Lampreys amafanana ndi ma eel, koma alibe nsagwada ndipo amalumikizana ndi zosakaniza osati ma eel. Pali mitundu yoposa 38 ya nyali. Amadziwika mosavuta ndi kamwa yawo yoboola pakati yopyapyola ndi mano akuthwa.
Kufotokozera kwa lamprey
Nsombazi ndizofanana ndi ma eel mu mawonekedwe amthupi. Amatambasula, matupi ozungulira ndi maso mbali zonse ziwiri za mutu. Lampreys ali ndi mafupa a cartilaginous, alibe masikelo kapena zipsepse zolimbitsa thupi, koma ali ndi zipsepse zakuthambo chimodzi kapena ziwiri zazitali zomwe zili pafupi ndi chimbudzi. Pakamwa pawo ndi gawo lotopetsa: milomo yozungulira yokhala ndi mizere yolunjika ya mano akuthwa mkati. Zotsegula zisanu ndi ziwiri zakunja kwa gill zimawoneka mbali zonse za thupi, pafupi ndi mutu.
Malo okhala Lamprey
Kusankha malo okhala zamoyozi kumadalira kayendedwe ka moyo. Ali m'kati mwa mphutsi, nyali zimakhala m'mitsinje, nyanja ndi mitsinje. Amakonda malo okhala ndi matope ofewa ofewa, momwe nyama zimabisala kuzinyama. Mitundu yayikulu yamphesa yodya nyali imasamukira kunyanja yotseguka, mitundu yosadya nyama imakhalabe m'malo okhala madzi oyera.
M'madera omwe nyali zimakhala
Nyali zaku Chile zimapezeka kumwera chakumwera kwa Chile, pomwe nyali zaku Australia zimakhala ku Chile, Argentina, New Zealand ndi madera ena a Australia. Mitundu yambiri imapezeka ku Australia, USA, Greece, Mexico, Arctic Circle, Italy, Korea, Germany, madera ena aku Europe ndi mayiko ena.
Zomwe nyali zimadya
Kwa nyama zodya nyama, gwero lalikulu la chakudya ndi magazi a nsomba zamadzi amchere zamchere komanso zamchere zamchere. Anthu ena omwe anakhudzidwa ndi nyali:
- hering'i;
- nsomba ya trauti;
- nsomba ya makerele;
- Salimoni;
- nsombazi;
- Nyama zam'madzi.
Lampreys amakumba nyama yawo pogwiritsa ntchito chikho chokoka ndikutsuka khungu ndi mano awo. Tinsomba tating'onoting'ono timafa titaluma kwambiri komanso kutaya magazi nthawi zonse.
Lamprey ndi kuyanjana kwaumunthu
Zina mwa nyali zimadyetsa mitundu ya nsomba zachilengedwe ndipo zimawononga komanso kuchepa kwa anthu, monga nsomba zam'madzi zamtengo wapatali. Lampreys sichiwononga zamoyo zam'madzi zokha, komanso chuma. Asayansi amachepetsa kuchuluka kwa nyali poyambitsa amuna oletsedwa m'chilengedwe.
Kodi anthu amawongolera nyali
Palibe mitundu yamtundu wa nyali yomwe yakhala ikuweta. Lampreys si ziweto zabwino mu dziwe chifukwa amayenera kudyetsa nsomba zamoyo ndipo ndizovuta kusamalira. Mitundu yosadya yomwe siikhala nthawi yayitali.
Mitundu yosiyanasiyana ya nyali ili ndi zosowa zosiyanasiyana. Pambuyo pa mphutsi, mitundu ya nyerere ya anadromous imachoka pamadzi amchere kupita kumadzi amchere. Mitundu yodzikongoletsa imakhala mumadzi amchere, koma amafunika kupita kumadzi abwino kuti aberekane. Izi zimapangitsa kuti zikhale zovuta kubzala nyali m'madzi am'madzi kunyumba. Mitundu yamadzi amchere simakhala moyo patadutsa nthawi yayitali.
Makhalidwe a lamprey
Zamoyo izi sizisonyeza machitidwe ovuta. Mitundu yonyenyerera imapeza wolandila ndikuyidyetsa mpaka womwalirayo amwalira. Nyali zikakhala kuti zakonzeka kuswana, zimasamukira kumalo komwe zidabadwira, zimabala ana ndikufa. Mamembala amitundu yosadya nyama amakhalabe m'malo awo obadwira ndipo samadyetsa pambuyo poti masinthidwe amthupi. M'malo mwake, zimaswana nthawi yomweyo ndikufa.
Momwe nyali zimakhalira
Kuberekana kumachitika komwe nyama zimabadwira, ndipo nyali zonse zimaswanirana m'malo amadzi oyera. Lampreys amamanga zisa pamiyala ya m'mbali mwa mtsinje. Amuna ndi akazi amakhala pamwamba pa chisa ndikutulutsa mazira ndi umuna.
Makolo onse amwalira atangobereka kumene. Mphutsi zimaswa kuchokera m'mazira, zimatchedwa ammocetes. Amaboola m'matope ndikusefa chakudya mpaka atakhala okonzeka kukhazikika m'miyeso yayikulu.
