The family Cervidae—the true deer—are remarkable even-toed ungulates (Artiodactyla) distinguished by their antlers, which are shed and regrown annually by males, and in some species, by females as well. They play vital ecological roles as herbivores and prey, and their members are adapted to diverse habitats worldwide. Key genera include Cervus (red deer, elk), Odocoileus (white-tailed and mule deer), and Alces (moose).
- Antlers are unique to deer and differ from the permanent, branched horns of other ungulates.
- Cervidae species use complex grazing strategies, impacting plant community dynamics.
- They are widely distributed, with species on every continent except Australia and Antarctica.
Antlers are calcium phosphate structures regrown annually, characteristic of the family *Cervidae*.
Characteristic Features of Cervidae
- Antlers: Complex, branched, and made of bone; primarily in males, occasionally females.
- Hooves: Even-toed, symmetrical.
- Dentition: Adapted for browsing and grazing, with well-developed molars.
- Tail: Usually short.
- Scent glands: For communication and territory marking.
Regrowing antlers are a distinctive feature of *Cervidae*.
*Cervidae* have antlers, even-toed hooves, and scent glands.
Major Genera and Representative Species
| Genus | Common Name | Notable Species | Distribution | Distinctive Traits |
|---|---|---|---|---|

All are genera, but *Hydropotes* is the genus for water deer, a unique member of *Cervidae*.
Major *Cervidae* genera include *Cervus*, *Odocoileus*, and *Alces*.
Deer belong to the order *Artiodactyla*.
Ecological Roles and Adaptations
Cervidae are key herbivores influencing vegetation dynamics through selective browsing and grazing, often shaping forest regeneration. Their feeding maintains biodiversity but can also cause overbrowsing in absence of predators. Antlers are used in male competition during mating seasons, facilitating reproductive success.
- Influence plant community structure and succession.
- Prey base for large carnivores; important in food webs.
- Some species migrate seasonally to optimize resource use.
Deer are herbivores, prey, and influence vegetation dynamics.
Distribution and Habitat
Cervidae species are widespread, inhabiting regions across North America, Europe, Asia, and parts of South America. They occupy diverse habitats from arctic tundra to tropical forests, with some species adapted to mountainous terrains while others thrive in lowland woodlands.
- Found on all continents except Australia and Antarctica.
- Adapted to cold climates (moose) and tropical forests (brocket deer).
*Cervidae* are primarily distributed in the Northern Hemisphere and parts of South America.
Deer inhabit forests, grasslands, and mountains.
Conclusion
Cervidae, the true deer, are an ecologically and evolutionarily important family of even-toed ungulates characterized by their unique antlers, diverse genera, and wide distribution.
- Antlers are a key trait and differ from horns.
- Major genera include Cervus, Odocoileus, and Alces.
- They occupy diverse habitats and play major ecological roles as herbivores and prey.
