Izimbaza ziyi-mollusk enegobolondo eliqinile elinama-valve amabili. Zihlala emhlabeni wonke, kusukela e-Arctic kuya e-Antarctic, futhi zihlala emanzini. Iningi lihlala emanzini olwandle, aze afike kumamitha ayi-11,000. Kodwa kukhona nezimbaza emanzini anosawoti nahlanzekile, okungukuthi emachibini nasemifuleni.
Kunezinhlobo ezingaba ngu-10,000 zamagobolondo asolwandle. Izinhlobo eziphindwe kabili sezivele zashabalala. Kubo, kukhona izinsalela kuphela.
Ibukeka kanjani imizimba yembaza?
Isitsha singaphandle. Iqukethe izingxenye ezimbili. Axhunywe ngohlobo lwehinji. Embazeni, le hinge ibizwa ngokuthi “isikhiya”. Amagobolondo aqinile futhi aqukethe umcako omningi namanye amaminerali. Ngaphakathi imbozwe unina weparele.
Ijazi livale ikhanda namathumbu. Ezinye izimbaza zicishe zivaleke futhi zinezimbobo ezintathu kuphela: amanzi anokudla nomoya-mpilo angena ngembobo eyodwa, futhi udoti uphuma namanzi kwenye. Isivulo sesithathu esonyawo.
Ikhanda liye lahlehla ngesikhathi sokuziphendukela kwemvelo. Ulimi lokudlwengula nalo selucishe lwaphela nya. Emaphethelweni omlomo kunezinzwa ezinezinkophe, eziphusha izingcezu ezincane zokudla zibheke lapho kuvuleke khona umlomo.
Ezinhlotsheni eziningi zezimbaza, unyawo luhlehle kakhulu. Ukwenza lokhu, ikhiqiza uhlobo lweglue ezimbazeni ezincane, ezifana ne-slime eminenke. Ngale ngcina, imbaza ingakwazi ukuzinamathisela phansi noma kwenye imbaza futhi iphinde ihlukane futhi.
Zidla kanjani izimbaza?
Izimbaza zimunca amanzi. Basefa lokhu emathunjini njengezinhlanzi. Ngokwenza kanjalo, abagcini nje ukukhipha umoya-mpilo emanzini, kodwa futhi ne-plankton. Ukudla kwabo lokhu. Basebenzisa imizwa ukuphusha ipulangwe emlonyeni wabo.
Ngakho izimbaza eziningi zimunca amanzi amaningi futhi ziwakhulule futhi. Nokho, lokhu kusho nokuthi inani elikhulu likashevu ophuma emanzini lingena emizimbeni yabo. Lokhu akuyingozi kuphela ezimbazeni ngokwazo, kodwa nakubantu abadla izimbaza.
Kukhona namagobolondo olwandle. Bamba izinkuni badle ngazo. Bangakwazi ukucekela phansi imikhumbi yonke futhi ngenxa yalokho abantu bayesaba kakhulu.
Zimbalwa kakhulu izinhlobo zezimbaza ezingabazingeli. Balandela izinkalankala ezincane. Bawumunca kanye nomfudlana wamanzi futhi bawugaye.
Ama-clams aphila futhi azalane kanjani?
Izinhlobo eziningi zezimbaza zinezinduna nezinsikazi. Azihlangani ukuze zizalane. Abesilisa badedela ama-sperm cell abo emanzini, kanti abesifazane amaqanda abo. Lokhu kungenzeka ngoba izimbaza zihlala zisondelene.
Ama-sperm cells namaqanda amaqanda azitholana ngokwawo. Ngemva kokukhulelwa, izibungu ziyakhula kuwo. Lena indlela yokuphila phakathi kweqanda elivundisiwe kanye negobolondo elifanele.
Izimbaza ezincane zingahamba ngezindlela ezihlukahlukene. Iningi lipheqa amagobolondo avuleke futhi avaleke. Lokhu kungafaniswa nokubhakuzisa amaphiko enyoni. Abanye belula izinyawo zabo, bazinamathisele phansi bese bedonsa imizimba yabo. Bese bekhulula ingcina bese belula unyawo futhi. Uhlobo lwesithathu lumunca amanzi futhi luwaxoshe ngokushesha. Lokhu kubangela ukunyakaza ngokuvumelana nesimiso se-rocket.
