Theodoxus hozhwa: zvirimo, kubereka, tsananguro, mufananidzo

Izvo zvakakosha zvemhando

Iyo genus ndeyemhuri yeNeretid. Kufanana nehama dzakawanda, vanogona kugara mumvura yakachena uye ine brackish. Saizi yavo inosvika paavhareji yemasentimita pakureba. Goko rakakomberedzwa, rine kakupeta zvishoma; kune vakawanda, yakaita sendiro kana kapu muchimiro. Pamusana pechiso chega pane chivharo, iyo mhuka inovhara mukova sezvinodiwa, seampoules. Iyo chete ndeyechiedza, chivharo nemukova zvine yero.

Rudzi rwe mollusks rwakasiyana chaizvo uye rwakanaka. Chimiro chehombodo chinopesana - mashizha makuru uye maduku kana intermittent zigzags pane chiedza chakareruka kana chakasviba. Magoko acho pachawo ane madziro akakora uye akatsikirira, akasimba kwazvo. Icho chokwadi ndechekuti mumasikirwo, mollusks inogara mumadziva ane simba razvino, uye ganda rakasimba rinongodiwa kwavari mumamiriro ezvinhu aya.

Mhando:

• Theodoxus danubialis (theodoxus danubialis) - mollusks akanaka kwazvo ane mateko e lime-white ruvara ane whimsical pateni yemazigzag akasviba ehukobvu hwakasiyana. Vanogona kukura kusvika imwe nehafu centimita. Vanoda mvura yakaoma.
• Theodoxus fluviatilis (theodoxus fluviatilis) - mhando yacho inoparadzirwa munzvimbo yakakura, asi panguva imwechete inofungidzirwa isingawanzoitiki. Yakagoverwa muEurope, Russia, nyika dzeScandinavia. Makungu akasviba muruvara - brown, bluish, purple, ane mavara machena akajeka. Vane tsika inofadza: vasati vadya algae, vanovakuya pamatombo. Nokudaro, ivhu rinosarudzwa nematombo.
• Theodoxus transversalis (theodoxus transversalis) - hozhwa diki, mateko asina patani, mavara kubva kune grey kusvika kune yero kana brown-yellow.
• Theodoxus euxinus (theodoxus euxinus) - molluscs ine goko reruvara rwakajeka, ine yakanakisa patani yemitsara mitete yakatyoka uye mapikisi. Vanogara munzvimbo dzinodziya - Romania, Greece, Ukraine.
• Theodoxus pallasi (theodoxus pallasi) - gara mumvura ine brackish uye ine munyu. Nzvimbo yakasikwa - Azov, Aral, Black Sea, nzizi dzemabheseni avo. Isingasviki centimita muhukuru, iwo mavara akasviba twumapupu uye mazigzags pane greyish-yellow kumashure.
• Theodoxus astrachanicus (theodoxus astrachanicus) - vanogara muDniester, nzizi dzeGungwa reAzov. Aya magastropods ane yakanaka kwazvo uye yakajeka goko pateni: anogara arima zigzags pane yero kumashure.

Ndivanaani theodoxus

Idzi ihozhwa duku kwazvo dzemvura yakachena dzinogara mumvura yeRussia, Ukraine, Belarus, Poland, Hungary. Vanowanikwawo munyika dzeBaltic neScandinavia.

Muchokwadi, vanogona kungonzi zvishoma mvura yakachena, sezvo mamwe marudzi eiyo Theodoxus genus anogara muAzov, Black uye Baltic Seas. Muchidimbu, mazana ezviuru zvemakore apfuura, ose aya gastropods aigara mumvura ine munyu yegungwa, uye mamwe marudzi zvishoma nezvishoma akatamira kune nzizi itsva nemakungwa.

Hapana exotic pakutanga kuona. Zvisinei, munhu haafaniri kuodzwa mwoyo nguva isati yasvika, ava vamiririri vepamba vekirasi ye gastropods vane mavara akasiyana-siyana ehombodo, maitiro anofadza, uye maitiro ekubereka. Pakupedzisira, dzakangonaka!

Hozhwa idzi dzakabudirira kurondedzerwa kwenguva refu, uye kwave uye hakuna kukakavara pamusoro penzvimbo yavo muchikamu chesainzi: kirasi Gastropoda (Gastropoda), mhuri Neritidae (Neretids), genus Theodoxus (Theodoxus).

Sezvo mutemo, idzi neretids dzinogara pamatombo akaoma, ayo anobatanidzwa nemhando yezvokudya zvavo. Vanokwenya diki algae uye detritus (zvisaririra zvezvinhu zvakaora zvakaora) kubva panzvimbo dzakaoma dzakafukidzwa nemvura.

Hozhwa dzinoita zvakanaka mumvura yakaoma. Uye izvi hazvishamise, nekuti ivo vanoda yakawanda karusiyamu kuvaka goko.

Vanhu vazhinji vangangove vakasangana nemamoluska aya munzizi nemadziva avo ekuzvarwa, asi vanhu vashoma vanofunga kuti vanogona kuchengetedzwa zvakabudirira muaquarium yavo diki nekuda kwechikonzero. Ivhareji yehupenyu hweNeretids inenge makore matatu.

gutsikana

Kuchengetwa kwehozhwa idzi dzinoshamisa hakuna kuoma zvachose. Ivo vanonzwa vakasununguka zvakaenzana patembiricha ye +19 uye pa +29. Vanodya algae, uye vanoshanda nesimba - ava ndivo vabatsiri vakanaka, nekuda kwekuti zviri nyore kuti muridzi wacho achengetedze aquarium yakachena. Ichokwadi, kusvibisa algae yakaoma, yakadai se "ndebvu nhema", yakanyanya kuvaomera. Hozhwa dzinosiya zvidyarwa zvepamusoro zvisina kusimba - uku ndiko kuwedzera kwavo kukuru. Sezvo mutemo, iyo aquarium inogara gastropods iyi inogara ichitaridzika zvakanaka, uye zvinomera mairi zvakachena uye zvine hutano.

Mhando dzakawanda dzemollusks dzinosarudza mvura yakaoma yakaoma, yakawanda mu calcium - inoda iyo kune goko rakasimba. Iwe unogona kuisa matombo egungwa (limestone) mukati mawo mu aquarium (uchifunga, zvechokwadi, zvinofarirwa nevamwe vagari ve aquarium). Havadiwo mvura isingayerere.

Hozhwa dzinenge dzisiri pasi pe6-8 panguva imwe chete. Iwo achiri madiki, saka munhamba diki haungazvione mu aquarium. Mukuwedzera, huwandu hwakadaro hunodiwa pakubereka. Icho chokwadi ndechekuti ma mollusks aya ese ari maviri echirume uye ane bisexual, uye panguva imwechete varume havana kusiyana nevakadzi zvachose.

Chinhu chinonakidza chehunhu hweava vagari vakanaka vemu aquarium ndechekuti mumwe nemumwe wavo ane nzvimbo yake mu "mhuri". Iyi ndiyo nzvimbo inozorora chipfuyo uye nharaunda yeuXNUMXbuXNUMXbnzvimbo iyo "yainoita". Sezvo mutemo, iyi inzvimbo yakaoma - vanoifarira kune mashizha nemashizha emiti. Zvinowanzoitika kuti diki theodoxus inogadzika pagoko rema mollusks makuru. Hozhwa dzakanyatsojeka uye nenzira dzakajeka nzvimbo dzadzo dzekusvibisa, uye kushomeka kwakanyanya kwechikafu kunogona kuvamanikidza kusiya miganhu yenzvimbo ino.
