Umxholo
Inkqubo ye- echinoderms okanye echinodermata Zizilwanyana zaselwandle ezingenamqolo kodwa zinedermoskeleton. Olu hlobo lwesilwanyana saselwandle sinee-calcareous plates okanye i-spiny granules ethe saa emzimbeni wonke. Kungoko igama layo: echinoderm, elithetha "ulusu olugqunywe ngameva”.
Amacwecwe e-calcareous aqulathe i-calcium carbonate kwaye, ezinye zazo, ziyathetha ngokufanayo nakwicala le-starfish, ngelixa ezinye zenziwe nge-welding zenza uhlobo lweqokobhe njengakwimichamo yolwandle.
Inkqubo ye- echinoderms banokuhlala kuphela kwimekobume yaselwandle. Oku kuhamba ngokurhubuluza emazantsi endalo yolwandle kunye nohlobo lwazo lokuzala kwakhona, ngaphandle kwezinye iimeko ezinamandla okuzihlaziya, njengoko kunjalo nge-starfish.
- Inokukunceda: Izilwanyana zeArtropod.
Njengabo?
Ii-Echinoderms zikhona symmetry ye-radial, ngakumbi ngakumbi zi-pentaradially symmetric. Oko kukuthi, amalungu abo omzimba abekwe ajikeleze iziko.
Azinantloko okanye ingqondo. Nangona kunjalo, bayakwazi ukubona ukuba kwenzeka ntoni ngapha kwabo ngeeseli zomzimba eziqokelela ulwazi kwimeko-bume. Kananjalo abanantliziyo kuba inkqubo yokujikeleza kwegazi ivulekile.
