Maluwa otchedwa cuttlefish (Metasepia pfefferi) kapena Pfeffer's cuttlefish ndi a kalasi ya cephalopod, mtundu wa molluscs.
Kufalitsa kwa cuttlefish yamaluwa.
Mbalame yotchedwa cuttlefish imagawidwa mdera lotentha la Indo-Pacific Ocean. Amapezeka makamaka pagombe la kumpoto kwa Australia, Western Australia, komanso kumwera kwa Papua New Guinea.
Zizindikiro zakunja kwa cuttlefish yamaluwa.
Maluwa otchedwa cuttlefish ndi kanyama kakang'ono ka cephalopod mollusk, kutalika kwake kumakhala mainchesi 6 mpaka 8. Mkazi ndi wamkulu kuposa wamwamuna. Oyimira onse a Metasepia ali ndi mitima itatu (mitima iwiri ya gill ndi gawo lalikulu la magazi), dongosolo lamanjenje ngati mphete, ndi magazi amtambo okhala ndi mankhwala amkuwa. Maluwa otchedwa cuttlefish ali ndi zida 8 zokulirapo zomwe pamakhala mizere iwiri ya ma suckers. Kuphatikiza apo, pali mahema awiri omata, omwe ali ofanana ndi maupangiri ku "zibonga".
Pamwamba pazomata zomata ndizosalala m'litali lonse, ndipo kumapeto kwake kokha amakhala ndi zoyamwa zazikulu. Maluwa odulidwa ndi nsomba zamtundu wakuda. Koma kutengera momwe zinthu zilili, thupi lawo limavala zoyera ndi zachikaso, ndipo zotsekerazo zimakhala zofiirira-pinki.
Khungu la cephalopods limakhala ndi ma chromatophores ambiri okhala ndi ma pigment, omwe maluwa a cuttlefish amatha kuwongolera mosavuta kutengera chilengedwe.
Amuna ndi akazi amakhala ndi mithunzi yofanana, kupatula nyengo yokhwima.
Thupi la cuttlefish limakutidwa ndi chovala chowoneka bwino kwambiri, chowulungika, chomwe chimagwetsa pansi mbali yamtambo. Kumbali yakumaso kwa chovalacho, pali mitundu itatu yamitundu ikuluikulu, yopanda pake, yamapepala yomwe imaphimba maso. Mutu ndi wocheperako pang'ono kuposa mkanjo wonse. Kutsegula pakamwa kuzunguliridwa ndi njira khumi. Mwa amuna, mahema awiri amasandulika kukhala hectocotylus, zomwe ndizofunikira pakusungira ndi kusamutsa spermatophore kwa mkazi.
Mtundu ukusintha kwamaluwa a cuttlefish.
Maluwa a cuttlefish amakhala makamaka pagawo lazitsulo. Malo okwera m'mapiri a zinyalala zokhazikika amakhala ndi zinthu zambiri zomwe nsomba zam'madzi zimadyetsa. M'malo oterewa, ma cephalopods amawonetsa kubisa kodabwitsa komwe kumawalola kuti azitha kuphatikizika bwino.
Pakawopseza moyo, maluwa otchedwa cuttlefish amasintha mitundu yosintha kukhala yofiirira, yachikaso, ndi yofiira.
Kusintha kwamtundu wamtunduwu kumadalira ntchito ya ziwalo zapadera zotchedwa chromatophores. Zochita za chromatophores zimayendetsedwa ndi dongosolo lamanjenje, motero mtundu wa thupi lonse umasintha msanga chifukwa chakuchepetsa kwa minofu yomwe imagwira ntchito limodzi. Mitundu yautoto imayenda pathupi lonse, ndikupanga chithunzi cholakwika. Ndizofunikira pakusaka, kulumikizana, kuteteza komanso kubisala kodalirika. Kumbali yakumaso kwa chovalacho, mikwingwirima yofiirira nthawi zambiri imadutsa m'malo oyera, mawonekedwe amtunduwu adapatsa mtunduwo dzina "maluwa a cuttlefish". Mitundu yowala imeneyi imagwiritsidwa ntchito kuchenjeza zolengedwa zina ku ziyizoni za ma cephalopodswa. Akaukiridwa, maluwa otchedwa cuttlefish samasintha mtundu kwa nthawi yayitali ndikugwedeza mawonekedwe awo, kuchenjeza mdani. Pomaliza, amangothawa, ndikutulutsa mtambo wa inki kuti usokoneze nyamayo.
Malo okhala maluwa odula.
