Hydroid (jellyfish): isakhiwo, imifanekiso, izitho zomzimba

A ezihlukahlukene izilwane zasolwandle kanye, ukuthi ngeke ngokushesha isintu siyokwazi ukufunda kubo ewonke. Nokho, ngisho isikhathi eside futhi Aquatics ongaphandle owaziwa ungakwazi kusimangaze izici kuze kube manje ezingabonwayo. Ngokwesibonelo, kwatholakala ukuthi hydroid ezivamile (jellyfish) akasoze afa zokuguga. Kubonakala sengathi lokhu kwesilwane eyaziwa emhlabeni, possesses ukungafi.

morphology Jikelele

Hydroid jellyfish kungokwalabo uhlobo coelenterate, ikilasi hydroid. Lawa izihlobo abakhulu polyp, kodwa more xaka. Mhlawumbe wonke umuntu bazi kahle ukuthi izinto indlela ngifane jellyfish - amasondo esobala, izambulela noma izinsimbi. Zingase abe constriction okwesongo phakathi umzimba noma ngisho ukuba ukuma ibhola. Medusa ayinakho umlomo, kodwa kukhona lezi ngomlomo. Abanye abantu ngisho kancane pink ihambe phezu emaphethelweni.

Isimiso sokugaya ukudla bungene se-jellyfish saba libizwa gastrovascular. Sinenkosi esiswini, okuvela kulo ukuze azungeze umzimba suka isiteshi sesine osabalalayo, ithela kulo isiteshi ezivamile annular.

Tentacles nge amaseli esintinyelayo esisogwini efanayo isambulela umzimba imiphetho, bakhonza bobabili isitho lemizwa touch, futhi ithuluzi okuzingela. Uhlaka lwamathambo sishoda, kodwa kukhona imisipha ezenza jellyfish uhamba. Ezinye zenyathi ihambe futhi uguqulwe statolith statocysts - izinhlaka zilingana. Indlela motion lincike ohlotsheni, ukuze elingelakwaJuda a hydroid ethize (jellyfish). Lokuzaliswa nokwakha kwabo ngeke nazo ziyehluka.

Ngethukile uhlelo hydromedusae inethiwekhi amangqamuzana kukhona emaphethelweni ifomu isambulela amasongo amabili: ukukhokhiswa zangaphandle ebucayi, yangaphakathi - ukunyakaza. Abanye babe amehlo ukukhanya-sensitive, esisogwini emagcekeni ihambe.

Izinhlobo jellyfish hydroid

Subclasses ukuthi best ukulinganisela izitho - statocysts ngokuthi trahilidami. Athuthela ngokusebenzisa ukuxoshwa amanzi kusukela isambulela. Baphinde babe useyili - a neziqu okwesongo ohlangothini engaphakathi olugcwele okukhiphayo kusukela ingaphakathi lomzimba. Uyanezela isivinini jellyfish lapho ushayela.

Leptolidy bancishwa statocyst, noma siguqulelwa umfuma ekhethekile, ngaphakathi okungase kube khona eyodwa noma ngaphezulu statoliths. Athuthela emanzini akuyona esisheshayo ngakho ngenxa isambulela yabo ayikwazi ukwenziwa futhi ngokuvamile okukhulu.

Kusese hydrocorals medusoid, kodwa zifana ampofu futhi kancane ukuze jellyfish abavamile.

Chondrophores bahlala amakoloni enkulu. Ingxenye polyp yabo vypochkovyvaet jellyfish ezihlala bebodwa.

Siphonophores - hydroid (jellyfish), isakhiwo okuyinto engavamile futhi ezithakazelisayo. Kuyinto lonke ikoloni, lapho ngamunye wenza yendima yayo ekuqhubeleni ukusebenza wonke umzimba. Ngaphandle, kubukeka sengathi lokhu: phezu ibhamuza esikhulu elintantayo ngesimo isikebhe. Anakho nezindlala ezikhiqiza igesi esisiza ukuba untante kuya phezulu. Uma siphonophores ufuna ukubuyela emuva ezijulile - ke nje ephumula umzimba wakho kwemisipha eduze. Ngaphansi bubble ku isiqu nezinye zitholakala ngesimo amancane izinsimbi jellyfish ukubhukuda, balandela gastrozoidy (noma abazingeli), khona-ke gonofory ogama njongo - ukuzala.

