Namuhla sizokhuluma ngenhlanzi ekhetheke kakhulu. Futhi ngithi ngikhetheke kakhulu ngoba ku U-2013 uthathwe njengesilwane esibi kunazo zonke emhlabeni. Imayelana nenhlanzi eyehliswayo.
I-dropfish, igama lesayensi (Psychrolutes marcidus), yaziwa nangokuthi i-blob fish noma ijanaira. NgesiNgisi yaziwa ngokuthi i-globfish. Okomndeni de peces enekhanda elinonile futhi inezici ezithile ezenza ihluke emhlabeni wezinhlanzi. Uyafuna ukwazi okwengeziwe ngesilwane esibi kunazo zonke emhlabeni?
Indawo nendawo okusatshalaliswa kuyo
IDropfish itholakala emanzini ajulile asenkabeni yeTasmania nase-Australia. Kutholakala ikakhulukazi kulezi zindawo, noma singakuthola naku amanzi aseNew Zealand.
Yinhlanzi engajwayelekile ebusweni, ngakho-ke kunzima ukuyibona ngamehlo. Ngokuvamile kutholakala ekujuleni phakathi kuka-900 no-1200 metres lapho ingcindezi yamanzi iphindwe izikhathi eziphindwe kayishumi kunaleyo engaphezulu kolwandle. Lesi ngesinye sezizathu esenza le nhlanzi ingaziwa kahle.
Akubhekwa nje kuphela njengesilwane esibi kunazo zonke emhlabeni ngobuso baso noma ukubukeka kwaso, kepha nangenxa yesikhumba saso. Inyama yalezi zinhlanzi idinga ukuntanta ngakho-ke yakhiwa izicubu ze-gelatinous ezinesisindo esiphansi kunaleso samanzi. Ngenxa yalolu hlobo lwesikhumba esincane kakhulu, luyakwazi ukuntanta olwandle ngaphandle kokuphelelwa amandla okubhukuda.
Izici eziyinhloko
Abantu abake babona le nhlanzi bathi ibukeka inyanyeka futhi ukuthinta okune-gelatin kuyesabeka. Inombala kakhilimu futhi ubude obungu-30 kuya ku-38 cm obwenza inhlanzi enkulu ngokwanele.
Ukuba nomzimba onobuningi obuphansi kangako, abanamandla amakhulu. Ngakho-ke, akuzona izinhlobo ezikhuthele kakhulu futhi ngokuvamile azizingeli izilwane zazo. Ziphila ngokudla ezikuthola endleleni. Ngenxa yokutholakala kwayo ngokweqile, ososayensi abaningi baye bakungabaza ukuba khona kwayo kweqiniso, njengoba kubonakala kufana nefilimu eqanjiwe yesayensi kuneqiniso. Kepha kwesinye isikhathi kufanele ulalele isisho leso "iqiniso lidlula inganekwane".
Inekhanda elikhulu kakhulu namaphiko amancane impela, ngemuva nangomsila. Ibizwa nge-drop fish ngoba yakheke njengethonsi lamanzi lapho iwa. Ekhanda inekhala elenga elikhulu, elibonakalisiwe futhi eliyindilinga namehlo amabili abekwe ekhoneni lapho kuzalwa khona ikhala. Kokubili amehlo namakhala kunesimo esifana nejeli esikwenza ube mkhulu.
Mayelana nokuminyana kanye nesisindo somzimba, kufanele kushiwo ukuthi ziphansi kakhulu ukuze zikwazi ukuntanta olwandle ngaphandle kokuthi ziqede amandla azo ngokubhukuda. Ngokungafani nabanye de peces, akanaso isinye sokubhukuda. Lesi sitho sivamile eningini elikhulu de peces futhi bayisebenzisela ukukwazi ukuhlala intanta emanzini ngaphandle kokuza phezulu. Kuyisitho esibalulekile kuzo zonke izinhlanzi. Nokho, i-blob fish ayinayo ngoba ayidingi. Ngobunzima obuncane kanye nokuminyana umzimba wayo onakho, kakade sekwanele ukuthi ihlale intanta ngaphandle kokudinga isinye sokubhukuda.
