Achibale a slugs ndi nkhono zomwe zimakhala m'madzi am'nyanja, tikukamba za ndani? Zachidziwikire, zamayendedwe. Ndizomwe amachitcha gulu lina la gastropods okhala munyanja.

Masiku ano gululi lili ndi mitundu pafupifupi chikwi chimodzi, yomwe tatiuza munkhaniyi. Ndi chiyani chapadera pa nyama izi? Kodi amasiyana bwanji ndi abale ena potengera (ma mollusks)?

Choyamba, mawonekedwe oyamba. Ingoyang'anani kukongola kwapansi pamadzipo, ndikulondola kwa iwo kupanga "mpikisano wokongola wam'madzi", chifukwa zonse ndi zabwino kusankha, zabwino - imodzi ndi yabwino kuposa inayo! Mawonekedwe ake, mitundu yanji!

Koma kapangidwe ka thupi, sizosiyana ndi ma gastropod ena: "mwendo" womwewo, womwe umagwira ngati zida zamagalimoto, zotuluka zonse zofanana ndi thupi ndi maso ang'ono.

Mwa njira, izi zomwe zimatuluka (ma rhinophores) zikuyimira "dongosolo" lapadera lomwe limathandiza chidziwitso kuti chisanunuke, komanso kudziwa kukoma kwake.

Asayansi amatcha malowa chemoreception. Ndi khalidwe lapadera lotere, ma nulibranch mollusk amatha kupeza chakudya, kuyenda mozungulira ngakhale kubisala kwa adani.

Malinga ndi kapangidwe ka anatomiki ka mkati, ma nudibranch amagawidwa m'magulu awiri: eolides ndi doridids. Kupezeka kwa magilidwe ndi kapangidwe kake ka chiwindi kumasiyanitsa oimira magulu awiri awa: doridids imapereka magalasi enieni ndipo chiwindi chimakhala mkati mwa thupi ndipo chimakhala chiwalo chonse, chomwe sichinganene za eolides (alibe magiligili, ndipo chiwindi chimagawanika).

Nchiyani chimagwirizanitsa ma nudibranch onse? Choyamba ndi kusiyanasiyana kwamapangidwe amthupi: zimatha kusiyanasiyana kuzungulira mpaka kukhala chowongoka.

Chizindikiro chachiwiri ndi cha mbali yakunja kwa thunthu: Ma nollibranch mollusks amatha kukhala osalala, komanso okhala ndi ma tubercles, zitunda, zikwama, komanso masamba akutali.

Chabwino, chachitatu, chizindikiro chosangalatsa kwambiri chomwe chimagwirizanitsa ma nudibranch onse ndi penti yodabwitsa ya mitundu ndi mithunzi! Nyama izi zitha kupakidwa utoto, wamtambo, wachikasu, wofiyira, wachikasu, zobiriwira ... mitundu yonse singawerenge!

Koma kodi mumadziwa kuti mtundu wa mtundu womwewo wa nudibranch umatha kusintha ndikudalira mtundu wa chakudya chomwe udalawa izi zisanachitike? Izi zili choncho - zikuwonetsedwa ndi asayansi!

Ponena za mawonekedwe amthupi, ma nudibranch adadzipatula pano: mitsempha yosiyanasiyana, mawanga, mikwingwirima ndi zidutswa zimapangitsa zolengedwa izi kukhala zokongola zosamveka. Mutha kutsimikizira izi poyang'ana chithunzi cha aliyense woimira mabulogu a nudibranch.

Amagwirizanitsa gululi la oyerekeza moyo ndi moyo: onse ndi osakwatiwa. Kuphatikiza apo, titha kuonedwa ngati ma sebule osatha a seat, chifukwa amangoyenda osaka chakudya, ndipo alibe “nyumba”.

Monga chakudya, nyama zazing'ono zimasankhidwa kukasaka. Nthawi zambiri, menyu mwawo amakhala ndi oimira ma hydroids, masiponji, jellyfish yokhala, ma anemones am'nyanja, ma bryozoans, ngakhale mazira amitundu yosiyanasiyana.

Monga mukuwonera, "chakudya" cha nulibranch mollusks sichimasiyana mwachangu, koma sichingakhale choncho, chifukwa "osaka" okha amayenda pang'onopang'ono komanso movutikira.

Ma bulugamu a Nudibranch amatetezedwa kwa adani awo pogwiritsa ntchito mtundu wamtopola: thupi lopakidwa utoto wowala limawathandiza kubisala pakati pamiyala, motsutsana ndi mwala wamiyala yam'madzi, pansi pamtunda ndikupita osazindikirika.

Koma nthawi zina "zokhala ndi maso akulu" ndi zinsomba zimawonabe cholengedwa, kenako palibe chomwe chimatsala kuti anthu ena azisala kuti adye chakudya chamunthu wina.

Nudibranch (lat. Nudibranchia) - gulu la m'madzi am'madzi a pansi pa Heterobranchia. Zomwe zimapangidwazo zimaphatikizapo kusapezeka kwa chipolopolo komanso chovala chotchulidwa. Zilonda zapakhungu lawo ndi zofewa zosaoneka bwino zokhala ndi mawonekedwe osiyanasiyana ndipo zimakhala pambali kapena mbali yakumaso ya thupi; mwa mitundu ina, zotulutsa sizikupezeka. Ambiri omwe amakhala ndi nyanja zotentha komanso nyanja zamchere. Mitundu ina imakhala yapoizoni ndipo imakhala ndi mtundu wowala. Ma nudibranch onse ndi hermaphrodites. Zabwino kwambiri pankhani ya chakudya.
