The word "animal" originates from the Latin word animalis, which means a living organism. Being multicellular and eukaryotic is what distinguishes animals from other living things. Animals can be classified as carnivores, herbivores, omnivores, or parasites depending on what they eat. They can also be grouped into those with backbones, referred to as vertebrates, and those without backbones, known as invertebrates (arachnids and insects). Vertebrates may include mammals, amphibians, reptiles, and birds. There are various types of animals and how they can be categorized; however, this article will only concentrate on those that start with letter R.
