I-Tadpole Shrimp

Aqanjwe ngokufanelekile: izimfanzi ze-tadpole zohlobo lwe-Triops. Ngoba sekuyiminyaka engaphezu kwezigidi ezingu-200 kuthiwa cishe azishintshile emhlabeni. Noma ngabe ucwaningo lwakamuva lubeka iminyaka eminyakeni eyizigidi ezingama-70, babephila ngesikhathi sama-dinosaurs futhi basinda ekufeni kwawo. Izinhlobo ezimbili ezinakekelwa kakhulu.

Amaqiniso athakazelisayo mayelana ne-Tadpole Shrimp

Igama lesayensi

I-Triops longicaudatus ne-T. cancriformis

Amanye amagama

Lutho; Nokho, kukhona subspecies futhi kuyaqabukela ukugcinwa ezinye izinhlobo nokubukeka okufanayo

Ezesistimu

• I-sub-strain: I-crustacea (ama-crustaceans)
• Ikilasi: I-Branchiopoda (ama-gill pods)
• I-oda: I-Notostraca (isikhafu sangemuva)
• Umndeni: I-Triopsidae (i-Tadpole Shrimp)
• I-Genus: Triops
• Izinhlobo: Igobolondo lofudu lwaseMelika, i-Triops longicaudatus (T. l.) Kanye negobolondo lofudu lwasehlobo i-Triops cancriformis (T. c.)

Usayizi

Igobolondo lofudu lwaseMelika ngokuvamile likhula lifinyelele ku-6 cm ubude, ezimweni ezingavamile futhi libe ngu-8 cm. Izimfanzi zesihlangu sasehlobo zingakhula ngokuphawulekayo zibe zinkulu, zize zifike ku-8 cm zivamile, kodwa izibonelo ezifika ku-11 cm ubude azivamile.

Color

Isihlangu singaba beige, sibe luhlaza okotshani, sibe luhlaza okwesibhakabhaka, noma sicishe sibe pink ngombala. Amehlo amabili amakhulu ekugcineni kwesihlangu ayabonakala. Phakathi, kukhona iso lesithathu elifihliwe elingasetshenziswa ukuthola umehluko ekukhanyeni. I-underside ingaba nemibala eminingi kakhulu, ngezinye izikhathi ibe namathoni abomvu aqinile.

Origin

T. T. c.: IYurophu, kuhlanganise neJalimane. Amancane, ashiswe kakhulu elangeni, ama-micro-bodies amanzi (ama-puddles) avame ukuba khona amasonto ambalwa agcwele, eJalimane ngokuvamile ezindaweni ezigcwele izikhukhula zemifula.

Ukungafani kobulili

Kwa T.l. kunezindlela ezahlukene zokukhiqiza. Imvamisa isibalo sabantu sihlanganisa abesifazane kuphela abazalela amaqanda avundiswa unomphela. Bese kuba nama-hermaphrodite, lapho kufanele kube nezilwane ezimbili, futhi ekugcineni, kube nenani labantu lapho kukhona khona abesilisa nabesifazane kodwa abahlukaniseki. Kwa T.l. cishe zonke izibonelo zingama-hermaphrodites azivundisa ngokwazo. Ngakho isilwane sesivele siyindlela yokuzalanisa.

Ukukhiqiza

Amaqanda abekwe esihlabathini. I-nauplii encane, esakwazi ukubhukuda mahhala ingachanyuselwa kubo. Amaqanda amaningi, nokho, adinga isigaba sokumisa, esivumelaniswe nezimo zemvelo, okungukuthi ukuhlala emanzini omisiwe. Amaqanda (empeleni ama-cysts, ngoba umbungu usuqalile ukukhula lapha, kodwa bese uyama kuze kube izimo ziba ngcono futhi) cishe. 1-1.5 mm ubukhulu. Angasuswa ngesihlabathi (ezinye izinhlobo ezinamaqanda anombala nazo zingavunwa zihlanzekile). Bese zomiswa kahle kakhulu futhi zigcinwe efrijini. Ngemva kwezinsuku ezintathu kuya kwezine, i-nauplii ikhula ibe ama-trip amancane, aphinda kabili ubude bawo nsuku zonke. Ukukhula kukhulu, ngemva kwezinsuku ezingu-8-14 sebevuthiwe ngokocansi. Ngemva kwalokho ungabekela amaqanda angaba ngu-200 ngosuku.

