The Voyage Bracelet

“In order to conserve and manage sharks, researchers use tags to track them in their natural habitat and study their movement patterns and behavior. This tagging allows researchers to better understand the species’ life history, social behavior, reproduction and much more, including how often the animals may interact with fisheries. These fields are all very important for advancing the conservation and management of sharks. For example, Saving the Blue recently tagged a great hammerhead in Andros. Within the Bahamas, this shark was protected as part of the national Shark Sanctuary. When the shark left the Bahamas and swam to the United States, however, it was subject to fishing pressure as regulations permit limited harvest in federal waters. By revealing where sharks move and the routes they travel, scientists can understand how best to influence management and ultimately, protect them. This protection is only possible with the use of tags, which reveal the secrets of these fascinating creatures!” - Saving the Blue

“We use a combination of satellite and acoustic electronic devices. Satellite tags (SPOT or PSAT) are typically used to monitor migration patterns both horizontally and vertically as they can provide locations of the sharks during tracks and depth / temperature information at 5-minute intervals throughout their deployment. Acoustic tracking tags are usually deployed to examine habitat use at finer scales, determining the role of various biological factors (e.g. biotic / abiotic) on how sharks use particular areas.” - Saving the Blue

“Our team is very careful with how we handle and place tags on sharks. Most satellite devices are placed next to or through the dorsal fin. There are no nerve endings in the fins and although we are unable to ask a shark if it feels us making a hole to place a tag, they do not react. The tags are temporary with materials that break down over time, so eventually there are no tag remnants on the shark. Acoustic tags are typically implanted in the body cavity and can last up to 10-years, many recent studies that our scientific team have been involved with have tracked some individuals up to 6-years with tags implanted showing no adverse effects.” - Saving the Blue

Sharks’ biggest fear is the bottlenose dolphin. Though dolphins are known to be friendly and gentle creatures, they can be skilled fighters when in conflict with sharks. Sharks fear them because they know that dolphins can use their pointed snouts to injure the sharks’ sensitive underbellies.

Despite their scary appearance and reputation, sharks can actually be relatively friendly towards humans. There are hundreds of different shark species, so this can vary. However, most shark species do not mind close human contact and interaction.

Even though sharks certainly have the ability to attack humans, they typically do not have reason to and would prefer to attack and prey on other marine animals. Because humans are not a preferred food source of sharks, shark attacks on humans are actually very rare.

Because there are many species of sharks, the variation in size can range from sharks that are small enough to fit in your hand to sharks that are larger than a school bus. The biggest shark is the whale shark, which can grow to be up to 60 feet long.

Shark tracking bracelets work using satellite technology through a small tag, typically placed on one of the shark’s fins. This tag sends signals up to an overhead satellite, telling its precise location and allowing for its movements to be tracked.
