Great white shark, video, and its fossil relative Procarcharodon


This video is called Best Shark Attack Video – gigantic Great White Shark in South Africa while Cage Diving. It is about a great white shark, as filmed from a cage with divers inside.

Here is information on its fossil relative Procarcharodon, at 10 metres long still bigger, from the Oligocene period.

I am learning slowly how to embed videos in this blog; and I hope to do more.

  1. Chinese know little about shark conservation: survey

    BEIJING (Reuters) – There is growing public support in China for the need to protect the world’s dwindling shark population, but little understanding about the connection between conservation and shark finning, according to a survey.

    Shark fin, once offered as a gift to emperors, is traditionally served at Chinese wedding banquets and occasions when the host wants to impress guests with expensive and unusual dishes.

    Some also believe it is good for health.

    The U.N. Food and Agricultural Organization estimates 100 million sharks are caught each year, though experts say the real figure could be twice that, leading to a dramatic drop in the populations of some species.

    “If you can stop people consuming shark fin soup, it would relieve a huge pressure on the species,” Steve Trent, president of conservation group WildAid, told Reuters at the unveiling of the survey.

    “This is something where individuals at home, work and places of entertainment, can have a real impact,” he added.

    Activists say finning is incredibly wasteful, with sharks simply dumped overboard to bleed to death after their fins have been hacked off. The industry disputes this, saying to be that wasteful makes little economic sense.

    In China, which accounts for more than half global shark fin consumption, people know little of the problem, thinking sharks are fierce killers, and that eating their fins is good for the health and a demonstration of wealth, the survey found.

    Great white shark sets 3,000 kilometre swim record

    Wellington – A great white shark, electronically tagged in March in New Zealand, has swum more than 3,000 kilometres to Australia’s Great Barrier Reef, it was reported Monday. The journey of the 4.4-metre female shark, named Kerri by scientists, was the longest swim recorded in New Zealand, according to the National Institute of Water and Atmospheric Research (NIWA).

    It was the first evidence that great whites, which are protected in New Zealand waters, do travel to Australia, a NIWA statement said.

    The shark was given an electronic “popup” tag by a team of scientists from New Zealand, Germany and the United States in March at Stewart Island.

    The tag records location, depth and temperature and floats to the surface after a pre-determined time, transmitting data to a satellite, which emails the results to the scientists’ computers.

    The tag began calling home on December 18, but it will be another 10 days before all its data is received.

    “At this stage, we don’t know what route Kerri took or how quickly she travelled to Australia,” said NIWA fisheries scientist Malcolm Francis.

    Department of Conservation scientists Clinton Duffy said: “Our tagging results show these sharks can be highly mobile.

    “Australian tagged sharks have turned up in New Zealand waters, and now, for the first time, we have evidence that this is a two-way process. Our results suggest that white sharks in the south-west Pacific may comprise a single population.”
