Kanjani futhi yini ukudla starfish: izici, izincazelo kanye namaqiniso ezithakazelisayo

Echinoderms izilwane, okuyinto zihlanganisa starfish, - abameleli iqembu ekhetheke kakhulu. Ababheki noma ubani. Lezi zilwanyana zasolwandle zibangele okuningi imibuzo, phakathi okuyinto Sinesithakazelo esikhethekile yilezi ezilandelayo: "Njengoba i-starfish odla?", "Kuze whom limelela usongo ofayo?".

Izinkanyezi ogwini

Lezi umhlobiso olwandle okungavamile ezikhona kule planethi isikhathi eside. Bavele iminyaka eyizigidi ezingu-450 edlule. Ukwabela kuze kufinyelele 1600 izinhlobo izinkanyezi. Lezi zilwane akha cishe zonke izilwandle nakho izilwandle zomhlaba, amanzi okuyinto okunosawoti ngokwanele. Izinkanyezi ababuzwa amanzi desalinated, basuke ayitholakalanga oLwandle Azov futhi yoLwandle iCaspian.

Rays ezilwaneni kungaba kusuka 4 kuya 50, amasayizi isukela ngamasentimitha ambalwa ukuthi imitha. ukuphila Ithemu Uneminyaka ecishe ibe u-20.

Ngo abakhileyo zasolwandle ungenalo zobuchopho, kodwa zonke ray kukhona amehlo. Izidumbu zabantu abangu-izinambuzane noma ezinamagobolondo ziyafana ukuhlukanisa kahle ukukhanya nasethunzini. Amehlo abantu abaningi kusiza izilwane yokuzingela ngempumelelo.

Breathe izinkanyezi cishe ngesikhumba, ngakho-ke mpilo obalulekile ngokwanele emanzini. Nakuba ezinye izinhlobo zawo zingase abahlala olwandle olujulile ehloniphekile.

izici kwesakhiwo

Ngokuthakazelisayo, njengoba zohlobo sengathi uma udla starfish. Biology libhekisela kubo ekilasini echinoderm ezilwane ezingenamgogodla. Starfish akudingeki igazi uqobo. Kunalokho, inhliziyo inkanyezi akhishwa ngokusebenzisa izitsha ngamanzi olwandle, ecebile micronutrients ezithile. Ukuphampa amanzi hhayi kuphela igcwalisa amaseli sesilwane, kodwa futhi esebenzisa umjovo ketshezi elilodwa noma kwenye indawo kwenza hambisa inkanyezi.

Starfish babe idayagramu emisebeni ye isakhiwo lwamathambo - ngumgogodla imfucuza-reyi. Amathambo ulwandle ubuhle engavamile. It yakhiwa calcite futhi ithuthukisa ngaphakathi izinkanyezi encane evela amaseli cishe eziningana calcareous. Yini nokuthi ukudla starfish, ixhomeke timphawu tesakhiwo yabo.

Lezi echinoderms ube ku tentacles yabo pedicellariae ekhethekile ngesimo nezizenze ngesikhathi ichopho protuberance ngamunye. Ngosizo lwabo, ukuzingelwa inkanyezi nokuhlanza kanye isikhumba sabo avimbekile phakathi izinaliti udoti.

yiphisi

Abantu abaningi bayazibuza kanjani ukudla starfish. Kafushane mayelana isakhiwo uhlelo lwabo wokugaya ukudla ingatholakala ngezansi. Lezi ubuhle emangalisa kunikeze umuzwa wokulondeka ephelele. Eqinisweni, zingabantu izilwane ezidla ezinye izilwane zasolwandle, le elinganeliseki kanye ezinganeliseki. ethile yabo kuphela - ijubane elinensayo. Ngakho-ke uncamela namanje aphathe - imbaza amagobolondo. Ubumnandi starfish ekhasini ikamu, kuyinto engakwenqeni udle sea urchin, ulwandle yamakhukhamba, futhi ngisho engaqondile wahlamba sisondele kakhulu inhlanzi.

Iqiniso lokuthi starfish cishe amabili izisu, omunye ezingasetshenziswa ujike ngaphakathi ngaphandle. Abanganaki umhlatshelo pedicellariae waziqonda idluliselwa ngaphakathi komgodi lolukhulunywako imisebe isikhungo, khona-ke, sengathi net, Ufaka esiswini. Ngemva kwalokho, umzingeli ungakwazi ukudedela inyamazane futhi ingagayeka kancane. Esikhathini esithile ngisho izinhlanzi edonswa wesahlulelo sakhe, kodwa isisulu akaphunyuki. Konke Odla starfish, kugaywe ku esiswini yayo kalula.

Ngandlela-thile ngendlela ehlukile ifika yena eshona: kancane eza isidlo olumnandi, twist emhlabeni igobolondo nge emaphikweni alo obeka umlomo phambi igobolondo umqhewu nekucala push ngaphambili esigqokweni.

