Kukosha kweva crustaceans kuvanhu: zvakanaka uye zvisina kunaka. Zviratidzo zvekutengeserana uye zvipembenene zvisikwa

Chii chinorehwa nevaKristikasi kune vanhu? Zvakanaka uye zvisina kunaka. Mhinduro iyi ichava yega yechokwadi. Mushure mezvose, vanoshumira sechikafu chemhuka nevanhu, uye vamwewo chinhu chinobata hove. Asi mamwe magustaceans anotungamirira nzira yemararamiro ehupenyu uye vari pakati pemagetsi e helminths. Zvikamu zvekuita basa rinokosha, mararamiro uye zvakakosha zve arthropods idzi, tichakurukura munyaya yacho.

Rudzi rweva crustaceans

Vamiririri vemu subtype iyi arthropods zvakasiyana kwazvo. Izvi zvinotarisa kukosha kwemakristaceans kuvanhu: zvakanaka uye zvisina kunaka.

Pasinei neizvi, zvinowanzoonekwa zvechimiro chacho zvose. Crustaceans (iyo chinyorwa chiri pasi apa chinoratidzira mbambo) ine muviri unobatanidza cephalothorax uye mimba, iyo maimbirwo akabatanidzwa. Maviri maviri emakondohwe ari pamusoro. Nhengo dzemuviri dzinoputika ndezviputi, zvinyorwa ndezvipembenene zvakasvibirira.

Kurarama mumvura mitsva uye yemunyu, magustaceans vanodya zvose zvirimwa nemhuka duku.

Kanzera yakakwirira

Vamiririri vekirasi iyi ndeye crayfish. Nekugara kwavo, vanosarudza mvura yakachena yemvura uye yakasvibiswa mukati memhepo. Masikati vanoviga mumakomba, pasi pematombo nematanda. Pano vanobatwa nemurume. Nyamazikisi ane nyama inokosha yezvokudya. Nokuda kwechikonzero ichi, nhamba yevanhu vemarudzi mazhinji ichangobva kuderedzwa. A broad-mouthed crayfish yakatonyorwa muIndaneti Red Book.

Usiku, mapatya anobuda mumatende avo ndokuenda kunditsvaga. Izvi zvipenyu zvakanyatsokwaniswa omnivorous. Vanorara sehonye, mollusks, uye tadpoles. Uye vose vari vapenyu uye vakafa. Usaramba zvirwere zvekenza nemvura. Zvipfeko zvinowanikwa vanhu vanowanzotanga mumvura. Mukutapwa, crayfish inogona kudyiwa nechingwa, miriwo uye nyama.

Kunzvimbo dzakakosha dzekutengeserana dzinosanganisira lobster, crabs, lobsters uye shrimp. Munzvimbo dzakanakisisa dzekudya zvepasi pose, ndiro dzakabva kwavari dzinonyanya kudiwa, kunyange zvazvo kwete vose vanogona kuibhadhara.

Amphipods nemadhongi emvura ndezvokudya zvinokosha zvezvipenyu zvakawanda zvehova nemhuka dzegungwa. Kunyengedza, kugara muvhu rakaoma uye masango emasango, kuvasunungura, kuvegutsa nezvinhu zvakasikwa, kuvandudza mararamiro ezvokudya uye kupemha kwemiti.

Crawfish crayfish

Ivo vagari vemiti mitsva yemvura, iyo musoro wayo yakakwana zvakakwana kubva padanda. Izvi zvinosanganisira zviduku zvinokonzera daphnia, izvo zvinonziwo mvura fleas. Pamwe pamwe nezvimwe zvipenyu zvemvura, zvikamu zve plankton, iyo iri munzvimbo dzepamusoro dzegungwa.

Munhu anogamuchira daphnia pamagetsi ekudyisa hove. Inowanzoshandiswa kuwedzera marudzi akasiyana-siyana mumvura.

Nekubatsira kwa daphnia kuedza huwandu hwehutu hwemvura yakachena. Izvi zvipenyu zvakanyatsonaka kune zvinogadziriswa nemunyu. Dzinokonzera kupedzisira kwemajini. Mushure mokunge makustaceans achinyura kusvika pasi, kana kuti kusviba pasi.

Chikoro chemagwaro

Kukosha kwemakristaceans kuvanhu, zvose zvakanaka uye zvisina kunaka, kunowanikwawo mumapoka ejaya-bone boka. Daphniids uye cyclops yave achishandiswa kwenguva refu sechikafu chinokosha chekubereka hove dzevechidiki dzekutengesa. Parasitic cyprinids zvakarewo ma crustaceans. Vanodya paropa rehove, kazhinji zvichikonzera kukanganisa kwakanyanya kuvabati vehove.

Mhando dzakawanda dze cyclops dziri pakati pepakati pezvipembenene zvinoputika. Semuenzaniso, ribhoni yakawanda yei inoshanduka kuva maruva. Inonzi coracidium. Mhepo yakadaro yakaoma yakasununguka yakazara mumvura kusvikira inomedzwa nema crustaceans. Saka ivo vanova vekutanga vezvikwata zvezvipembenene. Wechipiri willy-nilly ndevehove dzinopisa dzinodya zvokudya zvekristaceans. Mumumuviri wemunhu, mhute inopinda mukushandiswa kwemafuta asina kuomeswa kana hove yakasvibirira. Ikoko vanobatanidza kumucheche musikana mucosa, uye mushure memasvondo mana vanokwanisa kubereka. Kureba kwehonye iyi kunogona kusvika mamita gumi! Asi njodzi huru iripo ndeyekuti kana zvipembenene zvikawanikwa kwenguva yakareba, chirwere chinopera simba chinowedzera mumunhu. Zvokudya zvakasanganiswa nehupombwe zvinodzivisa kuumbwa kwe vitamin B12, iyo inofanirwa kuumbwa kwehemoglobin erythrocytes. Zviratidzo zvinokuvadza zvechirwere zvachose kushaya simba, kupera kwekugadzikana, kukanganisa, kuwedzera kwemwoyo, kuora musoro kwepamusoro uye chizuru. Nokuda kwezviratidzo izvi, unofanira kubhadhara uye kubvunzurudza kune unyanzvi.

Kukosha kweva crustaceans kuvanhu: zvakanaka uye zvisina kunaka

Hazvibviri kutaura zvakananga pamusoro pezvinorehwa nevanokwidziridza muzvisikwa. Ichokwadi, chinhu chinonyanya kukosha ndechekuti ivo vose vanobatanidzwa zvakakosha mumaketani ezvokudya, vanogona kuisa zvinyorwa zviduku uye mabhakitiriya kubva mumvura. Zvinonyatsozivikanwa kuti chirwere chechibhakitiriro chebambo rekumera ne coral polyps chinovaunza pamwe chete kubatsirwa. Mhando dzakawanda dzinopedzwa nevanhu. Zvisinei, vamwe vavo vanobatanidzwa muhupenyu hwehutachiona uye kurwisa rotifers uye vamwe vavo vemukirasi.

Nokudaro, crustaceans mhuka, iyo munhu anoshandisa zvakanyanya muupenyu hwake, iyo inogutsikana basa ravo rinokosha mune zvakasikwa.
