Nakuba zombili izingwadule ze-polar zifana, izitshalo ezikuzo zihlukile. Lolu gwadule oluseningizimu kubonakala sengathi alinakho ukuphila, iqembu nje lama-microorganisms atholakala ngeminyaka yawo-'70s. Lapha kunomoya omningi kakhulu kunomfowabo osenyakatho, komile futhi kwakhiwa amachibi e-hypersaline njengeLake Vanda noma ichibi laseDon Juan, elinosawoti omningi kangangokuthi ukuphila akunakwenzeka.
