Okuqukethwe
I-Sticklebacks umndeni wezinhlanzi ohlanganisa izinhlobo eziningana ezinezinhlobo ezingaba ngu-18. Lezi yizinhlanzi ezincane, ezibonakala ngesakhiwo esingavamile nendlela yokuphila. Zingase zehluke ezicini ze-morphological komunye nomunye, kodwa zonke zinemigogodla phambi kwe-dorsal fin. Basebenzisa le migogo ukuze bazivikele. Ngaphezu kwalokho, amanye ama-stickleback anama-spikes ohlangothini lwesisu, kanye namapuleti amathambo, njll. isihlangu sesisu. Hlukanisa olwandle, amanzi ahlanzekile kanye ne-stickleback ehlala emanzini anosawoti. Izinhlanzi azifani nje kuphela endaweni yokuhlala nokubukeka, kodwa futhi nokuziphatha. Amanzi ahlanzekile akhetha indlela yokuphila yesikole, futhi olwandle, ama-stickleback ahlangana ngamaqembu amakhulu kuphela ngesikhathi sokuzala. Ubukhulu bezinhlobo eziningi buyahlukahluka kusuka ku-7-12 cm. Izinhlobo zasolwandle zingafinyelela ku-20 cm. Ngenxa yobukhulu bazo, i-stickleback kunzima ukuyihlukanisa "njengenhlanzi ye-trophy". Naphezu kwalokhu, idlangile futhi ithathwa njengesilwane esizingelayo esisebenzayo. Izazi ze-Ichthyologists zithi i-stickleback inolaka futhi ivame ukuxabana nomakhelwane ekuphileni kwayo okujwayelekile, ingasaphathwa inkathi yokuzalanisa. Ukuzingela kusuka ekuqamekeleni. Izinhlobo ezihlukene ze-stickleback zivamile ezifundeni eziningi futhi zingabanjwa ngokungaziwa kuzo zonke izinkathi zonyaka. Engxenyeni yaseYurophu yaseRussia, izinhlobo ezingama-4-5 zihlukaniswa. E-Kronstadt, kwakhiwe ukwakheka okuqoshiwe - "isikhumbuzo se-stickleback evinjezelwe", eyasindisa izinkulungwane zezimpilo eLeningrad evinjezelwe.
Izindlela zokubamba i-stickleback
I-Stickleback ingabanjwa ngezindlela ezihlukahlukene, ngisho nangezidobo ezincane ezibukhoma. Ngokukhethekile ukuyibamba, njengomthetho, ama-anglers - abathandi bayakugwema. Isizathu akuwona nje ubukhulu, kodwa futhi nemigqa yezinhlobo ezithile, ezingabangela ukusikeka okubuhlungu. Ngesizathu esifanayo, i-stickleback ayivamile ukusetshenziswa njenge-bait ephilayo noma ukusika. Noma kunjalo, uma kwenzeka kunqwabelana izinhlanzi endaweni yokudoba, ingabanjwa ngempumelelo kokubili ngegiya lasebusika nelasehlobo. Ama-angle amancane athola injabulo ekhethekile ekubambeni i-stickleback. Ukuminza kwenza le nhlanzi igijime ngisho nangehhuku elingenalutho. Ukudoba okuncane "okuthakazelisayo" kungenzeka ngesikhathi "sokuntuleka kokuluma", echibini lasebusika, lapho ubamba ezinye izinhlanzi. Ebusika, i-stickleback "ivunwa" ukuze kusetshenziswe amagiya ahlukahlukene, kokubili phansi, nokunqekuzisa nokugedla. Ehlobo, izinhlanzi zibanjwa kusetshenziswa i-float evamile nephansi.
Amahubo
Ehlobo nasebusika, izinhlanzi zibanjwa ngokudla kwezilwane, kuhlanganise nokuthosa. Kuye ngesifunda kanye nedamu, kungase kube nezici zabo siqu. Kodwa uma ucabangela ukuhaha nomsebenzi wale nhlanzi, ungahlala uthola isiyengo se-nozzle. Ngezinye izikhathi ungasebenzisa ngisho nezindlela ezithuthukisiwe - ucezu lwe-foil nokunye.
Izindawo zokudoba kanye nezindawo zokuhlala
I-Ichthyologists ibheka i-stickleback njengezinhlobo ezisakazeka ngokushesha. Uma kunezimo ezivumayo, inganweba indawo yayo yokuhlala. Abanye ososayensi baphikisa ngokuthi i-voracity kuphela evimbela ukusatshalaliswa okukhulu kwalezi zinhlanzi: zivame ukudla izingane zezinhlobo zazo. Izinhlobo ezihlukahlukene ze-stickleback zivamile emiphongolweni cishe yazo zonke izilwandle zaseRussia, kodwa eSiberia naseMpumalanga Ekude, izinhlanzi, ikakhulukazi, zinamathela emanzini asolwandle namanzi anosawoti. Ngaphezu kwalokho, i-stickleback ihlala emifuleni emikhulu yaseSiberia futhi ingasakazeka kuze kube maphakathi. I-sea stickleback ihlala endaweni esogwini, ayifaki ukugxila okukhulu. Izinhlobo zamanzi ahlanzekile zivamile, ngaphandle kwemifula, emachibini nasemachibini, lapho zihlala khona ziyimihlambi emikhulu.
Ukuzalela
Ngokwehlukana, kufanelekile ukuhlala ku-stickleback, njengohlobo, ngenxa yokuzalana. Ngaphezu kweqiniso lokuthi izinhlanzi zivikela inzalo, zakha izidleke zangempela ezitshalweni zasemanzini, okuyizakhiwo eziyindilinga ezinendawo ngaphakathi. Eyeduna yakha futhi igada isidleke, ngalesi sikhathi ayikwazi ukudla ngenxa yezinguquko zomzimba ohlelweni lokudla. Insikazi izalela amaqanda ambalwa. Intsha, ngesikhathi sokuthuthuka, ihlala ngaphakathi kwale ndawo isikhathi eside (cishe inyanga). Ngaphambi kokuzala, abesilisa bashintsha umbala, izinhlobo ezahlukene ngezindlela ezihlukene, kodwa likhanya.
