Culling sharks won’t protect surfers
By George Burgess, University of Florida The warm and productive waters of La Réunion, an island east of Madagascar in the Indian Ocean, are home to many types of tropical sea life, including apex predators such as sharks.

Majorca white shark sighting first in decades
A great white spotted off the Majorca coast might be the first in four decades. Researchers from the marine conservation group, Alnitak, spotted what is believed to be the first white shark in waters off Spain’s Balearic Islands in over 40 years.

Tracking study reveals peculiar behavior by great white sharks
A new study published by Scientific Reports found that great white sharks in the Atlantic often dive to great depths to hang out in deep-water whirlpools along the ocean floor. The study, conducted by the University of Washington and Woods Hole Oceanographic Institution, examined adult female white sharks in the Gulf Stream and North Atlantic […]
Study shows shark behavior altered by ecotourism activities
A recent study published in Conservation Physiology found that great white sharks become more active in the presence of humans taking part in caged shark dives. While ecotourism such as cage-diving activities has helped spur conservation-minded attitudes among participants, the impact on the sharks being exposed to such activities had not been thoroughly studied. Great white-centric […]

Scientists estimate white shark populations off Australian coast
According to research from CSIRO, approximately 8,000 great white sharks roam the waters off Australia. Using genetic and statistical analysis of DNA extracted from juvenile sharks, the total population estimate included about 2,210 sexually mature adults. Using statistical methods, the researchers were able to estimate how many adults had produced juveniles. Researchers hail the study, […]