Maluwa otchedwa cuttlefish amakhala m'madzi akuya kuchokera pa 3 mpaka 86 mita. Amakonda kukhala pakati pamagawo amchenga ndi matope m'madzi otentha.
Kubalana kwa maluwa a cuttlefish.
Maluwa otchedwa cuttlefish dioecious. Akazi nthawi zambiri amakwatirana ndi amuna ambiri.
Amuna m'nyengo yoswana amakhala ndi mitundu yokongola kuti akope akazi.
Amuna ena amatha kusintha mtundu wawo kuti aziwoneka ngati wamkazi kuti apewe wamwamuna wankhanza kwambiri, komabe amayandikira pafupi ndi akazi kuti akwere.
Mbalame zotchedwa cuttlefish zimakhala ndi umuna mkati. Amuna ali ndi chiwalo chapadera, hectocotyl, chomwe chimagwiritsidwa ntchito kusungira ndi kunyamula ma spermatophores (mapaketi a umuna) kupita kudera lachikazi nthawi ya mating. Mkazi amatenga ma spermatophores okhala ndi mahema ndikuwayika pamazira. Pambuyo pa umuna, yaikazi imaikira mazira amodzi m'ming'alu ndi m'ming'alu yakunyanja kuti ibisalire ndi kuteteza ku adani. Mazira ndi oyera osati ozungulira; kukula kwawo kumadalira kutentha kwa madzi.
Nsomba zazikuluzikulu sizisamalira ana; akazi, atayika mazira m'malo obisika, amamwalira atabereka. Kutalika kwa nthawi yayitali yamaluwa a cuttlefish m'chilengedwe kuyambira miyezi 18 mpaka 24. Mitundu iyi ya cuttlefish imasungidwa kawirikawiri mu ukapolo, chifukwa chake, zomwe amachita mu ukapolo sizinafotokozeredwe.
Makhalidwe a cuttlefish.
Maluwa a cuttlefish ndi osambira pang'onopang'ono poyerekeza ndi ma cephalopods ena ngati squid. "Fupa" lamkati limagwiritsidwa ntchito kuwongolera kuyamwa poyang'anira kuthamanga kwa gasi ndi madzi omwe amalowa muzipinda zapadera za cuttlefish. Popeza "fupa" ndi laling'ono kwambiri poyerekeza ndi chovalacho, nsomba za cuttlefish sizimatha kusambira kwa nthawi yayitali kwambiri ndipo "zimayenda" pansi.
Maluwa otchedwa cuttlefish ali ndi maso abwino kwambiri.
Amatha kuzindikira kuwalako, koma masomphenya awo alibe utoto. Masana, maluwa otchedwa cuttlefish amatakasaka nyama.
Mbalame zotchedwa Cuttlefish zili ndi ubongo wabwino, komanso ziwalo zowonera, kukhudza ndikumverera kwa mafunde amawu. Mbalamezi zimasintha mtundu potengera malo amene zikuzungulira, mwina kuti zikope nyama kapena kupewa nyama zolusa. Nsomba zina zotchedwa cuttlefish zimatha kuyenda m'mazira pogwiritsa ntchito zithunzi.
Kudyetsa maluwa okongola a cuttlefish.
Maluwa a cuttlefish ndi nyama zolusa. Amadyetsa makamaka nkhanu ndi nsomba zamathambo. Pogwira nyama, mbalame zamaluwa zokongola zimatayira kutsogolo kwawo ndikugwira wovulalayo, kenako ndikubweretsa "m'manja" mwawo. Mothandizidwa ndi pakamwa ndi lilime lopangidwa ndi pakamwa - radula, yofanana ndi burashi ya waya, cuttlefish imayamwa chakudya m'magawo ang'onoang'ono. Zakudya zazing'ono ndizofunikira kwambiri pakudyetsa, chifukwa cuttlefish esophagus sangaphonye nyama yayikulu kwambiri.
Kutanthauza kwa munthu.
Maluwa otchedwa cuttlefish ndi amodzi mwamitundu itatu yodziwika bwino ya cephalopods. Mafinya a Cuttlefish ali ndi zoyipa zofananira ndi poizoni wa octopus wa buluu. Izi ndizowopsa kwa anthu. Kapangidwe ka poizoni kumafuna kuphunzira mwatsatanetsatane. Mwina itha kugwiritsidwa ntchito ngati mankhwala.
Malo oteteza maluwa a cuttlefish.
Maluwa a cuttlefish alibe mwayi wapadera. Palibe chidziwitso chochepa chokhudza moyo wama cephalopods awa kuthengo.
