Amphioxus nezimbaza: Izakhamuzi amanzi

Amphioxus iyona bakudala kakhulu izilwane ezifana chordal. Kodwa isikhundla sakhe isimiso sezwe organic ukunquma kwakungelula. Ososayensi baye kuthathwe imbaza yakhe wambiza lanceolate slug. eminyakeni engu-60 kuphela ngemva kokutholakala kwalesi isilwane seyaziwa ukuthi ezimela ehluke kakhulu. Kwaba njalo ngempela, ngokubukeka Amphioxus nezimbaza uhlanganise silula. Banezinhliziyo umzimba esithambile, okungasekelwe ihlukene.

ugesi

Kodwa noma yiziphi kuvamile ekudleni Amphioxus futhi bivalves? Lona ukudla uqobo. Njengoba singena emzimbeni by filtration, sifaka ezincane, cyanobacteria, ciliates, ezinamagobolondo, amaqanda kanti izibungu nezinye izilwane. Bonke yisisekelo zooplankton futhi phytoplankton. Mineral izinto zazo ziyoncibilika emanzini, nayo amuncwa eziphilayo. Le ndlela supply yekwentiwa. Ngezindlela eziningi ezikhonjwe ukuphila umzimba Amphioxus futhi bivalves.

filtrators

Lezi izimbobo ezimbili ingxenye ezingemuva umzimba, okuyinto ukuvula phakathi komgodi we nesiphuku. Through the ephansi elizenzekelayo lingena amanzi izinhlayiya okwesikhashana ukudla. Futhi ngokusebenzisa phezulu isinikeziwe ngefomu okumsulwa.

Ukuhlunga e Amphioxus ihlobene eduze umoya. Cilia elise emphinjeni kanye kungxenye phakathi izimbotshana gill, unikeze zamanje amanzi njalo. Iphinde kwenzeka kanye negesi lokushintshisana.

Ngakho, siye sacabangela ukuthi jikelele Amphioxus yokudla okunempilo ne-shellfish. Lezi zilwane zifana ngokuya isakhiwo jikelele we wokugaya ukudla uhlelo izitho. Wamzalela hlobo.
