'''Mabata mkia-ngumu''' ni [[ndege (biolojia)|ndege]] wa maji wa [[nusufamilia]] [[Oxyurinae]] katika [[familia (biolojia)|familia]] [[Anatidae]]. Manyoya ya mkia wao ni makavu na yametandawaa mara nyingi. Rangi ya dume ni kahawia au kahawiachekundu na domo lake lililovimba msingini ni buluu; jike ni mweusi au kijivu wenye domo la rangi ile ile. [[Spishi]] hizi huzamia kabisa ili kutafuta chakula. Hula [[mmea|mimea]] na [[invertebrata]] ya maji. Miguu yao iko nyuma sana, kama ile ya [[bata mzamaji|mabata wazamaji]], ili kujisogeza mbele vizuri ndani ya maji. Kwa sababu hiyo hawawezi kutembea vizuri. Hujenga tago lao ndani ya uoto mzito wa maji. Jike huyataga [[yai|mayai]] 3-8, lakini pengine hadi mayai 12 yanapatikana kwa sababu jike mwingine ameongezea mayai yake.
