Zvinoumba arachnids: Meso vangani chinyavada

Kusiyana dzakabudirira mhando arthropods, arachnids simba pake. meso avo vane nyore yakarongeka. On muviri kunogona kusvika mbiri nhanhatu, asi zviri nani anosimbisa Kusakwana maonero enyika yakapoteredza nyika. Mhinduro yomubvunzo pamusoro mangani maziso chinyavada havagoni kupa kunyatsonzwisisa madzidziro yayo kuona hurongwa. Saka zvine musoro kuti kunzwisisa sei yava akaderedzwa kurarama ne "optics" kukwana vakadaro.

Zvinoumba arachnids

Mapoka akasiyana mhando mukirasi iyi vari wakanyatsokodzera chinangwa. Nokuti vazhinji, chikuru basa iri kuridzwa kwete ziso, uye tactile nezvekufadza. On pemvura muviri vaine nzvimbo dzakakwirira nehanya. Kunyanya yakawanda tactile bvudzi makumbo zvine, kukonzera sangano, uye pedipalps (nogoschupaltsa).

madandaude zhinji vanobatanidza samambure ndibate. Maererano kupfuura nokufamba ari mutsvuku vanodzidza nezvezvinhu chero kugadzirwa. Visual maonero apo zvisinganyanyi kukosha. Forms, runochengeta uye kunovhima pasina padandemutande, vane dzakabudirira zvaakaratidzwa. Nokuti sangano iri kujairwa nomunzvimbo dzine, vanofanira kukwanisa kusiyanisa akapoteredza chokwadi.

Zvisinei, kuona maitiro avo hazvigoni kuenzaniswa "optics" okukura kuvakuru nezvipembenene. Eyes chinyavada (yaifananidzira pazasi) Uyewo hapana zano kunzwisisa kana ruvara zvimwe. Zvinofungidzirwa kuti nhengo suborder ichi ona kunyange kupfuura madandaude uye vanokwanisa kusiyanisa pachavo mhando kwavo chete kubva rikayerera kwechinhambwe masendimita mashomanana.

Simple uye kunzwisisa chiratidzo arthropods

Vision ari zvipembenene chinonyanya dzakabudirira. Panyaya iyi, maziso kazhinji vanodiwa dandemutande nyore. We dzakabudirira vamiririri tumbuyu - nyuchi, dragonflies, nhunzi nezvimwewo zvakafanana - Meso mukomboni vane faceted yakarongeka. Structural chinooneka chikwata muri ommatidia. Izvi, chokwadi, ndizvo kunzwisisa Manyiminya hurongwa. Pedyo, vanoumba kutarisana siyana. Ommatidium rinoumbwa imwe biconvex izvo (cornea), iro riri pasi läpinäkyvä cône kubudikidza ehupfumi akafanana izvo.

Pasi marongera masero (the retina), anokwanisa kugamuchira chiedza nemwaranzi. Vari zvakabatana tsinga harinzwi kuti kwokupa anonongedzera kuuropi. Kubva ommatidium ruzivo mumwe auya voga. Somugumisiro, mufananidzo rine yakatarwa pfungwa uye chakafanana nomufananidzo waMosesi.

In nhunzi nhamba vakadaro STRUCTURAL zvinhu ndiyo 4 th. In ziso rimwe. In zvakawanda mune kuremekedza ichi, dragonflies uye kunyange zvakawanda - kusvika 28 zviuru. Zvinozivikanwa maviri kuti dandemutande vashoma nameso. Vangani Meso chinyavada vane kunzwisisa marongerwo? Vane kunzwisisa mashandiro anoita ziso. Iye chinomiririrwa akawanda oga akaisa maziso, ommatidia. Uye mumwe peya makuru saizi uye anonzi rakakura. The zororo (5 nomwe) vanosarudzirwa laterally uye vanoonekwa chikamu.

Nyore lateral Meso (Stemm) vari zvipembenene mazana. Kutamira kune imwe yepamusoro padanho kukura, kutarisana hurongwa hwavo rakaoma. Rumwe rudzi nyore ziso (dorsal) haasi "aberekwazve" uye inoramba panguva iyoyo vaenzane uye nedzevakuru. Ommatidial mavari haina kuumbwa (hapana cône uye izvo). By achiona masero akaronga cornea chiedza. Kunyange repasi ruvara rukoko zvakabatana etsinga harinzwi.

Pezvinyavada: mararamiro

arthropods izvi kunowanzoitwa kuwanikwa munyika dzinopisa munharaunda. Dzimwe dziri diurnal, asi ruzhinji vavo vachiri vavhimi usiku. Vanongofunga kuvanda kubva Kupisa uvande munguva pasi matombo, driftwood uye dzimwe yakavandika nzvimbo.

Izvi pamwe akatsanangura dzavo kukwana chiratidzo. Cherechedza njodzi vanogona chete zvemandorokwati, uye nani akachinja kundovhima usiku. Asi hazvisi chete nokuda chaizvo zvechiratidzo kuona. Hazvinei zvikuru sei ziso chinyavada (yaifananidzira pazasi) - havasi kuita mutsindo basa kubatwa nyama. Zvinofungidzirwa kuti huru kukosha chaiwo kurwisa - vasanonoka sensors pamakumbo avo.

Circular kuisa chinyavada makumbo inopa mukana kunzwa kupfuura nokufamba muvhu kumativi ose. Kumhanya Mashoko anonongedzera dzakadaro (yakaderera makumbo avo vanonzwa pamberi) payo anosarudza chairo nzvimbo rechipfuwo. Meso iri kuridza yechipiri basa. Zvinonzi akacherechedza kuti kana iwe zviparadzanise chinyavada uye akuvara ari muchimiro chipingamupinyi mutete crevice, haagoni kurwisa kunyange zvemandorokwati. Anonongedzera kubva muvhu nokuda dzokubudisa kutama ayo vasanonoka Tabs iyi nyaya regai kusvika.

Meso vangani chinyavada

Habitat uye maitiro upenyu yekudyidzana kwakachinja chimiro zvisikwa izvi. Kwete chete ndivo mukuru kukura mumuviri uye zvimwe zvikamu zvaro, asi uwandu maziso. Pasinei yose, vane nyore yakarongeka.

How Meso vakawanda chinyavada, uye uko vari iri muviri? Vamwe dzemarudzi dzakashandisa kurarama chete peya. The kunonyanyisa nhamba - 12 ziso rakanaka. Uye mumwe vaviri (pachena hombe) iri pakati uye kukonzera. Vamwe dziri mumativi uye pasi mukomberedzo.

Takwira wacho pamberi nenzara, kuti chinyavada anomutsa payo musoro wake uye muromo kuboorwa dzinopfonda kuti panopera muswe. kuzvidzora izvi vangani Meso chinyavada here? Anofungidzirwa, riri pamusoro peya kune pamwero wakarurama uye mutoro. Ko nyore mamwe kuomesa maziso kuona hurongwa (yakatanga kuvandudza) kana isina (haisati atrophy), Hazvikwanisiki kuti asimbise.
