Sharks: Historical and Future Predictions
Given your familiarity with the extinctions and subsequent radiations of the cartilaginous fishes, what do you believe would happen to the abundance and diversity of the sharks, rays, and chimaeras if the climate warms in the future? (Kimley, P. 2013). Radiation...
SHARK BIOLOGY TALK- Q&A
Why do sharks, rays, and chimaeras possess specialized organs such as the salt gland, kidney, and gills to maintain their inner ionic composition? Chondrichthyans must adapt to a range of environments. Therefore, the chemicals and salt found within their bodies and...
BIOMECHANICS OF COMPLICATED SHARK MOVEMENTS
Can you explain the biomechanics of more complicated movements such as rolling and relate these to the pilot’s control of a fighter airplane? This topic is covered in an article titled “Three-dimensional kinematics and wake structure of the pectoral fins during...
Breaching 101
That moment. The anticipation. Will it happen? It seems like I am waiting forever for it to happen; the forever is inevitable. Then it happens. In slow-motion it seems, like my heart stopped. The awe-inspiring Polaris breach of a Great White shark. But why do they do...

The History of Jupiter, Hobe Sound, and Tequesta Florida
The Jupiter we know and love today is the best-kept secret in Florida, and maybe in the nation. It is also one of the best places on the planet to dive with sharks!
Environmental Changes Impact Shark Behavior: Local Impacts, Causes and Customized Unmanned Systems Used in Solutions
HAB’s, or harmful algal blooms, and how they have a negative and toxic impact on the local marine environment as well as humans. These environmental and habitat changes directly impact the marine apex predators, sharks. These changes aren’t limited to a single or one particular species, but multiple species. This paper identifies a viable solution in monitoring and possibly eliminating HAB’s. The solution is a combination of innovative technologies, autonomous biosensors and unmanned systems capable of flight and underwater propulsion.
Vertigo and Diving
Very soon after I started diving, in fact, during my last open water dive before I became a certified diver, I discovered something a lot more terrifying than swimming freely with an apex predator twice the size as me. And I was in less than 20ft/6m of water. I felt...
