MANILA, Philippines—Four new species of freshwater crab, bright purple in color, have been discovered in the biologically diverse Philippines, according to a scientific paper.

The tiny crustaceans were found in streams in remote areas of the Palawan island group, according to a team led by Hendrik Freitag, of Germany’s Senckenberg Museum of Zoology.

“They are semi-aquatic and hide in burrows at the stream bank, which are usually found under boulders and roots,” said his paper published in the latest edition of the National University of Singapore’s Raffles Bulletin of Zoology.

Their eggs hatch directly into juvenile crabs, and the creatures emerge at night to forage under water, Freitag added.

Photographs of the adult crabs published on the website of Dresden-based Senckenberg museum showed them with a purple carapace, and with claws and legs tipped red.

Scientists began extensive investigations of similar freshwater crabs in the area in the late 1980s, with one new species being found — the Insulamon unicorn — Freitag’s paper said.

More field work in the noughties led Freitag to conclude there were four other unique species.

“Based on available new material, a total of five species are recognized… four of which are new to science,” Freitag said.

The biggest, Insulamon magnum, is just 53 millimeters by 41.8 millimeters while the smallest, Insulamon porculum, measures 33.1 by 25.1 millimeters.

The two other new species were Insulamon palawense and Insulamon johannchristiani.

The four slightly differ from the first find, and from each other, in the shapes of their body shells, legs, and sex organs.

Conservation International lists the Philippines as one of 17 countries that harbors most of Earth’s plant and animal life.

    bakit ba natin pinapayagan
    ang mga dayuhang
    pakialaman ang ating
    flora at fauna
    without pilipino supervision

    sila lang nakakakuha ng parangal

    mga iyan
    matagal ng alam
    ng mga pilipinong nakatira diyan

    discovery myth na naman

    who discovered the philippines?
    as if we need discovering
    from the ignorance of foreigners

    • http://pulse.yahoo.com/_WYAZBOJYIUCRLWTYJBORBVTTOI boyfarmer

       because Filipinos are not interested in scientific study of our flora and fauna, now that you show concern, you should start to conduct scientific study para hindi tayo maunahan ng foreigners

      • http://joboni96.myopenid.com/ joboni96

        kaya nga ako may research ngayon

        ikaw meron ba?

      Actually Joboni96, madaming mga lokal na eksperto ang nagsusuri sa ating mga kagubatan at dagat. Subali’t hindi lang sila pinapansin gaano ng lokal na media. Tingin nila, iba kasi pag nanggaling yung dalubhasa sa ibang bansa, mas “news worthy”. Kung hindi mo gustong maging isang scientist, tulad ng suggestion ni boyfarmer, mag aral ka ng Journalism, at saka mag-apply ka sa mga major media tulad ng Inquirer – para mabago ang kultura.

      • http://joboni96.myopenid.com/ joboni96

        baka gusto mong tumulong
        sa ginagawa kung research ngayon

        kontakin mo lang ako
        sigurado matututu ka
        baka matuwa ka pa

        Research ba yan, o koleksyon ng mga tula?  May sampler ako:

        An Ode to Joboni96.. here it goes:

        Kaibigang Joboni,
        Ang iyong mga panunulat ay kawili-wili

        Palagi itong patula,
        Upang sa gayon ba’y magtunog na matalinghaga?
        Subali’t ito’y minsan ay nakakatulala!

        Ang iyong mga posisyong politikal,
        Gayundin ang mga komentaryong pangkalakal,
        Ay tunog komunistang radikal!

        O Kaibigang Joboni,
        Sa iyong mga pagmunimuni,

        Palawakin ang kaisipan,
        Para sa kaunlaran ng ating inang bayan!

        ;-)

        Haha! Nakakaaliw ka talaga Comrade Joboniski!

        Teka, napansin ko na atang dalawang beses mo ng sambit yang Liwayliway a?! Nagsubmit ka ng mga tula dun? YIKES!  haha. BTW, 2012 na, wala ng nagbabasa nun! O dun ba nakukuha yung mga posisyong mong pampulitikal?

