Carnivora: An Overview
Introduction
Carnivora is an order of mammals that includes some of the most well-known and diverse predators in the animal kingdom. Members of Carnivora are primarily meat-eaters, though many have evolved to be omnivorous or even herbivorous. This order is characterized by specialized teeth and claws adapted for hunting and consuming flesh.
Key Characteristics
Dentition
- Carnivorans possess specialized teeth known as carnassials, which are modified molars and premolars designed for shearing flesh.
- Most members also have prominent canines used for grasping and killing prey.
Claws
- Many carnivorans have sharp, retractable or semi-retractable claws that aid in catching and holding prey.
Skeletal Structure
- Carnivorans typically have a robust skeletal structure that supports powerful muscles, enabling swift movement and forceful attacks.
Senses
- Enhanced senses of smell, sight, and hearing are common in Carnivora, aiding in hunting and detecting prey.
Classification
Carnivora is divided into two primary suborders: Feliformia and Caniformia.
Feliformia
- Feliformia includes cat-like carnivorans, which are generally more stealthy and agile hunters.
Caniformia
- Caniformia encompasses dog-like carnivorans, known for their endurance and often social hunting strategies.

Procyonidae (Raccoons and Relatives)
- Procyonidae consists of small to medium-sized, omnivorous mammals with dexterous front paws and masked faces.
- Members of this family are highly adaptable and can thrive in a variety of environments.
Notable Examples:

Hyaenidae (Hyenas)
- Hyaenidae includes animals that are more closely related to cats but bear a superficial resemblance to dogs.
- Hyenas are known for their strong jaws and social structures.
Notable Examples:
- Spotted Hyena (Crocuta crocuta): Lives in matriarchal clans and is both a skilled hunter and scavenger.
- Striped Hyena (Hyaena hyaena): A primarily scavenging species with a more solitary lifestyle.
- Brown Hyena (Parahyaena brunnea): Found in southern Africa, known for its shaggy coat and scavenging habits.
- Aardwolf (Proteles cristata): A specialized feeder on termites, with a diet that differs greatly from other hyenas.
Herpestidae (Mongooses)
- The Herpestidae family consists of small, agile carnivorans known for their boldness and social behavior.
- Mongooses are often found in groups and are famous for their ability to combat venomous snakes.
Notable Examples:
- Meerkat (Suricata suricatta): A social creature living in large colonies in the deserts of southern Africa.

Viverridae (Civets and Genets)
- Viverridae is a family of small to medium-sized carnivorans with elongated bodies, short legs, and often retractile claws.
