Okuhlukahlukene ngesimo semvelo kanye nezinsiza. Isikhuphashi sasemadwaleni sasogwini oluseningizimu (i-Palinurus gilchristi) sihlala endaweni eyodwa okuyisengxenyeni eseningizimu neNingizimu Afrika, okuba sezindaweni eziphansi olwandle ezinamadwala asekujuleni okungamamitha angama-50 kuya kuma-200 futhi sigcina phakathi kwe-Cape Agulhas eningizimu-ntshonalanga kanye naseMonti enyakatho-mpumalanga. Lolu hlobo lwezinhlanzi lutholakala ezindaweni ezimbili ngobuningi obulungele ukuhweba: kude nogu lwase-Agulhas, endaweni elinganiselwa kumakhilomitha angama-200 ngasogwini, nasezindaweni eziseduze kogu (amakhilomitha ama-2 kuya kwangama-50 usuka ogwini) phakathi kwase-Mossel Bay naseMonti. Izindawo zokudoba okwakudotshwa kuzo emandulo zihlukaniswe zaba yizindawo ezine, i-Agulhas Bank, iMonti kanye ne-Port Alfred. Indawo yase-Port Alfred inendawo yokudoba eqondile, evulekayo eMonti nase-St Francis bese ivuleke kakhulu kakhulu e-Agulhas Bank. Isikhuphashi sasemadwaleni sasogwini oluseningizimu siwuhlobo lwenhlanzi yasemanzini abandayo esikhula kancane futhi esiphila isikhathi eside. Indawo eduze nogu ephakathi kwe-Danger Point ne-Cape Agulhas iyindawo ebalulekile okuhlala kuyo lolu hlobo lwezinhlanzi olusakhula, ezithuthela e-Agulhas Bank uma sezikhulile kanye nasendaweni eseduze nogu ephakathi kwe-Mossel Bay ne-Port Elizabeth. Izikhuphashi zasemadwaleni eziba phakathi kwe-Port Alfred neMonti zivame ukuba zincane, zikhule ngokungasheshi futhi azifuduki. I-Slipper lobster (i-Scyllarides elisabethae), Ingwane (i-Octopus magnificus), i-Panga, i-Hagfish ne-Kingklip zithathwa ngokuthi zingokudotshwa kungaqondiwe embonini ye-SCRL.
