I-red-spotted cat shark (Schroederichthys chilensis), eyaziwa nangokuthi yi-Chile spotted cat shark, ingeye-superorder of shark, class - fish cartilaginous.
Ukusatshalaliswa koshaka onamabala abomvu.
I-cat shark enamabala abomvu itholakala emanzini asogwini ukusuka enkabeni yePeru eningizimu yeChile kuya empumalanga yePacific Ocean. Lolu hlobo luvame kakhulu kulezi zindawo.
Izindawo zokuhlala zikati oshaka obomvu.
Oshaka bamakati ababomvu batholakala endaweni enamadwala amancane emaphethelweni eshalofu lasezwenikazi. Ukusatshalaliswa kwazo kubonakala kungesikhathi sonyaka, ezindaweni ezinamadwala entwasahlobo, ehlobo nasekwindla, nasebusika emanzini ajulile olwandle. Kukholakala ukuthi lokhu kuhamba kwenzeka ngenxa yesikhathi esinamandla ebusika. Oshaka bekati ababomvu bavame ukuhlala emanzini asukela kumitha elilodwa kuya kumashumi amahlanu ukujula. Endaweni engasogwini, ekujuleni kwamamitha ayi-8 kuye kwangama-15 ehlobo nasuka ku-15 kuye ku-100 m ebusika.
Izimpawu zangaphandle zikashaka onamabala abomvu.
Oshaka bamakati abomvu ababomvu bakhula bafike kubukhulu obukhulu obungu-66 cm.Ubude bomzimba besifazane busuka ku-52 kuye ku-54 cm, kanti ubude besilisa busuka ku-42 kuye ku-46 cm.
Lezi zinhlobo zikashaka zinomzimba obushelelezi ohlangene, ojwayelekile womndeni wonke.
Banemigqa emihlanu ye-branchial, enovulo lwesihlanu lwe-branchial olungaphezulu kwamaphiko we-pectoral. Zinamaphiko amabili emhlane engemuva, ngaphandle kokuphamba, umphetho wokuqala we-dorsal ongaphezulu kwesifunda se-pelvic. Cishe akukho ukugoba okuphezulu emsileni.
Oshaka bamakati ababomvu babanombala onsundu ngokubomvu ngoku nsundu nangesisu esimhlophe esakhilimu. Banamabala amnyama ezansi komzimba kanye nezimpawu ezimnyama ezibomvu ezindaweni ezimhlophe.
Inani lamazinyo emadodeni livamise ukuba likhulu kunama-valve ambalwa, okukholelwa ukuthi ayadingeka "ekubizeni" abesifazane ngesikhathi "sokuqomisana".
Ukukhiqizwa kabusha kukati oshaka obomvu.
Oshaka bamakati abomvu babonakala ngokuzala ngezikhathi ezithile, ngamaqembu abantu bobulili obuhlukile avela ebusika, entwasahlobo nasehlobo eduze kwaseSan Antonio, eChile, eFarinha nase-Ojeda. Kodwa-ke, kwezinye izimo, oshaka besifazane babeka amaqanda abekiwe unyaka wonke.
Oshaka be-feline shark abanamabala abomvu banomkhuba othile wokuqomisana ngesikhathi sokukhwelana, lapho owesilisa eluma khona owesifazane ngenkathi efuthisa amaqanda.
Lo shark u-oviparous, futhi amaqanda avundisiwe avame ukukhula ku-oviduct. Zivalelwe ku-capsule, i-capsule ngayinye imvamisa iqukethe amaqanda amabili. Imibungu iyakhula ngenxa yezinqolobane ezigciniwe. Oshaka abancane bavela ngobude obungu-14 cm, bangamakhophi amancane oshaka abadala futhi ngokushesha bazimele, babheke emanzini ajulile. Amafry kukholakala ukuthi abhukuda emanzini ajulile ukugwema ukudliwa endaweni engaphansi futhi abuyele endaweni yawo lapho esekhulile. Ngakho-ke, kunokuhlukaniswa kwendawo phakathi kwabantu abadala nentsha, oshaka abakhulayo. Oshaka bekati ababomvu bakhula ngokushesha, kepha iminyaka lapho uthomba ayaziwa. Isikhathi sokuphila endle asikasungulwa.
Ukuziphatha kukati oshaka obomvu.
Oshaka bamakati abomvu ababomvu bayizinhlanzi ezihlala zodwa. Zihamba ebusuku, zihlala emigedeni nasemigodini emini bese ziphuma ebusuku ziyokondla. Ezinyangeni zasebusika zehlela emanzini ajulile, phakathi nonyaka osele zihamba emaphethelweni eshalofu lamazwekazi. Le nhlangano kukholakala ukuthi ihlotshaniswa nemisinga enamandla ngalesi sikhathi sonyaka. Oshaka abaziwa ngokubomvu, njengabanye oshaka abaningi bomndeni wakwaScyliorhinidae, sebenomqondo wokuhogela nowokuthola ugesi, ngosizo lwazo izinhlanzi ezizwa imizwa kagesi ekhishwa ezinye izilwane, futhi ziziqondise ngamandla kazibuthe.
Oshaka bekati baqanjwa ngamagama abo ngokuba khona komfundi oqondile we-oval weso. Banombono omuhle ngisho nasekukhanyeni okuncane.
Ukondla ushaka onamabala abomvu.
Oshaka bamakati abomvu ababomvu yizilwane ezidla ezinye, ezidla izinto eziphilayo ezahlukahlukene ezincane ezingezansi. Ukudla kwabo okuyinhloko izinkalankala nezimfanzi. Futhi badla izinhlobo eziningana zamanye ama-crustaceans, kanye nezinhlanzi, ulwelwe, nezikelemu ze-polychaete.
Indima ye-ecosystem katsaka onebala elibomvu.
Oshaka bamakati ababomvu babalulekile ekuxhumaneni kokudla endaweni yabo yezinto eziphilayo. Lezi zidalwa zilawula ubuningi bezinto eziphilayo kubantu be-benthic endaweni engasogwini.
Oshaka bangabathwali bezinambuzane eziningana, kufaka phakathi izingwe, ama-trypanosomes. Ama-Trypanosomes akhubaza igazi lezinhlanzi futhi asebenzise imizimba yawo njengomphathi omkhulu.
Okusho umuntu.
Oshaka bamakati ababomvu babhekwa njengocwaningo lwesayensi olwenziwa emalabhorethri, babanjelwa izinhloso zocwaningo, ngakho-ke ukubanjwa kwalezi zinhlanzi kungathinta usayizi wabantu abancane, bendawo. Kepha ziyingozi ezindaweni zokudoba ezimboni eChile nasePeru, njengoba zondla ama-crustaceans, abaluleke kakhulu kwezomnotho kwamanye amazwe.
Isimo sokonga soshaka onamabala abomvu.
Kunemininingwane emincane kakhulu ngenani labantu kanye nezinsongo kulezi zinhlobo zokufaka ushaka onamabala abomvu kuLuhlu Olubomvu. Zibanjwa njengezinhlanzi ezibanjwa ngokungazelelwe ezindaweni zokudoba ezisogwini, ezansi nezide. Akwaziwa noma ngabe oshaka bamakati abomvu babonakala besengozini noma besengozini. Ngakho-ke, akukho zinyathelo zokongiwa ezisetshenziswayo kubo.
