You do not need oxygen for glycolosis. However, the ATP yeild is WAY lower than for oxidative phosphorylation. Theres also the nasty buildup of lactic acid (a metabolic end product of glycolosis). Animals that dive...and use up their oxygen stores before the end of the dive and thus have to rely on glycolosis for ATP....will usually have a significant recovery time after the dive in order to breakdown lactic acid byproducts.

Also note that although humans turn pyruvic acid to lactic acid if there is no oxygen present, some organisms can turn it to ethanol or butiric acid.
