Great white shark weighing over 900 kilograms passes North of Bahamas

According to a non-profit organization OCEARCH, a great white shark weighing over 900 kilos returned to the waters of the northern Bahamas.

The 4.4-meter (nearly 14.5-foot) female shark named Lydia has been tracked since March 2013 by a GPS device. The shark has traveled more than 55,500 kilometers (34,500 miles) since she was tagged with a locator device off Jacksonville, Florida, on March 3, 2013.

It has travelled over the mid-Atlantic ridge toward Europe and western Africa then back again. OCEARCH has made a Twitter account of Lydia, which has provided the first ever details about great white sharks over the last two years.

Almost 3,000 Twitter fans are following the shark, which is believed to be in her late 20s or early 30s. They can trace Lydia's exploits each time her fin breaks water, pinging new data by satellite to computer trackers.

Researchers hope that the battery on her fin device would hold out for another three years. This will allow them to know where she might give birth.

Gregory Skomal, a senior scientist at the Massachusetts division of Marine Fisheries, mentioned that by understanding Lydia's habitat, conservation plans to protect great whites can be crafted.

He said, "Is she going to reveal for us nursery areas for white sharks? We're hoping that as the patterns emerge from sharks like Lydia, we're able to tease out some of these aspects of the natural history of the animal that we just don't know".

According to him, a progress in technology in the last decade has made it possible to trace such a far roaming creature so closely for so long.

Chris Fischer, chairman and expedition leader for the Ocearch, hoses were put in the shark's mouth to allow her to breathe as a team of scientists conducted about 12 research projects in 15 minutes including blood samples.
