Vamwe vavo translucent ganda, panopinda translucent zvomukati.

chikafu

Nemerteans - Nokuhonye, rine elongated muromo yokutanga tubular mhando. Inside rine chaiwo mouthparts proboscis, izvo rakakunguruswa vanyura muviri mhango uye iri zvomukati, kana mhuka ugere. Panguva pakuvhima, chubhu ichi mapurasitiki honye anotendeuka huchikandwa nenzira akuvara pasi pokudzora hydraulic kumanikidzwa. Mining yakafukidzwa namira, mukobvu uye with madzihwa.

Rinodya nemerteans? Honye anogona kumedza zvakatapwa kutadza kufamba rose kana kuiganhura vachiita migove. Vamwe mhuka aimiririra mhando envelop chakaurawa ari nhumbana pamusoro madzihwa, kusiya prozapas varo.

zvemukati mamiriro

Nemerteans - Nokuhonye, izvo haana muviri mhango pacharo. All pakakoromorwa pakati zvomukati azara connective zvinyama - parenchyma. Mukati akauya shure, pakati uye pamberi ura.

Nemertean vane zvikuru dzakabudirira kweropa hurongwa pakati Ribbon serin'i nehonye. Kana kufema hurongwa, musaita mhuka idzi. Okisijeni saturation masero kunoitika kuburikidza chionekeso rayo kuburikidza ganda.

Tsinga yakavakirwa panheyo ortogona. Nemamwe mashoko - masero etsinga dzinoumba dzakananga fibers, uye avo inounganidzwa vari tsinga hunde dzacho.

makirasi

Kusiyanisa zvinotevera zvidzidzo nemerteans:

1. Anopla - vanonzi unarmed nehonye. A pachena kuchiitwa mukirasi iyi rezvisikwa ndiko pasina proboscis iri nemumuromo mhango. Food unobatwa kuburikidza buri, riri munzvimbo abdominal mhango. mumiririri yakajeka mukirasi iyi anoita hofori nemerteans gungwa inonzi Lineus Longissimus, iyo muviri kunogona kusvika mamita 30 uye wakafara makubhiti kwete kupfuura imwe sendimita.
2. Nemerteans Nokuhonye, Enopla kirasi ane proboscis pamberi muviri. Last akandwe kunze, achirova munhu akawanda stilettos uye vachivhara madzihwa wake gobvu. Nhengo dzekirasi ichi vari kusiyaniswa kunyanya mwero saizi.

Mararamiro

Vazhinji makonye, ayo semhosva nemertean imhuka zvomumvura kuti vararame pasi. Zvisinei, tinoziva kwazvo yakawanda mhando Freshwater zvisikwa ichi mhando. Panewo nomumwe nevamiririri nemerteans nyika.

Nemerteans - gonye kuti dzinodya dzimwe dzinosiya mararamiro. Vamwe mhuka dzakadai vakaisawo regai kundovhima pachavo, uye vari scavengers. Also anozivikanwa nemerteans, zviri parasitic ari jasi mhango pakati zvomumvura mollusks. Pari, pane tsananguro yakatodzama sezvakarayirwa 1 200 mhando nehonye.