Isikhathi sokuphila

Iminyaka yokuphila ayiphezulu, phakathi kwamasonto ayisithupha neshumi nane kuyinto evamile. Lokhu kuwukujwayela ukuthi izindawo zabo zokuhlala ziyasha.

Amaqiniso athakazelisayo

Nutrition

Ama-Triops angama-omnivores. Ama-nauplii anikezwa i-spirulina algae noma ukudla okuyimpuphu (infusoria). Ngemuva kwezinsuku ezintathu, ukudla kwe-flake kwezinhlanzi zokuhlobisa kunganikezwa, futhi ngemva kwezinsuku ezinhlanu kungenziwa kungezwe ngokudla okuqandisiwe futhi (iqhwa) okomisiwe okuphilayo.

Usayizi weqembu

Isilwane esikhulile kufanele sibe namalitha amabili kuya kwamathathu esikhala. Izilwane ezincane zingagcinwa zisondelene kakhulu. Njengoba kufanele bakhiphe isikhumba sabo njalo bese beba negobolondo elithambile, ubuzimu obuthile bujwayelekile futhi ngeke buvinjwe.

Usayizi we-aquarium

Izitsha zokuchanyuselwa zezimila zidinga amalitha ambalwa kuphela, izindawo zokugcina kanye nokuzalela kwazo kufanele okungenani zibe namalitha ayi-12. Yiqiniso, ayikho imingcele ephezulu.

Imishini yephuli

Izinhlanzi zasemanzini ezichanyuselwa azinawo umhlobiso. Ungqimba oluncane lwesihlabathi somfula ocolekileyo ku-substrate lubalulekile ezilwaneni ezivuthiwe ngokocansi. Ezinye izitshalo zinciphisa okuqukethwe okungcolile kwabadla kakhulu, umoya omncane uqinisekisa umoya-mpilo owanele. Ukukhanyisa kunengqondo, kodwa akufanele kushise amanzi.

Hlangana noTadpole Shrimp

Kungenzeka ngempela ukuhlangana nezimfanzi ze-tadpole nezinye izinhlobo ze-crustaceans (njenge-gill foot evamile (Branchipus schaefferi), nazo ezenzeka emvelweni). Kodwa-ke, kungcono ukuyigcina ku-aquarium yezinhlobo.

Amanani amanzi adingekayo

Ukuze achanyuselwe, ama-cysts adinga amanzi ahlanzekile kakhulu, athambile (okuthiwa "amanzi acwecwe", i-osmosis ehlehlayo, noma amanzi emvula). Izilwane ezikhulile azizweli kakhulu, ngenxa ye-metabolism ephezulu (cishe i-40% yesisindo somzimba idliwa ngosuku) ingxenye yamanzi kufanele ishintshwe njalo ezinsukwini ezimbili.

Amazwi

Kwezohwebo, kukhona ikakhulukazi u-T. l., Okungavamile kakhulu u-T. c. Kodwa ezinye, ngezinye izikhathi ezinemibala elinganiselwe, izinhlobo nazo ziyatholakala kochwepheshe, abanezidingo ezifanayo mayelana nokugcinwa nokuzalanisa. Amakhithi okuhlola ahlukahlukene aqukethe zonke izesekeli ezidingekayo ayatholakala ezitolo zamathoyizi. Kodwa-ke, ezinye zazo ziqukethe izinkalankala ze-Artemia, okufanele zigcinwe emanzini anosawoti, zidlule ekuthuthukisweni okufanayo, kodwa zihlala zincane kakhulu (ngaphansi kuka-2 cm nje), futhi kunzima kakhulu ukuzigcina.