        At galit ka ata sa panel ng Palangca Award?  Malamang may entry ka, at natalo. Sabagay, yang mga tula mo dito, medyo may pagka-incoherent. haha

       “mga iyan
      matagal ng alam
      ng mga pilipinong nakatira diyan”

      Ows? Totoo ba yan? Kung totoo malamang ang gagawin lang ng mga iyan eh magkibit-balikat at walang pakialam at mag-iinom na lang sa tabi-tabi (number one time killer at gimik ng mga Pinoy).

      Tama ang iba… walang pakialam ang karamihan ng mga Pinoy sa ganyan. Sa mga scientific na mga bagay na ganyan di kayang isipin ng karamihan ng Pinoy at ayaw sa ganyan. Kailangan natin ang tulong ng dayuhan para magawa ito, kaya huwag mo laging ipagyabang na kaya palagi ng Pinoy at madalas di kusang gagawin ng Pinoy iyan. Mapagmalaki ka sa ibang bansa pero tingnan mo naman ang bansa. Nasa resulta ng bansa ang “yardstick” ng “pride” kuno na sinasabi mo.

      Hwag kang magyabang diyan kung wala naman talaga tayong ipagyayabang na maganda at talagang nakakabuti at nakakadagdag sa kaalaman ng tao.

      • http://joboni96.myopenid.com/ joboni96

        hindi ka naglilibot chowchow
        kaya hindi mo alam
        ang maraming kaalaman
        ng mga pilipino
        sa mga liblib na lugar

        resulta yan ng mis education mo
        sa libro ka lang at facebook

        mamundok at magaplaya ka
        paminsan minsan

      Sang ayon ako sa opinyon mo, na dapat ang mga filipino dapat ang naka-discover ng mga bagong spicies na yan kasi nga dito yan sa atin. Kaya lang malabong mangyari yan kasi unang una mga siyantipiko natin ay hindi nakakatanggap ng suporta.Ni ala nga tayong mga hightech na equipment para sa research ng mga makabagong animal o plant species. At ang mga hayop at halaman na yan matagal na matagal na yan andito sa pinas hnd nga nadiscover yan noon, kung hnd ngayon lang nung dumating ang mga foreign scientist saka pa nalaman ng buong mundo na unique ung pinas dahil sa biodiversity natin na maraming yaman dito sa pinas. sila pa nga ang nakatulong satin.kaya para sakin ang corrupt na gobyerno ang dapat sisihin dyan.

        colonized pa rin utak mo
        imbes na magbigay ka
        ng solusyon

        you’re just parroting
        the line of western propaganda
        using the wrong globalization concept
        to ride roughshod
        over less powerful countries

        ang solusyon dyan
        government policy of pilipino led
        expeditions of foreign funded
        flora, fauna etc studies

      • http://profile.yahoo.com/XVMNJHMRWYXAZG4UA7UU5Z4QYI cmiamor

        Western propaganda,  we always complain about it, think who are
        helping us, do we have a choice, what then?  Where is your government policy, look around how many children are in poverty. lucky enough to have a one day meal.  I love my country Philippines, but instead of making excuses about propaganda,  why can’t each one of us start doing something for our country.
        Education is the only way to get out from what you said ” western propaganda”.  Think, if every family in the Philippines who are rich, or can afford to adopt
        a poor kid, support them to have a better education,  this will
        be the key, to show  powerful country, that what they have,  we got  it, “Education”.. just to let you know,  my family have been doing
        this educating children from remote area, through reading.  It’s a big job, but the outcome makes us feel good.

      • http://joboni96.myopenid.com/ joboni96

        congrats!

        don’t forget to document their culture too
        and encourage them to nourish it

        love of country
        won’t let us go astray
        even with the best western education

      • http://profile.yahoo.com/XVMNJHMRWYXAZG4UA7UU5Z4QYI cmiamor

        That’s a good idea, actually I raised my Kids learning and adapting Pilipino culture.  Both of them born and raise abroad, but they love spending time in the Philippines.  There are too many things that we filipino be proud of, specially our family traditions.  

        Thanks for sharing your views about  the country we both care and love.   

        Keep it up joboni96

        I’m with you, Mr Elloreg, you are right, but blaming the corrupt government will not solve the problem, how can we fixed our government
        any idea?  People sell their votes so that they can buy foods to put on their table, this are the problems in our country.  Corruption is a disease of
        our government, how can we cure this ?  I don’t really know.  People may
        not like what I will say, ” I am glad that foreigners [ scientist] are exploring
        the wilderness of the Philippines, finding this  amazing species to share
        the world, and preserving it.  If some of us  will call this colonization then be it.  Beauty should be appreciated not wasted.

