Peta is of Greek origin and means "wide expanses of water" or "large sea". It's a unisex name, but it's more commonly used for females. The name Peta gained some popularity in the late 20th century, possibly due to its association with environmental activism, as PETA (People for the Ethical Treatment of Animals) is a well-known organization. However, it remains relatively rare as a given name.
"Peta was born six times in 1998."