Izinhlanzi zicindezelwa kakhulu kusuka ekujuleni kwamanzi. Ngenxa yesikhumba sokubhukuda bayakwazi ukunqoba le ngcindezi ngaphandle kokuhlakazeka. Yebo, inhlanzi eyehlayo ibe nokuvela okuhlukile okwenza umzimba wayo ube nokuxinana okuphansi. Lesi yisizathu esenza ukuthi le nhlanzi ihlale kulezi zindawo ezinamanzi.
Kubude obungu-38 cm, akusikho ukuthi kuyakhazimula kakhulu, kepha kuyadonsela ukunakwa lapho kubonwa usayizi omkhulu wekhanda maqondana nomzimba wonke. Ngenxa yokwakheka komzimba wayo iyakwazi ukumelana namazinga okushisa aphansi kakhulu. Okufanele kakhulu kuphakathi kuka-2 no-9 degrees Celsius.
Ukudla nokuziphatha
Njengoba idla ngokutholakala olwandle, ukudla kwalo kuhluka kakhulu. Bayakwazi ukondla kuzo zonke izinhlobo zezinto eziphilayo ezizungezile. Lezo ezimiswe emanzini zivame kakhulu. Sithola ama-crustaceans amancane nama-mollusks, ezinye izinto eziphilayo ngisho nemichamo yolwandle.
Yize ingenawo amazinyo okuhlafuna ukudla, le nhlanzi akanankinga lapho edla noma yiluphi uhlobo lokudla, ngoba zinohlelo lokugaya ukudla olunamandla omunci omkhulu nolonakalisayo.
Njengoba ukudla okukujula kolwandle kungagcini kakhulu, inhlanzi eyehlayo intanta ngokuthula ngaphandle kwamandla aqedayo alinde ukuthola ukudla. Akuyona inhlobo ezingela isisulu sayo.
Ukuzala
Ukukhiqizwa kabusha kwale nhlanzi, kunikezwe indawo okwabiwa kuyo, kunzima ukwazi. Ngaphezu kwalokho, kuyinhlobo eyatholakala kungekudala, ngakho-ke akukho mininingwane eminingi. Kwezinye izikhathi kuye kwabikwa ukuthi lezi zinhlanzi zizalela amaqanda azo olwandle nokuthi zihlala endaweni eziseduze ukuze zivikelwe futhi ziqashwe. Lezi zibhangqwana zibekwa phezu kwazo ngendlela efanayo nezinyoni.
Lapho izinsuku zidlula futhi amaphuphu eqanduselwa emaqandeni, abazali ngeke bahlukane nabo ukuze bavikeleke ezilwaneni ezizingelayo. Benza lokhu ngoba olwandle alukho ulwelwe noma ukwakheka kwamatshe lapho amaqanda angavikelwa khona ngeso lenyama kwabanye. Awukwazi ukubeka amashidi ukumboza.
Lapho insikazi izalela amaqanda, uyakwazi ukubeka izinkulungwane eziningana zazo namaqanda abo abomvana hhayi amhlophe, njengoba kuvame kakhulu.
Izinsongo zokudotshwa kwezinhlanzi
Yize lezi zinhlanzi zihlala ekujuleni zisongelwa yizenzo ezithile zomuntu. Okokuqala kungenxa yezindawo zokudoba ezishubisa umnkantsha zezinkampani ezithile zasolwandle. Le ndlela yokudoba ibhubhisa olwandle futhi ithinte nenhlanzi eyehliswayo, phakathi kwezinye izinhlobo eziningi.
Ngisho noma inhlanzi ingabanjwanga ngokuphelele, ukuyisusa ebangeni layo lokujula kungathinta umzimba wayo ngokungathi sína. Izinguquko zengcindezi engazelelwe zibathinta kakhulu.
Njengoba ubona, ekujuleni kolwandle kukhona zonke izinhlobo de peces izici ezingavamile ezingayeki ukusimangaza.
