A recent stranding of a basking shark (Cetorhinus maximus) in north-western Bali is the first confirmed record of this large, filter-feeding shark species in Indonesian waters. The shark was an adult male. It is possible that the Indonesian throughflow – the warm ocean current which moves water from the Pacific to the Indian Ocean – is […]
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. […]
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 […]
Good news at last for sharks: prices and sales of shark fin are falling in China by 50-70% according to a report by WildAid.
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 […]
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 […]
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 […]
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.
Shark feeding dives are increasing, yet are controversial. Shark tourism has great economic benefits, and can help shark conservation. What are the drawbacks?
Great white sharks may be among the longest-lived fishes. New study finds the shark can live over three times longer than previously estimated, which may mean it is even more vulnerable than thought.
