Cishe uke wezwa ngama-annelids, akunjalo? Khumbula nje izindandatho, okuyilapho igama lale phylum yombuso wezilwane zaqhamuka khona. Ama-annelids ayiqembu elihluke kakhulu, kunjalo izinhlobo ezingaphezu kwezingu-1300, phakathi kwazo sithola izilwane zasemhlabeni, zasolwandle kanye namanzi angenasawoti.
Ama-annelids aziwa kakhulu yizibungu zomhlaba, izinhlobo ezibalulekile zokuphinda zisetshenziswe izinto eziphilayo futhi ezisemqoka kuyo yonke imvelo. Kepha leli qembu lifaka nezinhlobo ezahlukahlukene njengezimbungulu noma amagundane asolwandle. Ufuna ukwazi okwengeziwe ngabo? Kule ndatshana yePeritoAnimal, sikutshele konke odinga ukukwazi ngakho izinhlobo zama-annelids, amagama abo, izibonelo kanye nezimpawu zabo. Ukufunda okuhle!
Izici zama-annelids
Uma sikhuluma ngama-annelids sisheshe sicabange nge- izibungu, kwesokudla? Bangabamele abaziwa kakhulu bale phylum. Njengoba sesishilo, iqembu lama-annelids lihluke kakhulu. Futhi yize kunezici ezithile eziyisisekelo nezakhi zofuzo, banokufana okuncane. Noma kunjalo, singasho ezimbalwa. ukufana kwe-anatomical.
- Inhloko: ngaphambili noma ekhanda, kukhona izitho zobuchopho nezinzwa. Phakathi kwalezi zitho kukhona imitshina yokukhanya, amakhemikhali nendawo yesikhala.
- Umlomo: ikhanda lilandelwa yisifunda esinezigaba ezinde, okungukuthi, sehlukaniswe saba ngama-subunits amaningi aphindayo. Engxenyeni yokuqala yalezi zingxenye kunomlomo. Konke okunye kuyafana noma kufana kakhulu.
- Ingquza: Okokugcina, banengxenye yokugcina eyaziwa ngokuthi i-pygidium, lapho ungabona khona indunu.
Njengokulangazelela, sishiya esinye isihloko sikaPeritoIzilwane ngezilwane ezihlangabezana noguquko. Ubuvele ubazi?
Izinhlobo zezilwane ezisuswa minyaka yonke
Kunezinhlobo ezahlukahlukene kakhulu zama-annelids. Zingama-polychaetes, ama-oligochaetes nama-hirudinomorphs. Ungakhathazeki ngamagama, sizokukhombisa ukuthi ngabe yisiphi esinye salezi zilwane. Sizophinda futhi sithathe leli thuba ukukhuluma nge ukudla okwahlukahlukene kwama-annelids.
Izibonelo zezilwane ezisuswa ngonyaka
- Ulwandle ulwandle (Umndeni wakwa-Aphroditidae)
- isibungu sokususa izintuli (Umndeni wakwaSabellidae)
- izibungu zomhlaba (oda i-Crassiclitellata)
- izibungu ezibomvu (I-Eisenia spp.)
- I-Leech (Hirudine)
- Isibunguumbumbulu)
- I-Nereis (I-Nereis funchalensis)
- I-Tubifex (I-Tubifex Tubifex)
- I-Peripatus (Udeonychophora)
1. Ama-Polychaete annelids
Ama-Polychaetes (ikilasi lePolychaeta) yiwo ama-annelids akudala kakhulu. Igama lalo lisho "ama-quetas amaningi" futhi libhekisele ohlotsheni lwezinwele ezihamba phambili abazisebenzisayo ukubhukuda nokuhamba.
Ngaphakathi kwaleli qembu singathola amagundane olwandle (Umndeni wakwa-Aphroditidae). Lezi zilwane ezincane zihlala zingcwatshwe ngaphansi kwesihlabathi ngaphansi kolwandle, yize zishiya ingxenye yemizimba yazo ivezwe ukuphefumula nokuphakela. Ukudla kwabo kususelwa ekubambeni izikelemu zomhlaba kanye ne-shellfish.
