Ama-parasite-mollusks: imizekelo. Ziziphi ii-shellfish izidumbu?

Wonke umntu uyazi i-mollusks engenanto engenanto engenalo igobolondo elihle. Kodwa kukho iintlobo ezinobungozi zezi zilwanyana ezikhokelela kwimpilo yomzimba emzimbeni womntu. Sifanele sithole ukuba ngubani i-shellfish i-parasites, imizekelo yayo esiya kuyiqwalasela kweli nqaku.

Ziziphi izilwanyana ezixhambileyo?

Uhlobo olumkelekileyo lwezilwanyana, phakathi kwazo ezizimeleyo kunye neellusks - zingabonakali abameli bezilwanyana zasolwandle kunye namanzi aphelileyo, zikho iintlobo ezizimeleyo emhlabeni. Ukongezelela kuzo zonke izidalwa ezithandekayo, zikhona ezo zikhokelela ngendlela yokuphila, kodwa siya kuthetha ngazo emva kokuba sicinge ngendlela yokuphila kwee-mollusks eziqhelekileyo.

Ezi zi lwanyana ziqale zithathwa njengama-symmetric symmetric, kodwa ngenxa yokukhula okungalingani kwamalungu ahlukeneyo, amaqela ahlukeneyo ayafuduswa, kwaye i-asymmetry yemvelo ye-mollusks ivela.

Umzimba wabo unamalungu amathathu-i-trunk, intloko kunye nemilenze emincinci. Zonke iinjongo eziphambili ze-mollusk zihlala kwisiqu, ngoko ke ezinye zezilwanyana zilahlekelwa yintloko yazo ekugqibeleni.

Inkqubo yeentlanzi zezilwanyana ezingenasiphelo ziqukethe izilwanyana ezine-i-pedal ezimbini kunye ne-visceral ezimbini.

Oku kwanele ukuba ube nombono wokuthi ngubani i-mollusks.

Ziziphi i-shellfish? Inkcazelo

Iimbambano ezixhatshazwayo zihlala zimelelwa ngabafaki-mafutha. Indlela yokuphila yezilwanyana ezinjalo, njengommiselo, ayinakususwa, kwaye negama abayifumene ngenxa yokutya. Ukuba emanzini, badlula emzimbeni wabo kwaye bawuhluze, ukhetha okubaluleke kakhulu kwondlo kunye nokuphila. Phakathi kwabafaki-mafayili kukho iipasasites - i-mollusks, imizekelo yaloo nto ichazwe ngokukhawuleza kwiincwadi zezikolo kwi-biology. Sibachazela kwisahluko esahlukileyo.

Le ntlobo ayinayo imilenze, kuba ithathelwe indawo yedwa, apho izilwanyana zenza ukuhamba kwazo emhlabeni, ukuba kuyimfuneko. Kukho i-mollusks ye-parasitic, imizekelo ebonisa ukungabikho ngokupheleleyo kwezixhobo zokuhamba. Oku kubangelwa kukuba banqwenela ubukho bokuhlala, benelisekile kuphela ngokutya nokuveliswa kokutya.

Umzimba we-bivalves ulingana kwaye ufihliwe emva kwegobolondo ekhuselekileyo enamathele kumabini omabini.

Abahlali kuphela abanokuba ngamaxhoba okuphila, kodwa kukho iipasasia ngaphakathi kwe-mollusks, kwaye ukuxilongwa kwabo kuqhutyelwa kwiziko elithile lezilwanyana. Ngokuqhelekileyo kwenzeka ukuba abameli be-aquarium yezilwanyana ezincinci zichaphazeleke ngandlela-thile, ezidala ingxaki enkulu kumnini we-aquarium.

Iipasasites-mollusks. Imizekelo kunye nenkcazo

Akunabo bonke i-molluscs enqwenela ukuhlala ngokungakhathali emanzini kunye nokuhamba. Kukho abo bakhululekile kumzimba womnye umntu. Imizekelo yee-parasites ze-mollusc:

• I-Larvae yabantu abangenabuthathaka bayakwazi ukubambelela kwiintlanzi kwaye zikhona kuzo, njengama-parasites. Ngokuqhelekileyo balala ngokucace ngezantsi ngokulindela uhlobo oluthile lombingelelo, umzekelo, i-carp. Xa intlanzi ihamba ngokukhawuleza, i-parasite inamathele kwiigill, apho iqhubeka khona. Indawo apho iintonga ze-parasite ziqala ukukhula ngamandla kwaye ngokukhawuleza, i-tubercle ethile ibunjwe ngenxa yokuba iiseli ze-epithelial zanda. Kuvela ukuba i-mollusc ikhuselwe ngokupheleleyo kwi-sprawl eye yaphuhliswa.
• I-Shellfish Melanellidae, i-Stiliferidae, i-Entoconchidae ikhetha ukuhlalisa umzimba we-echinoderms kwaye iphindwe kubo. Kodwa ezinye iintlobo zithatha ukutya kwazo kwaye musa ukulimaza.

Ukuxilongwa kwezidumbu

Kulo nqanaba lwanje, izazi zezinto eziphilayo zibandakanya ngamandla ekufundeni izidumbu ezihlala emzimbeni we-mollusks. Kodwa ayikho yonke imimiselo ye-mollusc parasites inokufundiswa ngokupheleleyo. Oku kubangelwa kukuba abanye abameli babakhokela ngeendlela ezininzi zobomi.

Iingcaphephe zenziwa ngokubanzi kwiintlobo ezinjengoMel galloprovincialis kunye noCgigas. Kule datha, abameli bahlonywa phantsi kweemeko zokuzibandakanya kwaye zihlala ziphila zizidalwa zendalo.

Ama-mollusks ama-parasitic, imizekelo esiyihlolisayo ngasentla, ihluke ngokusuka kwiintlobo eziba ngamaxhoba ezidumbu.

Emzimbeni we-oyster enkulu, kunokwenzeka ukuba ufumane iipasasites ezifana ne-polychaete imbongolo okanye i-polychaetes, isiponji Pione vastifica.

Imiboniso ibonisa ukuba ii-oyster ezichaphazelekayo zizidalwa zendalo zikhula ngokuthe ngcembe kunabameli abasempilweni. Iigobolondo zazo ziba zikhuni kwaye ziphule ngokuncinci.

Ama-mollusks anjalo anqatshelwe kwaye ayisebenzisi ukuthengiswa nokuzalisa.

Ngaba izidumbu eziyingozi kumzimba womntu?

Imizekelo ye-parasites ye-mollusk ibonisa ukuba kukho amathuba amakhulu okuba lixhoba labanye. Kodwa yonke into ayisoyikiyo njengoko kubonakala ngathi.

Kuthiwani ukuba kukho i-mollusks ye-parasitic emzimbeni? Imizekelo yezinye iintlobo zonyango zibonisa ukuba le ntsholongwane ayiyonto. Ngokufikelela ngexesha elifanelekileyo kwiinkcukacha, unokukwazi ukubalahleka lula kwaye uqhubeke nobomi ngaphandle kokugcina ubukho bomntu.
