Nyama zimenezi anthu pafupifupi onse m'nyanja ndi m'nyanja za dziko lapansi, madzi amene ndi mchere zokwanira. Nyenyezi savutika madzi desalinated, iwo sakupezeka mu Nyanja ya Azov ndi Nyanja ya Caspian.

Cheza nyama akhoza kukhala pa 4 ndi 50, masaizi osiyanasiyana kuchokera masentimita angapo mita. moyo akuti ndi zaka 20.

Pa anthu m'madzi alibe ubongo, koma aliyense ray pamenepo maso. Mitembo ya tizilombo kapena nkhanu amafanana bwino kusiyanitsa kuwala ndi mthunzi. maso ambiri amathandiza nyama kusaka bwinobwino.

Kupuma nyenyezi pafupifupi kudzera pakhungu, kotero ndikofunika zokwanira mpweya mu madzi. Ngakhale ena mitundu mwina anthu nyanja kwambiri yabwino.

mbali structural

N'zochititsa chidwi, monga mtundu ngati kudya starfish. Biology akunena nawo kalasi ya echinoderm nyama zonse zopanda mafupa. Starfish mulibe magazi yokha. M'malo mwake, mtima wa nyenyezi amawapopa kudzera zotengera za madzi nyanja, wolemera mu micronutrients ena. Ikukoka Madzi chimadzaza maselo a chinyama, komanso kudzera mwa jekeseni madzi mu umodzi kapena malo ena amapanga nyenyezi kusuntha.

Starfish ndi cheza chithunzi cha dongosolo la mafupa a - m'chigawo chapakati cha zinyalala kunyezimira. Mafupa a nyanja kukongola zachilendo. Iwo wapangidwa ndi calcite ndipo akufotokozera mkati nyenyezi yaing'ono ku maselo pafupifupi angapo Mbali yokhala ngati. Kodi ndi mmene kudya starfish, makamaka zimadalira maonekedwe a dongosolo lawo.

echinoderms awa ali pa tentacles awo pedicellariae wapadera mu mawonekedwe a mbano pa chilichonse nsonga ya protuberance lapansi. Ndi thandizo lawo, nyenyezi kusaka ndi kuyeretsa khungu la yatsekera pakati pa singano zinyalala.

msaki kuchenjerera

Anthu ambiri amadabwa mmene kudya starfish. Mwachidule za dongosolo la kachitidwe kawo m'mimba angapezeke m'munsimu. Izi kukongola zidzasintha munthu chithunzithunzi cha chitetezo wangwiro. Ndipotu, iwo ndi ogwirira m'madzi, ndi voracious ndi losakhutiritsidwa. kokha drawback awo - pang'onopang'ono liwiro. Choncho amakonda muzidzamuchitirabe - Nsomba zipolopolo. Ndi zosangalatsa starfish chakudya pa chisa, si mantha kudya kanyama, nkhaka nyanja, ndipo ngakhale mosadziwa anasambira kwambiri ndi nsomba.

Popeza kuti starfish ndi pafupifupi m'mimba, mmodzi amene akhoza kuyatsa mkati mpaka kunja. Osasamalira nsembe anamvetsetsa pedicellariae imafalikira kuti patsekeke m'kamwa pakati cheza, ndiye, ngati khoka, amaponyera m'mimba. Kenako, msaki akhoza kusiya nyama ndi kupukusa pang'onopang'ono. Ena nthawi nsomba anakoka ndi wakupha wake, koma wovulalayo sunapewe. Chirichonse wakudya starfish, mosavuta digested mmimba mwake.

Chinachake mosiyana atadza iye limalephera: pang'onopang'ono kubwera kwa mbale chokondweretsa, kupindika padziko chipolopolo ndi kuwala kwake, kuwayika pakamwa patsogolo pa chipolopolo kudula n'kuyamba kulikankhira lamba wa pamimba.

Izo ziyenera kuonekera osachepera kudula pang'ono, kamodzi anakankhira m'mimba akunja. Tsopano m'madzi Gourmet mwakachetechete chosinkhasinkha lakuya makamu, kupanga mollusk mu mankhwala odzola ngati. Chotero tsoka adzakhumudwa nsembe iliyonse kudya, kaya zoyendetsedwa starfish sikalopu kapena nsomba zina zing'onozing'ono.

Features ya kapangidwe ka dongosolo m'mimba

Pa chilombo, pali palibe zipangizo kuti amvetse nyama. Pakamwa atazunguliridwa ndi mlomo annular olumikizidwa kwa m'mimba. thupi ili amatenga mkati lonse la chimbale ndipo kwambiri kusintha. Wokwanira mpata wa 0,1 mamilimita kudutsa mavavu chipolopolo. The mbali aboral malo amatsegula yopapatiza lalifupi matumbo, akuthamanga kuchokera m'mimba. Kodi wadya starfish, izo kumadalira kapangidwe osaka dongosolo m'mimba.

Chikondi nyenyezi pansi pa nyanja

Ambiri starfish - mwamuna ndi mkazi. Pa nthawi ya lovemaking anthu pamodzi zambiri amasiya kusaka amakakamizidwa kusala. Koma si oopsa, chifukwa limodzi la m'mimba ya schemers zimenezi pasadakhale amakonda kusiya kaye zakudya pa nthawi yonse ya mating.

Kugonana zopangitsa nyenyezi pafupi ndi matabwa m'munsi. Pamene mating anthu mwamuna ndi mkazi kulumikiza matabwa, monga ngati merging mu kukumbatirana wofatsa. Nthawi zambiri, caviar ndi maselo chiwalo chachimuna kugwera mu madzi nyanja, pamene umuna zimachitika.

Ngati kuchepa kwa anthu ena, nyenyezi akhoza kusintha pansi kukhalabe anthu mu dera.

Caviar anthu a nyanja zambiri wapatsidwa yokha mpaka kuswa. Koma ena nyenyezi ndi wachikondi makolo: amavala pa misana yawo mazira kenako mphutsi. Mitundu ina ya nyenyezi nyanja ili pa mating pa nsana pali matumba wapadera kwa mazira, ndasambitsa bwino ndi madzi. Pali zingakhale pa kholo maonekedwe a mphutsi a.

Wofalitsa ndi magawano

Ndithu zapadera luso starfish - kuswana magawano unsembe. Luso kukula yokha latsopano dzanja-ray alipo pafupifupi nyama zonse mitundu. Star, anamvetsetsa chilombo cha mtengo akhoza kupeta izo monga mchira buluzi a. Ndipo patapita kanthawi kukula ina.

Komanso, ngati tipitiriza pamodzi ndi mzere wa tinthu ka chigawo chapakati cha izo patapita nthawi zina kukula starfish wathunthu. Choncho, kuwononga ogwirira awa, kusema zigawo, sikutheka.

Mwa iwo amene amadya starfish mu chikhalidwe, chogwidwa ndi mbalame zikuluzikulu. M'mphepete mwa nyanja ofunda, iwo amawachita gulls. Mu Pacific, nyenyezi si mantha kudya oseketsa otters nyanja.

Chilombo zoipa m'madzi m'minda nkhono ndi scallops - zimene amadya starfish. Kuyesa kupha nyama, akuigwiritsa iwo mu zidutswa, zachititsa kuti ndi kuchuluka. Kenako anayamba kumenyana nawo, kubweretsa nyenyezi pa gombe ndi kuwotcherera mu madzi otentha. Koma ntchito mabwinja adawoneka paliponse. Pakhala anayesa ku manyowa nyama, tizirombo imodzi kufumbwa. Koma kufalitsidwa lonse ndi njira si analandira.
