Majeremusi, mollusks zitsanzo. ndi nkhono majeremusi chiyani?

Aliyense bwino vuto lililonse molluscs zamiyendo Inayi ndi chipolopolo wokongola. Koma pali mitundu oopsa kwa nyama zimenezi, zimene zimachititsa njira parasitic wa moyo mu thupi la munthu. Tiyenera kupeza amene majeremusi ndi mollusks, ndi zitsanzo zimene takambirana m'nkhaniyi.

ndi nyama zofewa wamphamvu chiyani?

Coelomic mtundu wa nyama, kuphatikizapo nkhono wakutali - yofewa wamphamvu protostomes oimira m'madzi ndi madzi oyera zinyama, ndithudi, pali mitundu kuti bwino anazolowera ndi pa dziko. Kuwonjezera pa zolengedwa zonse izi wokondeka, pali anthu oweta njira parasitic wa moyo, koma iwo kulankhula pambuyo tikuimira moyo ngale wamba.

Nyama zimenezi amaonedwa poyamba bilaterally symmetrical, koma chifukwa kukula m'goli ziwalo munthu wa kosangalatsa osiyana, ndipo pali zachilengedwe asymmetry nkhono.

thupi lawo wapangidwa m'madipatimenti atatu - ndi torso, mutu ndi mapazi aang'ono. Onse ziwalo zina za mollusk opezeka mu thupi, chifukwa ena mwa mitundu pa nthawi, kutaya mutu wanu.

Mantha dongosolo la nyama zofewa wamphamvu tichipeza makungwa anayi - awiri ngo ndi awiri choipidwa.

Izi zokwanira kukhala ndi maganizo amene nkhono.

ndi fyuluta feeders, ngale chiyani? mafotokozedwe

Bivalves zambiri umaimiridwa ndi fyuluta. Moyo, nyama amenewa kawirikawiri lokhazikika, ndipo anatenga dzina chifukwa cha njira chakudya. Ngakhale mu madzi, iwo anadutsa madzimadzi thupi ndi zosefera izo, kusankha zonse muyenera mphamvu ndi kupulumuka. Pakati sefa feeders kudya ndi majeremusi - molluscs zitsanzo za zimene yalongosoledwa momveka bwino mu mabuku a sayansi. Ife kufotokoza iwo mu chaputala osiyana.

Mu mtundu uwu wa alibe miyendo, chifukwa iwo m'malo mwa yekha ndi, imene nyama ndi kupanga gulu lawo pansi, ngati n'koyenera. Pali majeremusi nkhono zitsanzo za zimene zikuonekera mwa anasiya zipangizo aliyense zoyendera. Ichi ndi chifukwa chakuti amakonda zilipodi, kukwaniritsa kokha kudya ndi kubalana.

Bivalve thupi symmetrically ndi zobisika kuseri kwa lakuya chochuluka, amene zaikidwa mbali zonse.

Osati amuna okha omwe angathe ndi anthu moyo parasitic, ndipo pali majeremusi mu nkhono, ndi matenda awo ikuchitika malo apadera Chowona Zanyama. Nthawi zambiri zimachitika kuti mtundu uliwonse wa nyama Aquarium zofewa wamphamvu m'njira anakhudzidwa ndi tizilombo, amene amalenga m'mavuto mwenekaciro wa Aquarium lapansi.

Majeremusi molluscs. Zitsanzo ndi kufotokozera

Osati mollusks onse amakonda moyo osasamala m'thambo la madzi ndi kukwawira pa dziko. Pali anthu amene ali bwino kwambiri mu thupi la munthu wina. Zitsanzo za majeremusi nkhono:

• Mussel mphutsi - amatha gwiritsitsani nsomba ndi kukhalapo kwa iwo monga majeremusi. Nthawi zambiri, iwo mwakachetechete kugona pansi kuyembekezera ena nsembe, monga carp. Pamene nsomba amasambira pafupi mokwanira, nkhono tiziromboti amakhulupirirabe makutu, kumene kupitiriza kukhalapo. Kulikonse Anapitirizabe tiziromboti ayamba pathupi ndipo mwamsanga anapanga kugundana chifukwa chakuti maselo zaminyewa zikuchulukirachulukira. Iwo likukhalira kuti nsombayi kutetezedwa mokwanira ikukoka analenga.
• Nkhono Melanellidae, Stiliferidae, Entoconchidae amakonda kukhazikika mu thupi la echinoderms ndi kuchulukitsa iwo. Koma mitundu ina chabe achotse chakudya ndipo sizibweretsa vuto lililonse.

matenda a majeremusi

Pa akatswiri pano siteji zimayesetsa kuphunzira nkhani ya majeremusi amene amakhala mu thupi la mollusks. Koma si zitsanzo zonse za majeremusi nkhono akhoza kuphunzira bwinobwino. Ichi ndi chifukwa chakuti ena ndi njira zingapo moyo.

The zatsopano kunachitika makamaka pa mitundu monga M. galloprovincialis ndi C. gigas. Kwa deta izi oimira mwakula mu m'galasi ndi podselyayut zamoyo awo parasitic.

Majeremusi, mollusks zitsanzo za zimene takambirana pamwambapa, mwapadera kwa mitundu zimene kuvutika majeremusi.

Thupi la oyisitara chimphona simungathe kudziwa majeremusi monga mphutsi polychaete kapena polychaete chinkhupule Pione vastifica.

Kuzipenya zikusonyeza kuti nkhono anakhudzidwa ndi zamoyo parasitic kukula kwambiri pang'onopang'ono kusiyana ndi nthumwi wathanzi. zipolopolo awo kukhala Chimaona ndi kuswa opanikizika pang'ono.

nkhono otere anakana ndipo si ntchito zogulitsa ndi dilution.

Kodi majeremusi anthu ali oopsa?

Zitsanzo za majeremusi nkhono kuti pali mwayi wokhala kapolo wa ena a iwo. Koma zinthu sizili monga wowopsa monga zingaoneke.

Kodi ngati thupi anapezeka majeremusi nkhono? Zitsanzo za mitundu ina ya mankhwala amasonyeza kuti kudwala izi si zoopsa. Ndi mankhwala pa nthawi yake kwa katswiri mosavuta tichotse iwo ndi kupitiriza kuchirikiza moyo popanda kukhalapo munthu.
