" NOJ QAB ZIB ZAUB MARKZAUB NCAWS, Txawm tias muaj ntau yam li ntawm cov ntses txiv ntoo, yog kev sib luag. Cov tsiaj no xav kom lawv ib puag ncig kom muaj cov yam ntxwv tshwj xeeb txhawm rau kom muaj sia nyob, tshwj xeeb tshaj yog siv rau salinity. Tias yog vim li cas hauv tsab xov xwm no peb yuav tham txog cov ntses dej, peb yuav paub
lawv txawv li cas los ntawm cov ntses hiav txwv thiab peb yuav pom ntau tus piv txwv.
Difference of dej ntses thiab seafish
Hais txog qhov sib txawv ntawm cov ntses dej thiab ntses hiav txwv peb yuav tsum xub txhais lub sij hawm homeostasis, txij no mus yog qhov sib txawv decisive. Homeostasis yog cov txheej txheem uas cov kab mob muaj sia ua kom nws cov txheej txheem tseem ceeb ruaj khov txawm tias muaj kev hloov pauv uas tshwm sim hauv ib puag ncig.
The river fish have greater facility in this aspect, since their external environment is more similar to the internal one, since the salinity of dej tsis siab. Yog li, dej dhau los ntawm nws cov gills thiab tawm los ntawm operculum yam tsis muaj kev tiv thaiv ntau. Tsis tas li ntawd xwb, lawv muaj lub raum tsim heev lim dej kom zoo.
Ntawm qhov tod tes, cov seafish muaj ib qho nyuaj ntxiv, thiab qhov ntawd yog qhov lawv ib puag ncig yog saline ntau dhau. Tom qab ntawd, los ntawm kev ua pa los ntawm lawv cov gills, ntau cov dej hauv lub cev raug tshem tawm. Vim li no, cov ntses hiav txwv haus dej ntau, nws lub raum txheej txheem rau expel ntau ntsevthiab tswj homeostasis.
Dangerous River Fish

+90 tus ntses dej hauv Spain
1. IN Spain,Hauv Spain, Teb tau yog ib txoj kev uas tau txais cov khoom noj rau ntau pua xyoo. Nws cov dej ntws, pas dej, cov av ntub dej thiab cov pas dej ua ke yeej ib txwm muaj ntau yam ntses noj. Txawm li cas los xij, nyob rau xyoo tsis ntev los no
kab kab txawv tau qhia tias ua rau peb cov ntses fauna puas lawm.