ukukhiqizwa kabusha

Hydroid jellyfish ungowesilisa noma owesifazane. Ukuvundisa ngokuvamile kwenzeka ngaphandle, kunokuba ngaphakathi emzimbeni wensikazi sika. Gonads jellyfish elise noma ngomlomo yi-ectoderm lezi, noma yi-ectoderm isambulela ngaphansi iziteshi osabalalayo.

ubulili amaseli Mature bangaphandle kumiswa amakhefu ekhethekile. Ngokulandelayo, ngaleso sikhatsi bafundza bacala ukuzobhidliza, ukwakha blastula, ingxenye lapho amaseli bese retracts ngaphakathi. Umphumela kuyinto endoderm. Ngokuhamba ukuqhubeka kwenani elithile amaseli ayo lukhumuzeka ukwakha umgodi. Kuyinto kulesigaba neqanda avundiswa, isibungu iba planuly ke luhlala phansi, lapho ibe gidropolip. Kuyathakazelisa ukuthi iqala iveze imiqumbe polyp entsha bese meduzok encane. Khona-ke ingane yakho ikhula futhi ekuthuthukiseni eziphilayo njengochwepheshe abazimele. Kwezinye zezintaka planul kwakhiwa medusae kuphela.

Ukuguquguquka sokukhulelwa kuxhomeke kulokho uhlobo, zinhlobo noma zenyathi fanele hydroid (jellyfish). Physiology nasekuvezeni izithombo zaso ezintsha, kanye isakhiwo, ezahlukene.

Bahlalaphi

Iningi zezinto eziphilayo bahlala olwandle, lingandile kangako zingabantu emanzini angenawo usawoti. Found kubo ukuba eYurophu, eMelika, e-Afrika, e-Asia nase-Australia. Abakwazi avele abamba ukushisa amathangi, kanye amadamu yokufakelwa. Baphi polyp kanye hydroids njengoba isihloko emhlabeni, kuze isayensi alucacile.

Siphonophores, chondrophores, hydrocorals, trahilidy ukuphila kuphela kolwandle. leptolid kuphela ingatholakala amanzi ahlanzekile. Kodwa kuyingozi nabameleli phakathi kwabo incane kakhulu ukwedlula olwandle.

Ngamunye zama-jellyfish kuthatha kwendawo ezihlala kuyo, isibonelo, noma yimuphi ulwandle ethile, ichibi noma bay. It kungenziwa landiswa kuphela ukuhamba emanzini, ikakhulukazi jellyfish saba awuthumbe edlulela emasimini amasha. Ezinye njengebandla abandayo, kuyilapho abanye - ukushisa. Abakwazi ukuphila eduze kwamanzi noma ukujula. Lesi sakamuva akuyona eziyizici ukufuduka, futhi ukwenze kuqala ngakho ukuze uthole ukudla, kusale usuku ezijulile kukholamu amanzi, futhi ebusuku ukugibela phezulu futhi.

indlela yokuphila

Isizukulwane kuqala ngibone umjikelezo wokuphila kwe hydroid - a polyp. Okwesibili - jellyfish hydroid enomzimba esobala. Ngenxa yalokho-ke yenza ukuthuthukiswa mesogloea eqinile. It gelled futhi luqukethe amanzi. Kungenxa yokuthi kunzima ukubona jellyfish saba emanzini. Hydroids ngenxa kokuhlukana ka ukukhiqizwa futhi khona izizukulwane ezahlukene ukukhuthalele kwasakazwa imvelo.

Jellyfish ukudla zooplankton. Lezi ziphungumangathi zasondela kwezinye zezinhlobo zidla amaqanda nenhlanzi gazinga. Kodwa ngesikhathi esifanayo bona ngokwabo bayingxenye eziwukudla.

Hydroid (jellyfish), indlela yokuphila, eqinisweni, enikelwe ukudla, ngokuvamile ngokushesha kakhulu, kodwa-ke, awufiki ngezabelo ezifana stsifoidy. Ngokuvamile, ububanzi we hydroid isambulela esingeqile 30 cm encintisana main -. Izinhlanzi Planktivorous.

Yiqiniso, zingabantu ezizingelayo, futhi ngempela yingozi kubantu. Zonke jellyfish babe amaseli esintinyelayo, ezisetshenziswa ngesikhathi ekuzingeleni.