Ekupheleni kwenkathi yokuthomba, izimbaza zifuna indawo efanelekayo yokunamathela kuzo. Bachitha impilo yabo yabantu abadala lapho. Ikakhulukazi izimbaza nama-oyster zakha amakoloni. Kodwa nezinye izinhlobo zenza lokho. Kulokhu, igobolondo elilodwa linamathela kwelinye.
Uyini umama weparele?
Ingaphakathi lamagobolondo embaza amaningi likhanya ngemibala ehlukahlukene. Lolu ungqimba lubizwa ngokuthi unina weparele. Impahla ibizwa nangokuthi unina weparele. Lokhu empeleni kusho ukuthi le nto ingumama wamaparele.
Umama-we-pearl ubelokhu ebhekwa njengebalulekile. Ubucwebe bomama-we-pearl bukhona kusukela nge-Stone Age. Ngisho nangaphambi kokuba uColumbus eze eMelika, amagobolondo ayenencazelo efanayo neyemali yethu. Ngakho babeyimali yangempela yezwe.
Ubucwebe bomama weparele butholakala emhlabeni wonke. Esikhathini esidlule, izinkinobho zomama weparele zenziwa futhi zisetshenziswe kumahembe nama-blouses. Kusenezinsimbi zomculo ezibizayo, isibonelo entanyeni yeziginci, ukuze umculi azitholele indlela.
Amaparele akhiwa kanjani?
Amaparele ayindilinga ayindilinga noma izigaxa ezenziwe ngempahla efana kakhulu nomama-weparele. Kwakucatshangwa ukuthi imbaza yayiyisebenzisela ukugoqa izinhlamvu zesihlabathi ezazingena kuso, zingabi nangozi.
Namuhla, ososayensi bacabanga ukuthi ama-parasite angafudukela embazeni. Lezi izidalwa ezincane ezifuna ukudla imbaza ngaphakathi. Imbaza izivikela ngokusonga lezi zinambuzane ngempahla yeparele. Yile ndlela amaparele enziwa ngayo.
Abantu bawasebenzisa kanjani amagobolondo asolwandle?
Indlela elula ukuqoqa amagobolondo emanzini afika emadolweni. Lapho amagagasi aphansi, zivame nokulala phezulu. Kungenjalo, kufanele uzicwilisele.
Ikakhulu izimbaza ziyadliwa. Ukudla kuyefana nenhlanzi. Abantu emhlabeni wonke basebenzisa lo mthombo wokudla ngasolwandle. Kodwa-ke, izindawo ziyashesha ukuchithwa ngoba izimbaza zikhula kancane kakhulu.
Ezinye izinhlobo zezimbaza zilungele ukulima, ikakhulukazi izimbaza, ukhwathu, nezimbaza. Lezi zimbaza ziphinde ziphile eduze kwemvelo futhi zakha imibhede yezimbaza. Abantu bazalela izimbaza ezinjalo ezindaweni ezivalekile ezifanele noma kuma-trellises. Ngemva kokuvuna, baya emakethe.
Noma ubani othenga iparele namuhla ngokuvamile uthola iparele elikhulisiwe. Izinhlobo ezithile kuphela zezimbaza ezifanele lokhu. Kufanele uvule igobolondo bese ukhipha ingxenye ethile yengubo kuyo. Izingcezu zayo ezincane zibe sezitshalwa kwezinye izimbaza. Iparele libe seliyizungezile. Kuye ngohlobo lwembaza, lokhu kuthatha izinyanga ezimbalwa kuya eminyakeni embalwa.
Uyaluzwa ulwandle lugijima phakathi kwamagobolondo?
Uma ubambe igobolondo lembaza elingenalutho endlebeni yakho, uzozwa umsindo oheyizayo. Ungaphinda urekhode lo msindo ngombhobho. Ngakho akuwona umcabango, kodwa futhi akuwona umsindo wolwandle.
Igobolondo le-conch elingenalutho liqukethe umoya ofana necilongo noma isiginci. Kuye ngefomu, lo moya unokudlidliza okuwufanela kangcono. Lokhu kudlidliza sikuzwa njengomsindo.
Igobolondo lezimbaza licosha yonke imisindo evela kulo ngaphandle. Imunca futhi igcine ukudlidliza okufaneleka kangcono isimo sayo sangaphakathi. Lokho sikuzwa njengomsindo lapho sibambe igobolondo le-conch ezindlebeni zethu. Sizwa cishe umsindo ofanayo egobolondweni elingenalutho lomnenke wasolwandle, mhlawumbe ngokucace nakakhulu. Kodwa ngisho nenkomishi noma inkomishi endlebeni, kunomsindo ofanayo.
