I-Lampreys ifana ne-eels, kepha ayinayo imihlathi futhi ihlobene nama-mixins kune-eels. Kunezinhlobo ezingaphezu kuka-38 zamalambu. Zibonakala kalula ngomlomo wazo omise okofele onamazinyo abukhali.
Incazelo ye-lamprey
Lezi zinhlanzi zifana nezinduna ezinesimo somzimba. Zinemizimba eyindilinga eyindilinga enamehlo amabili ngapha nangapha kwekhanda. ILampreys inamathambo anenqwaba, ayinazo izikali namaphiko ahamba ngababili, kodwa inophiko olulodwa noma ezimbili ezihlanganisiwe zedorsal eseduze nomphetho we-caudal. Imilomo yabo iyisibonelo sephupho elibi: imilomo eyindilinga enemigqa emide yamazinyo abukhali, abheke ngaphakathi. Ukuvuleka kwama-gill angaphandle abonakalayo ohlangothini ngalunye lomzimba eduze kwekhanda.
Izindawo zokuhlala zaseLamprey
Ukukhethwa kwendawo yokuhlala yalezi zidalwa kuncike kumjikelezo wempilo. Ngenkathi zisesigabeni sesibungu, izibani zezibani zihlala emifudlaneni, emachibini nasemifuleni. Zikhetha izindawo ezinodaka oluthambile, lapho izidalwa zicasha khona ezilwaneni ezidla ezinye. Izinhlobo ezindala ezidla izibani zithuthela olwandle oluvulekile, izinhlobo ezingezona ezidlayo zihlala ezindaweni ezihlala amanzi ahlanzekile.
Kukuziphi izifunda lapho kuhlala khona izibani
Isibani se-Chile sitholakala eningizimu yeChile kuphela, kuyilapho isibani se-marsupial Australia sihlala eChile, e-Argentina, eNew Zealand nasezingxenyeni ezithile ze-Australia. Izinhlobo eziningi zitholakala e-Australia, e-USA, eGrisi, eMexico, e-Arctic Circle, e-Italy, eKorea, eJalimane, kwezinye izingxenye zeYurophu nakwamanye amazwe.
Kudliwa ziphi izibani
Ezinhlotsheni ezidla inyama, umthombo wokudla oyinhloko yigazi lezinhlanzi ezahlukahlukene zamanzi ahlanzekile namanzi anosawoti. Ezinye izisulu ze-lamprey:
- i-herring;
- ithrawuthi;
- umbumbulu;
- uhlobo lwenhlanzi;
- oshaka;
- izilwane ezincelisayo zasolwandle.
I-Lampreys imba isisulu sayo isebenzisa inkomishi yokudonsa bese uxubha isikhumba ngamazinyo. Izinhlobo zezinhlanzi ezincane ziyafa ngemuva kokulunywa okubuhlungu kanjalo nokulahleka kwegazi okungapheli.
Lamprey nokuxhumana kwabantu
Ezinye izibani zondla izinhlobo zezinhlanzi zendabuko futhi ziyalimaza futhi zinciphise inani labantu, njenge-high tropical value lake trout. Amalampreys awalimazi nje kuphela impilo yasemanzini, kodwa futhi nomnotho. Ososayensi banciphisa inani elihlaselayo lezibani ngokwethula abesilisa abenziwe inzalo esimisweni semvelo.
Ingabe abantu bathambisa izibani zezibani
Azikho izinhlobo ze-lamprey eziye zasekhaya. ILampreys ngeke zibe yizilwane ezifuywayo ezinhle echibini ngoba kumele zondle izinhlanzi eziphilayo futhi kunzima ukuzinakekela. Izinhlobo ezingezona ezidlayo azihlali isikhathi eside.
Izinhlobo ezahlukene zezibani zinezidingo ezihlukile. Ngemuva kwesigaba sezibungu, izinhlobo ze-anadromous ze-lamprey zisuka emanzini amnandi ziye emanzini anosawoti. Izinhlobo zezinambuzane zihlala ezimweni zamanzi anosawoti, kepha zidinga ukuthuthela emanzini amasha ukuze zikhiqize kabusha. Lokhu kwenza kube nzima ukufuya izibani zamanzi ezindaweni zasemanzini ekhaya. Izinhlobo zamanzi ahlanzekile aziphili isikhathi eside ngemuva kokuguqulwa komzimba.
Izici zokuziphatha kwe-lamprey
Lezi zidalwa azibonisi ukuziphatha okuyinkimbinkimbi. Izinhlobo zezinambuzane zithola umninikhaya bese ziyondla kuze kube yilapho isisulu sifa. Lapho izibani zikulungele ukuzalela, zibuyela emuva lapho zazalelwa khona, zizalele izingane zife. Amalungu ezinhlobo ezingezona ezidla inyama ahlala endaweni yawo yokuzalwa futhi awondli ngemuva kokuguqulwa komzimba. Esikhundleni salokho, zizala ngokushesha futhi zife.
Izala kanjani izibani
Ukuzalela kwenzeka lapho kuzalwa khona izinhlobo eziningi, futhi zonke izibani zizalela ezindaweni ezinamanzi angenasawoti. ILampreys zakha izidleke emadwaleni osebeni lomfula. Abesilisa nabesifazane bahlala ngenhla kwesidleke bese bekhulula amaqanda nesidoda.
Bobabili abazali bazofa kungekudala ngemuva kwesigaba sokuzala. Izibungu zichanyuselwa emaqandeni, zibizwa ngokuthi ama-ammocetes. Bangena odakeni futhi bahlunge okuphakelayo kuze kube yilapho bekulungele ukuvuthwa babe yizibani zabantu abadala.
