‘Living fossil’ species found in south Pacific

Fri, 19 May 2006

French scientists exploring the south Pacific said Friday they have discovered a new species of crustacean thought to have gone extinct 60 million years ago.

The 12-centimetre-long female “living fossil” — looking like a cross between a mud lobster and a shrimp, the researchers say — was found 400 metres under water during an expedition northwest of New Caledonia, a French territory east of Australia.

The specimen has been dubbed Neoglyphea neocaledonica, the National Museum of Natural History and the Research Institute for Development said in a statement.

Marine biologists Philippe Bouchet and Bertrand Richer De Forges found the new species in October while trolling in a remote area between New Caledonia and Australia.

The specimen’s large eyes, red spots and thick body meant it was a different species from Neoglyphea inopinata, the first member of the rare group ever identified, found in the Philippines in 1908.

  1. Team discovers new giant lobster species

    December 11, 2006 – 3:29PM

    An international research network announced on Monday the discovery in the past year of marine species including a giant rock lobster, beaked squid and “Jurassic” shrimp.

    The Census of Marine Life, funded partly by the United Nations and networking researchers in more than 70 countries, calls for intensified research and conservation efforts, saying the lobster, for example, is feared to have decreased to a level close to extinction.

    The rock lobster, weighing 4 kilograms with the main part of the body spanning half a metre, has been found off Madagascar by South African researchers, the group said as it released its 2006 Ocean Census report.

    The lobster has been determined as a new species by the size and gene analyses, named Palinurus barbarae.

    Separately, about 60 species thought to be new discoveries have been found in the deep Atlantic between Iceland and Portugal, including a squid with a hard beak looking “quite capable of chewing its food,” it said.

    Discoveries elsewhere include a shrimp, off Australia, similar to one believed to have become extinct 50 million years ago, and 12 likely new crustacean species in the Sargasso Sea, it said.

    The group aims at a project to survey many species in the seas in the world and put them into database by the year 2010.

    Some Japanese researchers are taking part in the network, including those from Hokkaido University and Kyoto University.

  2. Namibia: Over a Tonne of Lobster Back in Ocean

    Thousands of rock lobsters, weighing over a tonne in total, were released back into the ocean yesterday after being kept at the Swakopmund Aquarium for the last three weeks to avoid exposure to the deadly red tide that affected the central coast recently.

    A marine biologist at the Ministry of Fisheries and Marine Resources, Deon Louw, said seawater conditions had stabilised enough to return the lobsters.

    For the past three weeks, oxygen levels in the sea had been depleted by intense algae blooms.

    This killed large numbers of marine creatures.

    The oyster industry suffered a tremendous blow, and the rock lobster stock was also decimated.

    People collected tonnes of lobsters that had washed ashore, ignoring the size restrictions protecting the resource.

    By law, a person may catch only seven reasonably sized lobsters a day.

    Fisheries officials had their hands full containing the free-for-all, and the best option was to collect large numbers of lobsters and keep them in the aquarium until the red tide had passed. Louw thanked people who had helped with the rescue effort, saying that about 90 per cent of the lobsters brought to the aquarium had survived to see freedom again.

    He said the duration of the red tide was unusually long, and that such severe outbreaks were rare. Stricter measures will be used in future to enforce the law and prevent excessive looting, he said.

    These will include stepping in sooner to remove lobsters to the aquarium. The season for recreational lobster catching is ending at the end of April, and will resume on November 1.

    It is expected that there will be fewer lobsters to go around next season because it takes about seven years for them to reach the legal size.