Kufanele kuvele okungenani umqhewu encane kuwo ngesikhathi esisodwa kwaphoqa esiswini yangaphandle. Manje gourmet zasolwandle buthule eziswini echibini aphethe, okwenza silwanyana e ketshezi jelly-like. uthola isiphetho esinjena balindelwe noma ikuphi ukuzidela kudliwa, kungakhathaliseki inikwa amandla yi-starfish i-scallop noma inhlanzi encane.

Izici isakhiwo wokugaya ukudla

Ngesikhathi Predator, azikho amadivayisi ukuze zikwazi ukubamba inyamazane. Umlomo lizungezwe lip annular exhunywe kwi esiswini. Lokhu umzimba kuthatha lonke ingaphakathi disc futhi nezimo kakhulu. Engingakusho igebe 0.1 mm ukuhlaba zingene valve igobolondo. Uhlangothi aboral isikhungo kuvula ungumthombo ongumngcingo wamathumbu esifushane, egijima kusukela esiswini. Yini udla starfish, ke kuncike kakhulu isakhiwo engavamile wokugaya ukudla.

Uthando izinkanyezi ekujuleni kolwandle

starfish Iningi - kwabobulili. Ngesikhathi lovemaking abantu ndawonye ukuze matasa ukuthi stop ukuzingela bephoqeleka ukuba okusheshayo. Kodwa-ke akubulali, ngoba kwelinye izisu lezi schemers kusengaphambili bavame ukuhlehlisa izakhi isikhathi kokuzalela.

Ubulili nezindlala izinkanyezi eduze imishayo isizinda. Lapho ngokumitha kwemihlambi ngaphakamisa abantu iduna nensikazi ukuxhuma imishayo, sengathi ukuhlanganisa ku ekusinganyeleni emnene. Ngokuvamile, nezibiliboco futhi ubulili amaseli besilisa awela emanzini olwandle, lapho kokukhulelwa senzeka.

Endabeni ka ukushoda abathile, inkanyezi Ungashintsha phansi ukuze silondoloze labantu endaweni ethile.

Caviar abakhileyo kolwandle ngokuvamile kunikezwa uqobo kuze ukuchamisela. Kodwa ezinye izinkanyezi sabazali abakhathalelayo: abazigqokayo ezinkalweni zabo amaqanda bese izibungu. Ngo uhlobo oluthile ulwandle izinkanyezi salokhu ngesikhathi ngokumitha kwemihlambi ngaphakamisa ngemuva kukhona izikhwama esikhethekile amaqanda, wageza kahle amanzi. Kukhona kungaba ngesikhathi umzali ukubukeka izibungu.

Lokusakaza ukwahlukana

Izimo zethu zihluke kakhulu okungavamile ikhono starfish - yokuzalanisa division ngendlela. Ikhono ukhule uqobo entsha isandla-ray ukhona cishe kuzo zonke izilwane kwalesi silwane. Star, wakuqonda okwakushiwo nomzingeli ugongolo kungaba zivuleka it like umsila isibankwa sika. Futhi emva kwesikhashana sikhule esisha.

Ngaphezu kwalokho, uma siqhubeka agudle ka nezinhlayiya elincane ngumgogodla ke emva kwesikhathi esithize ukuze ukhule ube starfish ephelele. Ngakho-ke, ukubhubhisa lezi ezizingelayo, uthathe izingxenye, akunakwenzeka.

Ubani besaba starfish

Izitha bale ekilasini kancane. Akekho ofuna ukuba lokudlela nge ameva ezinesihlungu sea nebozhitelnits. Izilwane bakwazi ukuchitha odorants ngaphezulu oxosha elinganeliseki ikakhulukazi uma ibona izilwane eziyingozi. Uma kwenzeka ingozi, inkanyezi bangase bambe ku udaka noma isihlabathi, ekubeni icishe ingabonakali nhlobo.

Phakathi kwabadla starfish ngokwemvelo, ubuswa izinyoni ezinkulu ulwandle. Ogwini ezilwandle ezifudumele, bona yizisulu gull. Esikhathini Pacific, lenkanyezi engakwenqeni udle ezihlekisayo ulwandle imithini.

Predator umonakalo emasimini kwamanzi oyster futhi scallop - kulokho akudlayo starfish. Imizamo ukubulala izilwane, ukugawulwa zibe izicucu, baye kwaholela nokwanda kwenani labantu. Khona-ke waqala ukulwa nawo, ngokuletha izinkanyezi ogwini futhi Welding ngamanzi abilayo. Kodwa ukusebenzisa lezi zinsalela uvele ndawo. Sekube imizamo eyenziwe kusukela umquba wezilwane, izinambuzane kanyekanye oxosha. Kodwa ukusakazwa futhi indlela ingemukelwa.
