I-Starfish Ziyi-echinoderm ezingenakho ukuhamba kodwa nokho ziyizidalwa eziphilayo. Ziyinqaba futhi zihlala olwandle. Ujwayele ukukhuluma ngezinhlobo ezihlukahlukene de peces, lesi sihloko sikhethekile futhi sinelukuluku lokwazi. Lezi zilwane ziyafana futhi zihlobene nama-sea urchin nama-sea urchin. izipanji. Igama lesayensi yi-Asteroidea futhi singathola izinhlobo ezahlukahlukene esizobona kukho konke okuthunyelwe.
Ngabe ufuna ukufunda konke mayelana ne-starfish? Qhubeka ufunde ngoba le ndatshana ilayishwe imininingwane ebalulekile 🙂
Izici eziyinhloko
I-starfish yehlukile kwezinye izinhlobo ezinjengezinhlanzi esijwayele ukukhuluma nazo ngezindlela eziningi. Into yokuqala ukuthi azidingi izifuba zokuphefumula. Banembobo lapho beshintsha khona amagesi ukwethula umoya-mpilo oncibilikisiwe emanzini emzimbeni wakho.
Ngokungafani nezinye izilwane eziningi, zihlala isikhathi eside impela, zikwazi ukuhlala iminyaka engama-35 uma izimo zivuma. Ngokuya ngezimo nezinhlobo zezilwane, yizilwane ezingaba nesisindo esingafika ku-5 kg. Isikhumba saso si-prickly futhi senziwe ngengubo emelana kahle nokwakheka kwe-calcium carbonate. Ngenxa yale ngubo azinakwa futhi zingavikelwa ezilwaneni ezidla ezinye.
I-starfish inezitho ezi-5 ezizungeze umzimba ophakathi nendawo omiswe njengediski. Yilezi zilwane ezinokulinganisa kwamaphuzu amahlanu okusabalasa. Ezinye izinhlobo ezikhulisa isibalo semilenze zikwazi ukuba nezingalo ezingafika kwezingama-40.
Yize zingenakunyakaziswa ngoba i-calcium carbonate coating ayikuvumeli, zingasuka kwenye indawo ziye kwenye. Kunezinhlobo zezinhlobo okuthi, noma zingenakho ukunyakaza okuvezwe kakhulu, ziyakwazi ukuhambisa ezinye izitho. Ukuhamba bakhasa phansi ngoba abakwazi ukubhukuda. Izingalo zimbozwe ngezitho ezifana nezibopho nezinkomishi zokudonsa abazisebenzisayo ukukhipha umoya ngamandla futhi bakwazi ukuhamba kancane bawele phansi olwandle.
Ezincomeni zezingalo banezinzwa ezibasiza ukuthola, ukubona inani lokukhanya kukhona futhi yile ndlela abakuthola ngayo ukudla abakudingayo ukuze baphile.
Izinhlobo ze-starfish
I-Starfish yakhiwa yizinkulungwane zezinhlobo ezinezici ezahlukahlukene ngayinye yazo. Zisatshalaliswa emhlabeni wonke. Okudume kakhulu ngobuningi baso nangokusabalala kwabo emithonjeni yezindaba yilezo zinkanyezi eziyisihlanu zakudala ezihlomile. Njengoba sishilo ngaphambili, lokhu akwenzeki ngaso sonke isikhathi. Kungenzeka ukuthola izinhlobo zezinye izinhlobo zama-echinoderms anezingalo ezingafika kuma-5.
Manje sesizobona ezinye zezinhlobo ezaziwa kakhulu.
I-Brisingida
Kuyinto starfish ukuthi akhiwe phakathi kwezingalo eziyisithupha kuya kweziyi-6. Lolu hlobo lwe-starfish luqukethe imindeni eyisithupha nohlu lwezinkanyezi zasolwandle eziyi-16, yona leyo eyakhiwe ngezikhali.
