izicabucabu Sea ngokuvamile ebizwa izilwane mnogokolenchatymi. Bangabakhe ekilasini Chelicerata, uhlobo lezi zidalwa - eyisinambuzane. Futhi amukeleka is ngezigaba okuyiwona elithi "Chelicerata" uchazwa ngokuthi subtype kuyiphi ulwandle Izicabucabu esihlukile. Kunezindlela eziningana ongakhetha kuzona ngenxa yegama esingokwesayensi salo ekilasini - Pantopody, Piknogonidy nabanye.

Olunye ulwazi jikelele

Umqondo "ulwandle spider" kuhlanganisa izinhlobo ezahlukene eziningi imikhaya engaphezu kuka-1,300. Bona bahlala izilwandle emhlabeni wonke. Hlangana zasolwandle eyisinambuzane kungaba ekujuleni ezahlukene. Ezinye izinhlobo zawo zithanda aphansi intertidal (isigaba olwandle ogwini), omunye uhamba ngomnyama aye abyssal (zone ezijulile). I anosawoti brackish amanzi Mnogokolenchatye zivamile kakhulu ukwedlula e brackish kwezilwandle uma uya phakathi nezwe. Ezindaweni ezisogwini, le izicabucabu kuthiwa azinze ulwelwe amahlozi kanye emhlabathini.

Ekujuleni kolwandle nezinhlobo Littoral of izicabucabu nazo umehluko isakhiwo umzimba, futhi ngobukhulu. Esikhathini izingqimba ezijulile isicabucabu amanzi olwandle likhulu, kuba isikhathi eside futhi imilenze izacile, okungaba bude. La mathuluzi angakusiza ukwehlisa izinga echibini. Spider is hhayi nje elintantayo, sengathi sintanta emanzini. Ukuze kujule kuze phansi, kuba compact ngokwanele ukubeka phansi nemilenze zabo eside ngaphansi Taurus.

ifomu compact Coastal. Imilenze makhula futhi mfushane, kodwa itholakala uhlevane athuthukile kanye spikes kwakudingeka okuzingela futhi nokuvikelwa.

izici kwesakhiwo

Noma yimuphi spider kolwandle, futhi ekujuleni kolwandle zinhlobo ugu, isakhiwo ejwayelekile. Umzimba ihlukaniswe ezimbili Tagme (umnyango). Igama lazo - ihlukene futhi okungezona ihlukene prosoma opisoma. Ukuze prosoma isici cylindrical noma disc emise.

Wendlovu olwandle izicabucabu nemilenze ephansi futhi wambozwa cuticle chitinous. Kukhona ukwahlukana cephalothorax nesisu (a esingesihle). Ngo cephalothorax kusukela izingxenye 7 kuya 9 4 tho ndawonye. ingxenye tho we cephalothorax ubizwa ngokuthi ingxenye ikhanda. Amazenge ezisele kungenzeka noma tho, futhi dissected. ikhanda isiqu Front ingxenye cylindrical noma ukuma ovoid. On izingxenye lateral isiqu awashintsheki amabili namabhuzu nemilenze: helifory futhi palps. Ohlangothini ventral we inhloko yomnyango kuvikelwe umbhangqwana wesithathu nemilenze (imilenze desyatichlenikovye oviparous). Esinye sezici isakhi ulwandle izicabucabu ukuthi 3 phambi ngazimbili imilenze ungayifinyeleli phansi, futhi awahlanganyeli zihamba.

imilenze Ukuhamba sea spider kuvikelwe emagatsheni uhlangothi ikhanda ingxenye yomzimba. Ngokuvamile benjalo 4 ahamba ngamabili, kodwa abanye abameleli - 5-6 ngazimbili.

uhlelo alimentary

spider Marine has isimiso sokugaya ukudla bungene ngesimo a ngokusebenzisa tube kancane umahluko kusuka diverticula. Diverticulum kuleli cala - yinqubo esiswini ukuthi ingena umlenze ngamunye. Ukugaya lezi eyisinambuzane kuhlanganiswe. It is wabelane futhi ifomu besisu futhi intracellular.

abela

Kulula ukuqagela ukuthi zasolwandle okuphakelayo izicabucabu. Iningi lazo - kukhona eziyingozi. Ngo ukudla kwabo futhi sedentary ezingenamgogodla sedentary. Lokhu kungaba polychaetes, bryozoans, ciliates, anemones, futhi coelenterates golovozhabernye mollusk echinoderms starfish encane. Imayini labetibambile izimpiko ku heliforah. Futhi ukuza off futhi izingcezu ukudla emlonyeni wakhe.

megalomania

Hhayi kudala emanzini Antarctic giant ulwandle spider etholakele. Ngokufunda umuntu, abacwaningi yabhekisela mkhuba ongaqondakali, othiwa gigantism polar. Kwabanye, njengoba isizathu engakaziwa kuze kube manje, amanzi abanda njengeqhwa abanga-Antarctica uphendulela zinhlobo ajwayelekile ulwandle Izicabucabu Giants. Mhlawumbe obangela ukukhula sithuthukiswe oksijini, okuyinto equkethwe ngamanzi abandayo kuka e efudumele.

Kwatholakala ukuthi gigantomania emanzini Arctic ahlupheke hhayi izicabucabu kuphela, kodwa futhi abanye molluscs, ezinamagobolondo futhi echinoderms. Uphenyo luyaqhubeka.

"Starfish kanye Spider"

Ucabanga sizoqhubeka ukuxoxa isakhiwo nokuphila kwezilwane zasolwandle? Kodwa wena okungalungile!

Enye i-starfish into, umzimba wakhe ubukeka abavamile Nokho, kodwa kukhona nemisebenzi ehlukahlukene: inhloko nobuchopho sesilwane nhlobo nezidumbu main aphindaphindwe esitho ngamunye. Ngaphezu kwalokho, uma inkanyezi ukusika isitho somzimba, lizovuselelwa. Ngisho noma thina usike kolwandle enhle izingxenye eziningana, it is hhayi uzofa, futhi emva kwesikhashana neengcezu babe izilwane ezimele. Empeleni, isibonelo lokhu isilwane esiyingqayizivele ungase ucabangele izinkampani ezisebenza amanethiwekhi usabalalise efanayo.

Incwadi "Starfish kanye Spider" - sibonelo esigqamile yokuthi konke emvelweni uyacabangela, futhi eziningi imithetho ukuthuthukiswa kuwusizo ukusebenzisa kwezinye izindawo umsebenzi womuntu.
