Yesigcawu Sea - abemi obufihlakeleyo ezinzulwini

yesigcawu Sea ibizwe izilwanyana mnogokolenchatymi. Baya kuba iklasi ka Chelicerata, uhlobo ezi zidalwa - Arthropods. Kwakhona elamkelekileyo, ukuhlelwa apho ibinzana elithi "Chelicerata" lichazwa njenge okuninzi apho elwandle izigcawu kwiklasi eyahlukileyo. Kukho iinketho ezininzi igama ngonzululwazi sokuba olu didi - Pantopody, Piknogonidy kunye nabanye.

Abanye ulwazi jikelele

Le mbono "spider yolwandle" iquka iintlobo ezingaphezu kwe-1,300 ezahlukeneyo ezininzi iintsapho. Bona bahlala kweelwandle ehlabathini lonke. Dibana marine arthropods kuba kubunzulu obahlukeneyo. Ezinye iintlobo bakhetha kwamaza (icandelo baphumelele elunxwemeni) asezantsi, omnye uhamba aye abyssal (zone enzulu). Amanzi anetyuwa kwaye amtyuba Mnogokolenchatye kakhulu kuxhaphake kakhulu kunokuba kulwandle brak emhlabeni. Kwiindawo eziselunxwemeni, izigcawu ii-e-ematyholweni ezimdaka kunye phezu komhlaba.

Deep-ulwandle kunye neentlobo Littoral of zezigcawu kwakhona umahluko isakhiwo umzimba, kwaye ubukhulu. Kwiingcamba ezinzulu yesigcawu amanzi ulwandle mkhulu, kuba ixesha elide kakhulu yaye imilenze ukubhitya, nto leyo enokubadla imali bude. Ezi zixhobo ukunciphisa izinga echibini. Spider ayenziwanga nje ezidadayo, ngokungathi edada emanzini. Ukuze iye kuhlala ezantsi, oko Ngokomzi ngokwaneleyo ukuze babeke phantsi amalungu abo omzimba elide phantsi Taurus.

ifomu compact Coastal. Zozine ziyatyeba kwaye elifutshane, kodwa ibekwe amaqhuma yaye zakhe zokutyhomfa eziyimfuneko ekuzingeleni kunye nokhuseleko.

iimpawu zezakhiwo

Nawuphi zezigcawu ulwandle, zinzulu-ulwandle kunye elunxwemeni, isakhiwo eqhelekileyo. Umzimba wahlulwe ezimbini Tagme (isebe). igama labo - abamnkela non-abamnkela prosoma opisoma. Kuba prosoma zezindlu iimpawu okanye idiskhi-ezimile.

Umboko elwandle zezigcawu nemilenze wayifulela kunye Ulobuza chitinous. Kukho iyantlukwano kule cephalothorax kunye nesisu (a oludala). Xa cephalothorax ukusuka amacandelo-7 ukuya ku-9 4 ezinyibilikiswe kunye. ingxenye tho ye cephalothorax kuthiwa ingxenye intloko. Ezi ziqwempu ezishiyekileyo ukuze nokuba edidekile, kwaye dissected. Front intloko umboko kwicandelo le zezindlu okanye imilo ovoid. On iindawo zisecaleni buti ayinakutshintshwa ngambini amalungu omzimba: helifory kunye palps. Kwicala ventral kwintloko yesebe yafumana isibini sesithathu amalungu omzimba (imilenze desyatichlenikovye oviparous). Enye iimpawu noshowo izigcawu elwandle 3 phambi izibini imilenze musa ukufikelela emhlabeni, yaye musa inxaxheba ukuhamba.

Ukuhamba imilenze zesigcawu ulwandle ezikhuselekileyo namasebe yokwayama kuyo intloko ingxenye yomzimba. Amaninzi ke 4 ezibini, kodwa abanye abameli - 5-6 bengababini.

inkqubo alimentary

spider Marine liye inkqubo zokwetyisa ngendlela ngokusebenzisa ityhubhu neenkalo kancinane ukusuka diverticula. Diverticulum kulo mzekelo - yinkqubo ethunjini ukuba ingena ekuphelwa kuyo kumjikelo ngamnye. Ekugayeni ezi arthropods zidityanisiwe. Sabiwe kunye nefomu esiswini kunye intracellular.

pheko

Kulula ukuba athelekelele into yesigcawu ifidi zaselwandle. Uninzi nazo - ngamarhamncwa. Kwizidlo kunye ezingenamqolo amavila amavila. Le ingaba polychaetes, bryozoans, ciliates, anemones, kunye coelenterates golovozhabernye izilwanyana, echinoderms ezizinkwenkwezi encinane. Mining yabamba iinzipho kwi heliforah. Kwakhona kuza off kunye amaqhekeza ukutya emlonyeni wakhe.

megalomania

Hayi kudala kumanzi Antarctic kwafunyanwa spider ulwandle ingxilimbela. Ngokufundisisa ngamnye, abaphengululi arhola ingqalelo kwizinto ezenzeka twisiseka, ekuthiwa gigantism ezibandayo. Kuba abathile, njengokuba sizathu kodwa ayaziwa, amanzi womkhenkce Antarctica abuye iintlobo eziqhelekileyo izigcawu yolwandle kwi-Anaki. Mhlawumbi inoxanduva ukukhula eziphuculweyo ioksijini, nto leyo iqulethwe ngamanzi abandayo kunokuba eshushu.

Kuye kwafunyaniswa ukuba gigantomania kumanzi Arctic andimvumeli izigcawu kuphela, kodwa ezinye molluscs, intlanzi kunye echinoderms. Uphenyo luyaqhubeka.

"Ezizinkwenkwezi kunye Spider"

Ucinga ukuba siza kuqhubeka ukuxoxa isakhiwo kunye nobomi izilwanyana zasemanzini? Kodwa wena engalunganga! Kweli candelo siza sithethe ngale ncwadi emnandi, ezichaza siseko impumelelo kwiinkampani ezahlukeneyo kunye nemibutho. Ezinye zazo zemveli, efana nezigcawu: iinyawo zabo ezikhula isiqu, intloko kunye namehlo. Angasebenza, ukulahlekelwa yinxalenye umlenze okanye anqunyulwe amehlo akhe, kodwa wemka ngaphandle intloko - ukufa.

Enye into korale, umzimba wakhe ikhangeleka zesiqhelo nangona, kodwa imisebenzi ezahlukeneyo kakhulu: intloko ingqondo kwesilwanyana ayikho kwaphela, kwaye imizimba eziphambili aphindaphindwe lomzimba nganye. Ngaphezu koko, ukuba inkwenkwezi Wanqumla lomzimba, iza kubuyiselwa. Nokuba xa sigeca ulwandle ezintle lwagabuka eziliqela, ukuba akayi kufa, yaye emva kwethutyana iihafu babe izilwanyana ezizimeleyo. Enyanisweni, umzekelo esi silwanyana esisodwa ngazo iinkampani asebenza uthungelwano efanayo zokwabela abaphantsi amagunya.

Le ncwadi "ezizinkwenkwezi kunye Spider" - umzekelo ocacileyo we yokuba yonke kwindalo unengqiqo, yaye uninzi imithetho uphuhliso luncedo ukuba isicelo kwezinye iinkalo zezinto ezenziwa luluntu.
