Sea onogwaja, ayini?

On emashalofini of Russia ngokwethukela yaqala ukubonakala izinhlanzi ngokuthi "ulwandle unogwaja" noma "Ulwandle hare" (isithombe ungabona kulesi sihloko). Ngokuvamile, bayidayise ngaphandle amakhanda, futhi abaningi unombuzo: "? kanjani empeleni le nhlanzi ibukeke" Ngokushesha kuyafaneleka ukuthi onogwaja ulwandle - akuzona izinhlanzi kuphela, kodwa futhi abameleli lwezimpawu. Kodwa lapha kuzoba nje mayelana izinhlanzi.

onogwaja Sea akuzona aminingi ukudlula Chimera European. Le nhlanzi ekujuleni kolwandle benthic elingelakwaJuda kuya subclass ka cartilaginous izinhlanzi slitnocherepnyh noma holocephali. Kuze kube manje, kukhona omunye Chimaeriformes lamabutho (Chimaera). Bona bahlala eshalofini kanye emthambekeni eshalofini yezwekazi a ka 2500 amamitha ukujula e-Indian, Atlantic nePacific. Norway futhi Iceland lubhekisele oLwandle iMedithera, oLwandle uBarents futhi ngasogwini South Africa kukhona ulwandle onogwaja.

Chimeras kukhona, nakuba elikude, kodwa izihlobo oshaka yesimanje. Ngezinye izikhathi ibizwa ngokuthi "isipoki oshaka". Ezikhathini zasendulo, lezi abameleli izilwandle babe okhokho ezivamile, kodwa iminyaka eyizigidi ezingu-400 edlule, zahlukaniswa 2 iqembu. Ezinye steel siphephele eduze kwamanzi, kanye nezinye phansi ukujula futhi balolonge nge isikhathi atholwe Chimera yesimanje.

onogwaja Sea ubude ngokuvamile ingeqi 1.5 amamitha; inxenye eside, umsila nomzimba omncane. amaphiko ayo amaphiko aqale kusukela phakathi emuva luphele ichopho umsila. Ngokuvamile, amaphiko izinhlanzi zifana kakhulu amaphiko, futhi ngakho-ke kubonakala sengathi musa ukubhukuda, futhi fly. Phambi fin izinhlanzi darnel (isithombe kukuveza obala loku) it has ameva ezinesihlungu, okuyinto ngokuphelele ezitheni zawo. Kodwa-ke kumelwe kuthiwe chimeras akuzona okungaka. Izitha zabo eziyinhloko makhulu elinganeliseki indiakantov zesifazane. Ingozi enkulu esongela abameleli ezisencane ulwandle onogwaja, futhi livela izihlobo zabo manje okude - oshaka. Ngo chimeras ibala ziyahlukahluka kusuka ompungana cishe abamnyama. Kungaba okungafani izindawo ezinkulu.

onogwaja Sea kuthiwa ezingelwa ngokwabo, kanye nezinye izakhamuzi zaseMpumalanga ekujuleni, uma uyithinta. Isibaluli kuphela ukuze ahehe inyamazane - umugqa ebucayi lateral. Ngezinye yakhe sengathi, baphendukele ekukhanyeni, ukufuna ukwazi mollusk, izimpethu, ezinamagobolondo, echinoderms kuphela nezinhlanzi ezincane. Kodwa ilukuluku enjalo ezimweni eziningi izophela imihlathi a Chimera. Futhi emhlathini wakhe oqinile nge amareyi ama-3 namazinyo aqinile kakhulu wajinge wanamatsela kalula ngisho amagobolondo sekukaningi.

Ngenxa Indawo idatha izinhlanzi ukufunda nzima kakhulu. Ngakho-ke, izindlela zabo wokuzingela, zizalela imikhuba hhayi okuningi waziwa. Bazijayeze kokukhulelwa yangaphakathi. Ukukhiqiza kabusha usebenzisa amaqanda. Phakathi nale nkathi, e ezikhiqiza amaqanda kowesifazane uwathole ngobuningi ne degree yentuthuko obuhlukahlukene. I avuthiwe kakhulu kuwona egqoke i-cornea.

Kuze kube ngasekuqaleni kwekhulu XX, ulwandle onogwaja yayiba yize kwezohwebo. Okokuqala, kunzima kakhulu ukuba kukhishwe. Futhi okwesibili, chimeras inyama kubhekwe engenakudliwa ngobubi bawo, futhi Akufani nsuku zonke. Nakuba, cishe, kubalulekile ukwazi ukupheka kahle. Kwezokwelapha, sisebenzisa amafutha akhishwa livers yabo. Futhi isetshenziswa uwoyela. Kodwa amaqanda yabo yayiwuhlobo real okwehla esiphundu.