Uyini hydroids umehluko kusuka stsifoidov

Izici morphological kuyinto nokuba khona useyili. Stsifoidy akudingeki-ke. Avame ibe inkulu kakhulu futhi siphile kuphela ezilwandle nakuzo izilwandle. tsianeya Arctic ububanzi kufika ku 2 m, kodwa Isihlungu yayo lamaseli esintinyelayo akakwazi lokulimaza ezinkulu ukuze abantu. Khulisela usayizi esikhulu stsifoidam kusiza ezingaphezu kuka hydroids, inani osabalalayo iziteshi gastrovascular. Futhi ezinye izinhlobo jellyfish zidliwa ngumuntu.

Kukhona umehluko uhlobo motion - hydroids usike inkatho njengoba ngasesinqeni se isambulela futhi stsifoidy - insimbi egcwele. Ngezinye tentacles eside zokugcina eziyishumi nemitshingo sezinzwa. Ukwakheka kwazo ngokwama-ubuye ezahlukene, njengoba kungekho stsifoidov imisipha futhi izinzwa izicubu. Bahlale bekulungele dioecious, abanayo ukukhiqizwa kabusha vegetative kanye amakoloni. Lokhu olulodwa.

Scyphomedusae mihle ngendlela emangalisayo - they be of imibala ehlukene, babe amaphethelo egama kanye ukuma oluyinqaba insimbi. Kuyinto lezi ziboshwa ezase amanzi abe namaqhawekazi lwezinhlelo ze-TV mayelana kolwandle futhi ulwandle izilwane.

Hydroid jellyfish okungenakufa

Akunjalo kudala, ososayensi bathola ukuthi cnidarian jellyfish turitopsis nutrikula une-khono elimangalisayo rejuvenate. Lolu hlobo ukungalokothi ufa ukufa okujwayelekile! Kungaba ukusebenzisa izikhathi eziningi njengoba lo mshini ukuvuselelwa. Kunengqondo ukuphetha ngokuthi yonke into silula - eficwe ubudala, jellyfish saba ebuya ibe polyp futhi isidlulile zonke izigaba ukuvuthwa futhi. Futhi ngakho circle.

Nutrikula ehlala Caribbean futhi lincane kakhulu ngobukhulu - ububanzi yaba nesambulela sayo 5 mm.

Iqiniso lokuthi jellyfish hydroid ongafi, waziwa ngengozi. Usosayensi Fernando Boero kusuka Italy wafunda hydroids futhi baqhuba ucwaningo nabo. Abantu abaningana turitopsis nutrikula zafakwa aquarium, kodwa isipiliyoni ngasizathu simbe esalibele isikhathi eside kangaka, kodwa amanzi bomile. Boero, ukuyithola, wanquma ukutadisha izinsalela ezomisiwe, futhi ngaqaphela ukuthi abazange bafe, kodwa umane waphonsa ihambe futhi babe izibungu. Ngakho, jellyfish ezovumelana nezimo ezingezinhle kwemvelo futhi zakuklilals ilindele izikhathi ezingcono. Ngemva izibungu ibekwe emanzini baba polyp umjikelezo wokuphila sekuqalile.

abameleli Kuyingozi jellyfish hydroid

Ukubuka enhle kakhulu ubizwa ngokuthi umuntu-Portuguese (siphonophores Physalia) futhi ingenye zilwanyana zasolwandle eziyingozi kakhulu. insimbi wayo shimmers ngemibala ehlukene, njenge Izimbali Ezikhangayo kuye, kodwa ukuze asondele it is hhayi Kunconywa. Physalia ingatholakala ogwini-Australia, i-Pacific nasolwandle Indian, ngisho kuzo eMedithera. Mhlawumbe lena yiyona ndlela ingenye kwezinhlobo elikhulu hydroids - bubble obuphelele kungaba 15-20 cm Kodwa into embi - .. tentacles It, okungasisiza ukuya 30 m Physalia ukujula ukuhlasela izisulu zawo nge amaseli ezinesihlungu kabuhlungu ukuthi ushiye ukusha. Luyingozi kakhulu ukuhlangabezana abantu umkhumbi-Portuguese abaye esibuthaka sokuzivikela ezifweni, kukhona ukuthambekela komzimba.

Ngokuvamile, jellyfish saba hydroid akunangozi, ngokungafani nodade wabo stsifoidov. Kodwa ngokuvamile kungcono ukugwema ukuthintana nanoma iyiphi omele kwezinhlobo. Bonke ifa amaseli kabuhlungu. Ngoba umuntu ukuze ujike Isihlungu sabo akuyona inkinga, futhi umuntu ngeke ukulimaza eyingozi. Zonke kuya ngomuntu nomuntu.
