Have you ever wondered how sharks utilize their gills? There’s a common myth that all sharks must be continuously swimming in order to continue breathing, but this is only true for the pelagic or open water species of sharks. They use a method called ram ventilation which forces the flow of water over their gills as they move forward. Benthic and semi pelagic sharks can utilize ram ventilation, but have also adopted a different way of breathing called buccal pumping. This method is used to pump water across their gills with the power of their cheeks and is typically used when they are resting on the bottom of the ocean (Alexis L. Morris, Elisa J. Livengood, Frank A. Chapman, 2015). When fisherman use longlines (usually in pelagic zones and sometimes for up to 12 hours at a time) obligate ram ventilators are at an especially high risk to become bycatch. When caught on a line, they will suffocate because they can’t move forward to pass water over their gills (Tripp, 2016). In the Pacific Ocean alone, 3.3 million sharks are caught each year as bycatch on longlines (World Wildlife Fund). A great way to take action is to choose seafood that is fished or farmed in ways that have less negative impact on the environment (Jordan T. Watson, Keith A. Bigelow, 2014). Check out the app Seafood Watch for an easy way to tell where your fish is coming from!
Wildlife tourism, including cage diving with white sharks (Carcharodon carcharias), has become a growing attraction in many regions around the world (Huveneers et al. 2013). Due to the nature of the activity, cage diving is considered quite controversial because of the associated negative stigma surrounding white sharks (Bruce and Bradford, 2012). Some have raised concern over the idea that cage diving could lead to an increase in attacks through conditioning of the sharks (Johnson, 2006). The idea that sharks can be conditioned to associate the presence of food with humans comes from the action of cage diving operators luring sharks to their boats by chumming the water (Johnson, 2006; Bruce & Bradford, 2012). To dispel this unjustified fear, Johnson conducted a study on whether white sharks in South Africa showed signs of conditioning to cage diving boats. He discovered that white sharks spent less time near cage diving boats with more experience, which is the complete opposite response the sharks should have had if they were associating cage diving boats with food rewards (Johnson, 2006). In fact, Johnson found that white sharks in South Africa may be associating chumming with less desirable scavenging opportunities when compared to hunting live prey. Additionally, sharks would not associate humans with food due to the major differences in both olfactory and visual stimulations that they would receive in the different scenarios of a cage diving boat and a surfer, for example (Johnson, 2006). People are continuing to brand white sharks with a negative reputation based on ideas that have no compelling evidence to support them, when many operators actually promote conservation and support research. The opportunity of seeing these animals firsthand is an invaluable experience that can help change perceptions. The only way people people are going to stop seeing them as monsters is by seeing these animals for themselves, and the only way this can be done reliably is with the use of bait and a cage. #SpeakUpForSharks and help put an end to the negative myths surrounding them!

While each species of shark is special in its own way, tiger sharks are one of my favorite sharks to photograph and interact with and I’m always hoping that one will show up whenever I visit the aggregation site in Hawaii. Tiger sharks are mostly nomadic; however, some studies are suggesting that there are some resident tiger populations like the ones at Tiger Beach in the Bahamas. Unfortunately, my sightings and interactions for this species have steadily declined over the years. 10 years ago, we would could see as many as 8 tigers in the water at different aggregation sites. Now we are lucky to see even one every couple of months. Tiger sharks are considered near threatened by the IUCN red list based on an assessment conducted in 2000, and based on the declines that I have personally observed as well as reports from others around the world tiger sharks are in desperate need of greater protection. For me every week is shark week, and I am extremely grateful for the chance to educate others about the true nature of these animals and how threatened they really are. For everyone tuning into this year’s program please consider learning more about the reality of these misrepresented animals and consider going to see them for yourself in the wild with a responsible shark ecotourism operation. #DiscoverSharks#SaveSharks#SharkConservation#JuanSharks#OneOcean#SharkWeek@Discovery#July23
