How Long Are Zebras Pregnant?

Zebras are pregnant for 375 days on average, with meaningful variation by species — Plains Zebra (the most common and widespread species) average 360 days, Mountain Zebra average 365 days, and the larger-bodied Grevy's Zebra average 390 days. This pattern, where larger species gestate longer, is consistent across the equid family and most large mammals generally.

Foal Development & Litter Size

Zebras almost always have a single foal. Foals are highly precocial, standing and able to run with the herd within about an hour of birth — an essential survival trait given the intense predation pressure zebras face on the open African savanna from lions, hyenas, and other predators.
