Izilwane zasolwandle ziwela ezigabeni ezimbili eziyinhloko: ama-vertebrate nezingenamgogodla. Ama-vertebrate anomgogodla; ama-invertebrate awanalo.
Izazi ze-Oceanologists zihlukanisa amakilasi amakhulu ezilwane zasolwandle ezaziwa njengezinhlobo:
- i-jellyfish nama-polyps;
- ama-arthropods;
- izimbaza;
- ama-annelids;
- chordate;
- echinoderms.
Zonke izilwane ezinomgogodla ziyizingxabano, kufaka phakathi: imikhomo, oshaka namahlengethwa, izilwane eziphila ezweni nasemanzini, izilwane ezinwabuzelayo nezinhlanzi. Yize izilwandle zihlala amakhaya ezigidi zokuxabana, awekho ama-vertebrate amaningi njengoba kukhona ama-invertebrate.
Kunamaqembu amakhulu ayi-17 ama-invertebrate ahlala olwandle, isibonelo: ama-crustaceans, ama-semi-chordates namanye.

Isiphetho
Izilwane zasolwandle ezingavamile ziyizilwane ezihuquzelayo. Ngenkathi izilwane ezinwabuzelayo eziningi zihlala emhlabathini noma zichitha isikhathi emanzini ahlanzekile, kunezinhlobo ezihlala olwandle. Ezidume kakhulu kulezi yizimfudu zasolwandle. Baphila iminyaka eminingi, bakhule babe bakhulu. Olwandle, izimfudu ezindala azinazitha; zitshuza ngokujulile ukuthola ukudla noma ukugwema ingozi. Izinyoka zasolwandle olunye uhlobo lwesirhubuluzi esihlala emanzini anosawoti.
Izilwane zasolwandle ziwumthombo obalulekile wokudla kubantu. Abantu bathola ukudla olwandle ngawodwana futhi nasemikhunjini emikhulu yasolwandle, ukudla kwasolwandle kumnandi, kunempilo futhi kushibhile kunenyama yezilwane ezinegazi elifudumele.