Amanye ama-polychaete annelids adla izinhlayiya zokudla ezintanta emanzini olwandle. Ngalokhu, bakhiqiza imisinga ngenxa yochungechunge lwezintambo ezikhona emakhanda abo. Wonke umzimba uvulekile futhi uhlala ngaphakathi kweshubhu abazenzela ngokwabo nge-calcium carbonate. esikhuluma ngakho izimpethu (Umndeni wakwaSabellidae).
2. Oligochaete annelids
Ama-Oligochaetes ayiqembu lama-annelids ngokuvamile eyaziwa ngokuthi "izibungu". Amakhosi akhe mancane kakhulu noma awabonakali.
Leli qembu lifaka phakathi izibungu zomhlaba (oda i-Crassiclitellata) namaqembu amaningi we izibungu zamanzi, womabili amanzi ahlanzekile nosawoti.
Izikelemu ezibomvu (I-Eisenia spp.) iyiqembu lezikelemu ezisetshenziswa kakhulu kwezolimo ukwenza umquba. Lokhu kungenxa yesivinini sayo esikhulu sokuguqula izinto eziphilayo (izinsalela zezitshalo, indle, njll.) Zibe inhlabathi evundile.
3. AmaHeludine annelids
IHirudinea (ikilasi iHirudinea) yiqembu lama-annelids afaka phakathi izinhlobo ezingaphezu kuka-500, iningi lawo kungamanzi ahlanzekile. Phakathi kwazo singathola izidalwa ezingenamgogodla nezinambuzane eziningi.
Kuleli qembu kukhona ezinye izimuncagazi owaziwa: izinambuzane. La ma-annelids adla egazini lezinye izilwane. Ngalokhu, banenkomishi yokudonsa ngaphakathi lapho banamathela khona kumphathi. Isibonelo salawa ma-annelids yizinhlobo zohlobo Ozobranchus, ezondla kuphela ngegazi lofudu.
Ukukhiqizwa kabusha kwama-annelids
Ukukhiqizwa kabusha kwama-annelids kuyinkimbinkimbi kakhulu futhi kwehlukile eqenjini ngalinye, futhi naphakathi kohlobo ngalunye. Eqinisweni, ayihlali ingokobulili ngaso sonke isikhathi, kepha futhi ingahle ibe nge-asexual. Kodwa-ke, ukuze kube lula, ake sichaze nje ukukhiqizwa ngokocansi kweqembu ngalinye.
Ama-annelids ePolychaete
Ama-annelids ePolychaete yiwo izilwane dioecious, okungukuthi, abantu ngabanye bangaba owesilisa noma owesifazane. Abesilisa bakhiqiza isidoda bese abesifazane bekhiqiza amaqanda. Zombili lezi zinhlobo zamageyimu ziyaphuma futhi inyunyana yazo zombili (ukukhulelwa) kwenzeka emanzini. Kwakhiwa kanjalo umbungu ozoveza umuntu omusha.
Le ndlela yokuzala ifana kakhulu neyamakhorali. Thola okuningi mayelana nalezi zidalwa ezimangalisayo ezinhlotsheni zamakhorali.
ama-oligochaete annelids
Izikelemu (oligochetes) kukhona i-hermaphrodites, okungukuthi, umuntu ofanayo unezinhlelo zokuzala zabesilisa nabesifazane. Kodwa-ke, umuntu akakwazi ukuvundisa yena, kunjalo njalo kwakudingeka ama-annelid amabili. Umuntu usebenza njengendoda bese unikela ngesidoda. Omunye udlala indawo yabesifazane bese esabalalisa iqanda.
Ngesikhathi sokulingisa, ama-oligochaetes amabili azimisa ngokwawo zibheke ezinhlangothini eziphambene. Ngalesi sikhathi, abesifazane nabesilisa baxosha ama-gametes abo. Lokhu kuqoqwa ngumfece owakhelwa insikazi phambilini ngenxa yendlala ebizwa ngokuthi i-clitoris. Kukukhokho lapho ukuhlangana kweqanda nesidoda kwenzeka, okungukuthi, ukukhulelwa. Bese kuthi ekugcineni umfece uhlukane nowesifazane. I-annelid encane izophuma kuyo.
Ama-annelids we-Hirudinal
Ama-annelids we-Hirudinal nawo izilwane hermaphrodite. Ukukhulelwa, noma kunjalo, kunjalo kwangaphakathi. Umuntu osebenza njengowesilisa ufaka ipipi lakhe kowesifazane bese ekhipha isidoda kuye.
