Great white shark

Like Sharks? Volunteer with Great White Shark Project

The 1974 film “Jaws” immortalized the Great White but also did more damage to the image of the Great White Shark than they could ever do themselves. Despite all the fear and celebrity, very little is known about these aquatic behemoths. Scientists who have studied Carcharodon carcharias (jagged tooth) aren’t even sure how they reproduce. […]

Shark loss hits global ecosystems

The loss of sharks could contribute to the destruction of one of the planet’s most under-appreciated sources of carbon storage — seagrasses, according to FIU researchers. Not that sharks eat the seagrass, they don’t, but they do eat the turtles which feed in the seagrass meadows. Add this to the problems of pollution, mooring and […]

Endangered Sawfish Strategy Launched

Plan to save sawfish – most endangered fish in the sea

The International Union for Conservation of Nature (IUCN) has released a global strategy to prevent extinction and promote recovery of sawfishes. The strategy by the IUCN’s Shark Specialist Group was launched at the Sharks International conference in South Africa and coincides with announcements that two West Africa countries – Guinea and Guinea Bissau – are […]

Grey Reef Shark, Carcharhinus amblyrhynchos

Shark-counting divers become citizen scientists

Divers monitor reef shark numbers as accurately, and cheaper, than automated tracking tools, a study suggests. Shark populations are thought to be declining globally, but a quick search of the IUCN’s Red List shows that for 67% of shark species the population trend is unknown. It’s difficult to monitor shark numbers due in part to […]

Little Support for Shark Culling

Following another fatal shark attack in Australia, new research finds little support for the shark cull. A survey of 583 aquarium visitors asked people how they thought the Government should respond to shark bites and found that despite the public’s fears, 87 per cent favoured non-lethal responses. Only four per cent of those surveyed supported […]

Extinction Threatens Quarter of Sharks and Rays

A quarter of sharks and rays are threatened with extinction. Large, shallow-water species are at most risk. The Indo-Pacific, particularly the Gulf of Thailand, and the Mediterranean Sea are the two ‘hotspots’ where the depletion of sharks and rays is most dramatic. The Red Sea is also home to a relatively high number of threatened sharks and rays.

Lions Mane Jellyfish

Have you seen Basking Sharks, Jellyfish or Turtles in UK Waters?

The Marine Conservation Society wants to know if you’ve seen any basking sharks, turtles or jellyfish – in UK and Irish waters. Jellyfish? Yes, because jellyfish are the favourite food of Leatherback Turtles. And they don’t just want to know about live jellyfish but about strandings on beaches as well. Identification of live jellyfish is […]
