About Cervus elaphus Linnaeus, 1758
The red deer, scientifically named Cervus elaphus Linnaeus, 1758, is the fourth-largest living deer species; only moose, elk, and sambar deer are larger. It is a ruminant that digests food in two stages, and like camels, goats, and cattle, it has an even number of toes on each hoof. European red deer have noticeably longer tails than their Asian and North American relatives. There are subtle appearance differences between the various red deer subspecies, mostly in body size and antler traits. The smallest subspecies is the Corsican red deer, native to the islands of Corsica and Sardinia, while the largest is the Caspian red deer, also called maral, found in Asia Minor and the Caucasus Region west of the Caspian Sea. Red deer in central and western Europe vary widely in size, with some of the largest individuals living in the Carpathian Mountains of Central Europe. Historically, Western European red deer reached large sizes when they had access to ample food, including human-grown crops. Descendants of introduced red deer populations in New Zealand and Argentina have also grown quite large in both body and antler size. Large male red deer (stags), such as those of the Caspian red deer subspecies or stags from the Carpathian Mountains, can be close to the size of North American elk. Female red deer are much smaller than male red deer.
