Most Caribbean coral reefs may disappear within 20 years, if something isn’t done, a new report warns – but for once global warming is not to blame.
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 […]
For the first time, Britain’s Royal Mail has issued stamps championing an environmental issue – and that issue is over-fishing.
Fish living in deep waters on the continental slope around the UK play an important role carrying carbon from the surface to the seafloor. It has been assumed that deep water fishes all depend on particles that fall from the surface for their energy. These bottom-living deep water fishes never come to the surface and […]
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 […]
Over 42,000 turtles are legally killed each year, 80% of them endangered green turtles (Chelonia mydas), a study suggests. British scientists investigated which countries allowed turtles to be killed, and how many of each species died, the Diversity and Distributions Journal reported. Ten countries account for more than 90% of the catch, with Papua New […]
Numbering just 500, the North Atlantic right whale (Eubalaena glacialis) is one of the rarest animals in the world. The whales have been hunted nearly to extinction. Now protected, their biggest threats are being hit by ships and entanglement in fishing gear. With no progress in reducing entanglement deaths, reducing ship collisions has become even […]
But not by astronauts or space tourists. Scientists from the British Antarctic Survey are using satellite images to detect and count southern right whales (Eubalaena australis). In recent years there have been over 420 deaths of these whales in their nursery grounds at Península Valdés in Argentina. (Out of a population last estimated at 2577 […]
What makes the Cuttlefish so good at controlling its colour and blending in with its surroundings? This month scientists at Harvard University and the Woods Hole Marine Biological Laboratory have helped answer that question. It has been long known that the skin of the Cuttlefish contains chromatophores: yellow, red, and brown pigmented sacs that the […]
