Meet Lisha, the great white shark going where no sharks have gone before.
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.

A real journeywoman, Lisha has traveled where most great whites fear to swim. This young wayfarer has racked up an incredible 30765 miles since being tagged by Ocearch in 2012 and her incessant travels show no signs of slowing down.
Lisha has traveled further south than any other shark in her community, and regularly visits unchartered waters in the mysterious Southern Ocean. She does not feel the cold like her companions and has no trouble traveling in freezing waters for days on end, exploiting the untapped fish supply, which exists due to the lack of predators roaming the cold waters.
She is also a fan of the Mozambique coastline where she enjoys the respite of the cold Atlantic in warmer waters but rarely sticks around for too long, preferring to continue on her adventures.
Currently, she is in her home bay of Gansbaai where she is organizing a migration for younger sharks interested in travel and is expected to set up an expedition to the Southern Ocean sometime in the New Year.
