Meet Cyndi, the great white shark who traded the cold for the warm.

Ocearch’s tracking technology allows researchers to monitor sharks movements throughout the world’s oceans, providing valuable insight into their behavior and their range.

Each shark is tagged with a tracking device that is inserted through their dorsal fin, and whenever they break the surface of the water, a signal is transmitted to a satellite. The satellite then sends back an estimated location of the shark.

Each of these ‘pings’ give researchers an accurate, real time location of a particular shark, allowing them to collect data about each individual.

During the tagging process, tests are done on the shark which determines their species, age, sex, weight, length and stage of life. From the data collected a profile is then setup for the shark on Ocearch’s official tracking website.

This process allows researchers to glean the extent of the shark’s territory, the distance they have covered since their tagging and monitor their behavior.

This information provided educates readers, not only about the current shark population and their behaviour, but also about OCEARCH’s conservation initiative.

Expectedly, each shark displays their own particular habits, which coastlines they prefer and the depth at which the like to swim. It’s interesting to follow a particular individual and see what they get up to, how much distance they cover in comparison to other sharks and whether they prefer shallow or deep waters.

Stage of Life: Immature

Total distance covered: 18625.420 miles

Tagged in Gansbaai in April 2012, Cyndi has been one of the busier sharks tracked by Ocearch in the last couple of years and has propped up a number of times across the entire South African Coast and Mozambique, while also spending time around the island of Madagascar.

Having traveled a mammoth distance of 18625.420 miles, Cyndi has traveled further than almost any other tagged shark since being picked up by Ocearch and has displayed a fondness for the warm waters in the Indian Ocean despite being a local of the colder waters off  the coast of the Western Cape.

With frequent trips further south into the Southern Ocean, there isn’t much Cyndi hasn’t seen throughout her range and her impressive mileage means she is the perfect tour guide amongst her community.

Cyndi’s adventures have paved the way for other sharks from Gansbaai, who are usually more than happy to stick to their familiar playground, to take trips along the coast and see what the Eastern part of South Africa has to offer.

Despite this, Gansbaai is still home and visitors to this great white shark tour hotspot will have numerous opportunities to see Cyndi and her mates whichever time of the year you choose to go shark cage driving.