    This is something that proves to the world the richness of our country in terms of the rare species that continue to charm scientists from other countries. There are, in fact, still thousands of flora and fauna species not yet identified from below the waters to above ground.

    It really does not matter much to me who has established the identity of the rare species found in our country. What matters to me is that it has been established to be endemic to the Philippines.

    What I am concerned about are the marauding pirates and these ignoramuses board vessels bearing the Chinese banner. They are proving to be the scourge of the world destroying every piece of treasure underwater.

    They should have keep this piece of information.  You know the China man from mainland China will try to get this creature for their insatiable appetite.

    Dapat maging seryoso na tayo sa pagbabantay ng ating kalikasan
    Dapat palawakin ang mga National parks natin kagaya sa
        Sierra Madre
    Maglaan ng masmalawak na mga marine parks din
    Declare na dapat mga national parks mga island groups like
        Babuyan islands, Polilio islands, parts of Tawi-Tawi, mga islands sa
        Surigao, Leyte, Catanduanes, Camiguin, Siquijor, etc
    In short lets declare as many islands and mountains and seas as we can NOW
    Habang wala pa masyado madaming tao sa mga lugar na mga iyon
    At nandoon pa mga native species natin
    DAPAT ITO ANG GAWIN NI PENOY
    PARA MAYROON SIYANG MAGANDANG LEGACY
    PARA MASKI PAPAANO TATAWAGIN SIYANG
    “THE FATHER OF NATIONAL PARKS IN PH” – a GREAT LEGACY FOR HIM

    Dapat itigil na paggamit ng dinamita
    Mga ganitong bagay sana pinaglalaanan ng pasin
    Look at Costa Rica and the Dominican Republic, very pretty places
    Very important ang Zoning

    Oo maganda ang Pilipinas
    Pero, for how long?
    Mamasyal ka, daming basura
    Walang matinong restrooms

    Mga kubol-kubol nasa tabing dagat or nasa ilog na
         A good example sa Wawa dam
    Mga Eyesores
    Sayang na ganda ng Pilipinas kung hindi maaalagaan
    PITIFUL

    Do not show this crab to the Chinese – aagawin na namn nila ang lugar ninyo.

  • manggoding

    This crab is not unusual for us. We have been seeing tha crab since we were kids.
    But Nobody takes notice.
    So, thank you for these scientists that this crab is known to the world.

  • dead_pixel

    Four new species of crab discovered in the biologically diverse Philippines, according to a scientific paper.
    Namely: noyAbnoy, LIE La, Lacierda and aBAD!

      you missed on the fifth, yoself…

      • dead_pixel

        hay nako. apat lang.
        dagdag kanaman!

  • AllaMo

    This is a beautiful picture of a beautiful creature. Please, please keep the habitat and environs of these creatures pristine. Never, ever let the grubby hands of henry sy, and his ilk, get a hold on your paradise. ‘ware of denr and local officials, too.

    We have the richness in biodiversity, we have the people who are experts on the fields of research and science but we don’t have “TECHNOLOGY”. Its is sad to hear that foreigners are the one who are discovering our flora and fauna and even give them names that links the name of the discoverer. Our land and sea are the mecca of all the scientist in the world. They love our nature why can’t we do more than since we are the ones living in this to die for country. Let us act now before everything is gone and taken away from us. We are not being selfish here, in fact we have to give the foreigners the credit because they are the ones who are making the efforts on this richness and make them show to the world that this is found in our country. We should be thankful to them.     

  • http://profile.yahoo.com/XVMNJHMRWYXAZG4UA7UU5Z4QYI cmiamor

    I agree with Mr. Elloreg, we don’t have technology, but  we are also losing the people who are experts on the fields of research and science, medical fields, engineers, teaching fields etc.  they are employed abroad for financial reason, once they are abroad we tend to forget
    the beautiful country that we came from.  Thanks to those foreigners with their technology, our country is being expose to the whole world that the Philippines, a small
    island in south pacific, have this unique species that  most of us did not even bother to appreciate it.  I always think that part of this problem,  the lack of support from our government.  What can we do ?…..that’s the big ???? for us to answer.
