Seahorse

Olwandle olubomvu

El I-Seahorse Ingesinye sezilwane ezihlaba umxhwele kakhulu esingazithola olwandle. Ngenxa yokubukeka kwayo kukhumbuza kakhulu amahhashi, ngoba anekhanda elifana ncamashi nalelo lama-equines. Kunezinhlobonhlobo zezinhlobo, kepha zonke zinento eyodwa ezifanayo: zidonsela ukunaka kwabantu abazama ukuhlola indawo abahlala kuyo.

Ngakho-ke, kulokhu siphume kancane kokujwayelekile ukukwethula kulezi zilwane ezinhle zasemanzini.

Lunjani ulwandle lolwandle?

Umzimba

Isifanekiso se-Hippocampus histrix

Ama-protagonists ethu yizilwane ezingafani ngalutho nezinye izinhlanzi. Bafinyelela kubude obuphakathi kuka-14mm kuye ku-29cm. Umzimba wakhe umbozwe yizembatho zamapuleti noma amasongo omthethosisekelo wamathambo. Ukuma kwayo kuhlala kumile. Zisuka kwenye indawo ziye kwenye zibonga i-dorsal fin yazo, etholakala engxenyeni engezansi engemuva, eduze kakhulu nomsila. Yize beyinyakazisa cishe izikhathi ezintathu nengxenye ngomzuzwana, bavame ukuba nenkinga enkulu yokufika lapho beya khona. Bazuza ukufuduswa okumi mpo ngokulungisa ivolumu yomoya kuzibhuku zokubhukuda nangokusebenzisa amaphiko we-pectoral.

Umsila wayo uyisethenjwa, okusho ukuthi zingabambelela kuma-coral nasezitshalweni zasemanzini, ngaleyo ndlela zivimbele imisinga yolwandle ukuthi ingayihambisi kakhulu. Yini enye, zilingisa, okungukuthi, bangashintsha imibala yemizimba yabo ukuze bahlangane ne-macroalgae endaweni yabo. Lelisu libalulekile ukuze baphile, ngoba amalwandle asolwandle asebenza njengokudla kwezinkalankala, i-tuna, i-goldfish nezinyoni zasolwandle.

Ukuphefumula

Njengazo zonke izinto eziphilayo, badinga ukuphefumula futhi, njengezinhlanzi, bakwenza ngokusebenzisa ama-gill. Ngenxa yalezi zitho, zingakhipha umoya-mpilo oncibilikiswe emanzini bese zikhiphela i-carbon dioxide emvelweni.

Ukuxhumana nabanye ontanga

Yize kungahle kungabonakali kunje, ama-seahorses ayizilwane ezihlala emanzini. Amaqembu amancane atholakala kalula eduze kwamakhorali. Ukuxhumana, bangela uhlobo lokuchofoza umsindo ngokunyakaza okusheshayo kwekhanda labo, ngaleyo ndlela uxubha ingxenye yogebhezi ngengxenye yamathambo ayo aphezulu angaphandle. Kanye ngonyaka, lapho izinga lokushisa lamanzi likhuphuka, zijoyina abangane bazo ngokufaka imisila yazo imizuzu engu-15 kuya kwengu-20.

I-Hippocampus esiswini isisu

Indoda idonsa uketshezi lwayo lwesidoda ngaphandle, kuthi lapho amaqanda engena esikhwameni sowesilisa, esibizwa ngokuthi i-marsupium, ayavuthwa. Lapho bangakhula bevikelwe kahle kusuka ezinsukwini eziyishumi kuya emavikini ayisithupha, kuya ngohlobo nezinhlobo zokushisa kolwandle. Ngemuva kwalesi sikhathi, owesilisa uyayidedela iphume, enze isivumelwano ngomzimba wakhe ukufaka ingcindezi bese eyadedela, into ezogcina yenze amahora amaningi. "Ukubeletha" ngakho-ke kungakhathaza umzali, ngoba bangaba nentsha ephakathi kwabayishumi kuya kwabangaphezu kuka-10.

IzinganeUma seziphumile, azikho ngaphezu kwamamilimitha ayi-7-11 ubude. Kuze kufinyelele usayizi wabantu abadala, bazongena baphume esikhwameni kuya ngokuthi kunengozi noma cha phesheya.

Izinhlobo zezinhlobo

Uhlobo lohlobo lwasolwandle, iHippocampus, lakhiwe yizinhlobo ezingama-57. Ezinye zazo zikhona:

IHippocampus esiswini

I-Seahorse eyaziwa njenge-Hippocampus abdominalis

Eyaziwa njenge-seahorse yolwandle enamabhodwe noma ulwandle olunamabhande amakhulu, ulwandle olude olungu-35cm. Ihlala ngasogwini lwaseNew Zealand nase-Australia, lapho idla khona ama-crustaceans nezinye izilwane ezincane ezihlala phakathi kwe-algae.

IHippocampus capensis

Isibonelo seHippocampus capensis

Yizinhlobo ezisongelwa kakhulu. Zingafinyelela ekuphakameni okuphelele okungu-12cm, ekubeni ezeduna ziqinile futhi zinde kunezabesifazane.

IHippocampus severnsi

Isibonelo seHippocampus severnsi

Kuyinto yezinhlobo ezaqala ukubonakala e-Indonesia ngonyaka ka-2008. Ihlala emanzini asezindaweni ezishisayo oLwandlekazi iPacific, e-Australia, eFiji, eJapane, ePapua New Guinea naseSolomon Islands.

Uhlala kuphi ulwandle?

Amakhorali ase-Afrika

Ama-seahorses atholakala emanzini afudumele, ikakhulukazi asezindaweni ezishisayo, phakathi kuka-0 no-2543m. Ububanzi bokushisa buhamba phakathi kuka-3,04 no-28,4ºC. Ukuze, zikhula kahle ezindaweni ezishisayo nezishubile, ogwini loLwandle i-Atlantic, kufaka phakathi uLwandle iMedithera, njengase-Indo-Pacific, kusukela ogwini lwaseMpumalanga Afrika kuya enkabeni yePacific, kuhlanganise noLwandle Olubomvu.

Ngeshwa, kuze kube namuhla bayizilwane ezisengozini yokuqothulwa, futhi ukuhweba kwalo kulawulwa yiCITES (Convention on International Trade in Endangered Species of Wild Fauna and Flora). Amathani olwandle abanjwa minyaka yonke e-Asia kuphela ukuze asetshenziswe ekwelashweni kwendabuko. Lapho, kukholelwa ukuthi banezinto zokwelapha.

Ngokufanayo, i-International Union for Conservation of Nature (IUCN), ubhale izinhlobo eziningi zohlobo lo njengabantu abasengozini, kanti abanye bathi "basengozini enkulu", njenge IHippocampus capensis, ehlala echwebeni lomfula iKnysna kuphela nakweminye imilambo emithathu esogwini oluseningizimu yeNingizimu Afrika.

Ukuyivikela ekunyamalaleni, kwakhiwa izindawo zokuhlala ezingekho emthethweni, njengoba kwenzeka esizalweni esisodwa somfula iKnysna.

Uyithandile le ndatshana emayelana nolwandle?
