Shark Tagging & Tracking: Separating Fact from Fiction

For several years now, I have been using electronic tagging to study the movements and behaviors of sharks. You can find out more about this research HERE and watch a video HERE.   I previously wrote about the state of electronic tagging and tracking marine animals. However, recently there have been a lot of myths,…

Electronic Tagging and Tracking Marine Animals Supports Conservation

Understanding and predicting animal movement is important as it is central to establishing effective management and conservation strategies [1]. Until relatively recently, studying the movements and behaviors of highly migratory marine species (turtles, sharks, whales, penguins, seals and billfish) have been challenging due to the logistical and technological constraints of working in aquatic environments. However,…

Hammerhead Shark Photos From “Exhilarating” Dive

I just returned from an incredible trip scuba diving with great hammerhead sharks. This was one of the most exhilarating experiences of my life. While underwater I was amazed by these awesome predators. I was able to capture a series of photos (both during day and night) of these mysterious creatures.   As you look…

A Key tool for Saving our Oceans

Over the past 20 years, scientists have been assembling compelling data that show the world’s oceans are in deep trouble. Once-abundant species are disappearing, habitats are being destroyed, and fisheries are collapsing across the globe (Jackson et al. 2001, Lotze et al. 2006). For example, studies estimate that biomass of tunas and billfish have decreased…

Excuse Me Waiter, But There’s an Endangered Species in My Bowl of Soup!
