How can experts or event he public tell when a shark is aggressive or just passing by?
  • Sharks do call the ocean home – what do we all need to do to exist in harmony?


Are you covering? Do you need to know more about sharks, the dangers they pose and what we really need to be concerned about and even break down some of the myths and legends about just how concerned humans need to be about these predators? Let our experts help.

Ahead of Back-to-School, FAU’s Dr. Sameer Hinduja Says Instilling Hope in Teens Can Shield Them from Bullying – Online and Off

Dr. Sameer Hinduja is one of the world’s foremost experts on cyberbullying, adolescent mental health, and digital safety. A Professor at Florida Atlantic University’s School of Criminology and Criminal Justice and Co-Director of the Cyberbullying Research Center, he has advised the White House, testified before federal agencies, and worked with schools and tech companies worldwide to protect young people online. View Full Profile→ Amid the U.S. youth mental health crisis, his latest peer-reviewed study, published through FAU Newsdesk, reveals that hope not only boosts well-being and academic achievement but also acts as a powerful shield against bullying and cyberbullying in adolescents. Results, published in the journal Frontiers in Sociology, show that students with less hope were 56% more likely to cyberbully others than their peers over their lifetime, and 57% more likely over the last 30 days. Those with more hope were 36% less likely to cyberbully others over their lifetime and over the last 30 days when compared to their peers with lower levels of hope. The key takeaway? Hope matters. It buffers against the urge to aggress against others online and off. “Hope acts as a powerful protective factor against both school bullying and cyberbullying among youth,” said Sameer Hinduja, Ph.D., lead author, a professor in the School of Criminology and Criminal Justice within FAU’s College of Social Work and Criminal Justice, co-director of the Cyberbullying Research Center, and a faculty associate at the Berkman Klein Center at Harvard University. “When young people believe in their ability to set meaningful goals and stay motivated to reach them, they are far less likely to lash out or harm others. Hope gives them a sense of direction – and that can make all the difference.” Hinduja's previous research has been featured in The Washington Post, where he emphasized that cyberbullying is not just emotionally distressing—it can cause trauma responses in teens that mirror clinical Post-Traumatic Stress Disorder. “As our research clearly shows, cyberbullying in any form — whether it’s exclusion from a group chat or direct threats — can lead to significant trauma in youth,” Sameer Hinduja, a professor in Florida Atlantic University’s School of Criminology and Criminal Justice and the paper’s lead author, said in a news release. “We were surprised to find that no single type of cyberbullying caused more harm than others; all carried a similar risk of traumatic outcomes. This means we can’t afford to dismiss or trivialize certain behaviors as ‘less serious’ — being left out or targeted by rumors can be just as detrimental as more overt attacks.” Why This Matters Now As students return to school this fall, Hinduja’s research offers a clear reminder: digital harm is real harm. Emotional safety in online environments deserves the same urgency as physical safety in school buildings. His work calls for: • Preventive education over punitive responses • Trauma-informed approaches in schools • Support systems that validate and protect victims • Tech accountability and policy reform   ⸻ Dr. Hinduja is available for media interviews on topics such as: Adolescent Mental Health • Cyberbullying • PTSD • Digital Safety • School Culture Click on the icon below to connect.

North Atlantic Sargassum Bloom Hits Record Levels – and Florida is Feeling the Surge, One Expert Says

Dr. Brian LaPointe, Research Professor at Florida Atlantic University’s Harbor Branch Oceanographic Institute, is one of the nation’s most recognized experts on marine ecosystems. His work spans algal physiology, biochemistry, biodiversity, and coastal conservation — with more than a decade of dedicated research focused on the rise and impact of sargassum blooms across the Atlantic. LaPointe confirmed that sargassum levels in the North Atlantic have hit a new biomass record — and much of it is now washing ashore across South Florida’s coastlines. The scale of this bloom, he says, could have lasting consequences for marine ecosystems, tourism, and public health. LaPointe recently spoke to CNN about why this record bloom is raising alarm bells: “Sargassum goes from being a very beneficial resource of the North Atlantic to becoming what we refer to as… a harmful algal bloom when it comes ashore in excessive biomass.” Ammonia is another problem emitted by the decaying seaweed, LaPointe noted. The chemical compound “strips the oxygen out of the waters along our coastal ecosystems like mangroves, coral reefs, seagrass beds,” he said. The scale of the bloom is staggering. According to University of South Florida estimates cited by LaPointe, over 31 million tons of sargassum have been detected this year — a 40% increase over the previous record. Dr. Brian LaPointe is available to speak with the media on this topic. For interviews, click below to view his full profile and click the connect button.

What's the True Story on the State of Tourism in Florida?

Tourism is one of the key economic drivers in Florida. The sector is responsible for approximately 10 percent of the Gross State Product (GSP), employs millions, and contributes billions to the state's economy. But how are things in the sector? It depends on the day, what you're reading or what you're watching: the industry in Florida is either booming or in a vulnerable situation. Here are two examples: Rising tariffs, visa delays, and shifting global travel trends have created a perfect storm, leading to a sharp drop in tourist numbers across Florida and several other U.S. states. The U.S. tourism industry is facing unprecedented challenges as international visitors choose alternative destinations amid political and economic shifts. According to recent data from the U.S. Travel Association, international visits to the U.S. saw a 14% decline in March, reflecting a broader global trend. However, the most significant impact has been felt among Canadian travelers, with a staggering 20.2% decrease in the number of Canadians visiting the U.S. This marks a troubling shift for the U.S., which has long relied on its neighboring country as a key source of international tourism. Florida, which has seen a decrease in tourism since the pandemic, is now facing a compounded crisis. The state, which historically attracted millions of international visitors, is seeing fewer long-term snowbirds, as well as a general decline in international arrivals. The state’s tourism sector, once a booming economic engine, is facing significant challenges. With both fewer foreign visitors and changes in local tourism trends, the state’s economy is under increasing strain. According to the World Travel & Journalism Council, the U.S. is on track to lose more than \$12 billion in international travel spending this year alone due to the decline in visitor numbers. June 06 - Travel and Tour World Whereas government officials are painting a very different picture. Florida welcomed 143 million visitors in 2024, setting a new tourism record for the state. State officials said this is the most visitors in a single year in Florida's history. The trend isn't slowing down, as more than 41 million people visited Florida in just the first three months of this year. May 21 - ABC News So there are questions that need to be answered: What is the current state of tourism in Florida? Have tariffs impacted visits from abroad? Does the high US dollar have anything to do with fewer people coming to the Sunshine State from outside of America? Has domestic travel increased with more Americans choosing Florida as a destination? If the sector is suffering from a decline in visitors, how can it adapt to be more attractive to tourists?
