An unidentified sleeper shark of the genus Somniosus - possibly the southern sleeper shark - is filmed swimming by a Brazilian oil platform at a record depth.

A basking shark washed up on shore near Locke Island. Basking shark sightings - dead or alive - anywhere in Canada during the winter are a very rare occurence.

A sand tiger shark (Carcharias taurus) was caught by a fisherman in a New Brunswick river at the head of the Bay of Fundy. The shark may have followed the warm currents created by recent hurricanes and tropical storms.

A white shark was caught this week in the Bay of Fundy, the first confirmed great white shark sighting in Atlantic Canada in more than six years.

A spate of mysterious seal deaths is being blamed on boats rather than sharks. Scientists investigating "corkscrew" cuts on carcases washed up at two estuaries have ruled out marine predators as the cause of the lacerations. Similar cases around a Canadian island have been put down by scientists there to the Greenland shark...

A GEERG team successfully searched for and tagged a Greenland shark in the St. Lawrence Estuary on October 14. The team composed of Jeffrey Gallant, Jean-Yves Forest, and Blaise Barrette (Underwater Observers Network), took advantage of a brief interlude between storm systems to dive in the Baie-Comeau area...

Volunteer scientists studying large sharks in the St. Lawrence Seaway are seeking help from the public. Their research on the little-known Greenland shark, funded by their own money and private donations rather than government grants, just got a boost in the form of a donated boat...

Scientists are baffled by the mutilated carcasses of dozens of seals washing up on the British coast this summer, each bearing near-identical and as yet unexplained "corkscrew" lacerations... One clue has been the experience of researchers in Canada where similarly injured seals were recovered a decade ago in the Gulf of St Lawrence...

The carcass of a Greenland shark (Somniosus microcephalus) washed up on a beach in Matamec on August 15. Photo analysis would suggest it was an immature female of approximately 2.5 m. Cause of death is unknown. No external injuries were apparent. Unfortunately, the lower jaw...

GEERG conducted several media interviews after multiple shark observations and captures were reported in the St. Lawrence Estuary (Port-Cartier, Rivière-Pentecôte, Sainte-Anne-des-Monts, and the Mingan Islands). After photo analysis, GEERG confirmed that the specimens were all porbeagle sharks (Lamna nasus), including...

It's a staple of Hollywood, and the dramatic peak of many a film - that gut-wrenching moment when the hunter realises that he has just become the hunted. It happened in real life to Canadian diver Jeffrey Gallant when the tables turned in his multi-year quest to find an elusive giant predator in Canada's saline rivers. When a massive dark...

Scientists have been stunned by the discovery of a shark that had eaten a polar bear... Jeffrey Gallant, the co-director of a Canadian-based shark research group, said: "There's no possibility a Greenland shark could predate a live adult white bear, unless it was injured or seriously ill." He said the Greenland shark would not be able to afford the risk...

In June 2003, Chris Harvey-Clark and Jeffrey Gallant uncovered a unique location where sharks were found in dive-able depths. The pair returned to the site with a VideoRay in August, an 8-pound underwater robot equipped with a video eye that could descend to depths of 500 feet. Here, they would try to document the shark...