I-Forcipulatide
Lolu hlobo lwakhiwe yizinhlobo ezingama-400 ezisatshalaliswa emindenini eyisi-6 yemikhakha engama-70. Isici sayo esiyinhloko ngukuthi sibe nama-pedicelar pedicels abonakalayo ebusweni bomzimba waso.
I-Notomyotide
Lolu hlobo lwenkanyezi lunezinhlobo ezingaba ngu-70 eziqukethwe emkhakheni ongaba yishumi nambili. Lezi zingalo ziguquguquka kalula kunalezo zezinkanyezi eziningi. Lokhu kuhamba kungenxa yokuthi banezibopho zemisipha ngaphakathi kobuso babo bangaphakathi obubavumela ukuba banyakaze futhi basize ekuhambeni kwabo kanye nezivinini zomoya oshiwo ngenhla.
IVelatida
Le starfish inomzimba oqinile onediski enkulu maphakathi nomzimba nokudangala okuncane. Kunezinhlobo ezingaphezu kuka-300 ze-velatida emikhakheni engama-25 nemindeni emi-5.
UValvatida
Yibo abaziwa kakhulu emhlabeni. Kunezinhlobo ezingama-700 ezinesizukulwane esingu-170 kanye nemindeni eyi-14. Yibo abadume kakhulu ngokuba nezingalo ezi-5.
Indawo yokuhlala nokudla
I-Starfish ihlala cishe kuzo zonke izindawo zasolwandle. Basengozini yokungcola njengoba bebeka amanzi ngqo emzimbeni wakho ukuhlunga i-oksijeni encibilikile. Ngakho-ke, uma amanzi engcolisiwe bafa bedakiwe baminza.
Ezilwandle nasolwandle, lezi zilwane zakha ingxenye enkulu yemvelo ekhona. Zidlala indima ebalulekile nasolwandle nasemiphakathini ehlala kulo. Izindawo zokuhlala lapho singazithola khona yizilwandle, ugu olunamadwala, imibhede yezimila zasolwandle, izixhobo zamakhorali, utshani obusolwandle, amachibi olwandle kanye namabhodlela esihlabathi aze afike kumamitha ayi-9.000 obumnyama lapho kuhlala khona izinhlanzi ezithile zakwalasha.
Ngokuphathelene nokudla, i-starfish idla kakhulu kuma-mollusk njengamanye ama-oysters, iminenke kanye nama-clams. Ukuze bazondle banezinhlobo ezithile eziwumphumela wokuziphendukela kwazo nokuzivumelanisa nezimo. Lapho i-starfish isinamathisele umzimba wayo enyameni efuna ukuyifaka, inwebeka isisu sayo ngaphandle ngokukhipha ngomlomo wayo. Isisu sikhiqiza ama-enzyme akwazi ukwehlisa isisulu saso kuze kube yilapho simuncwa ngokuphelele. Lokhu kusiza ukudla ukuthi kuye ngqo esiswini futhi kungagaya kalula futhi ngokuphelele. Izidalwa ezincane ziyizisulu ezilula ze-starfish.
Ngokuphikisana nabo, izidalwa eziyinhloko zalezi echinoderms zingoshaka abanjengo ushaka omhlophe o ushaka wenkunzi, imisebe ye-manta, ezinye izinhlanzi ezinkulu zenkanyezi nezinye izinhlobo de peces.
Indlela Yokuphila
Ukuzivikela ezilwaneni ezidla ezinye zisebenzisa izindlela ezithile zokuzivikela njengesikhumba esiqinile nameva, ezinye zinemibala egqamile ebonakala inobuthi futhi ziyakwazi ukuzifihla phakathi kwezitshalo namakhorali noma zilahlekelwe yingalo ukuze ziqhubeke ziphila.
Lezi zilwane aziwona umphakathi nezeEsikhundleni salokho, bahlala bodwa isikhathi esiningi sempilo yabo. Kwezinye izikhathi bangabonakala ndawonye nabanye ngezikhathi lapho kunokudla okuningi.
Ngiyethemba ukuthi ngalolu lwazi ungafunda kabanzi nge-starfish.
