There are four types of eukaryotes: animals, plants, fungi, and protists. Protists are a group of organisms defined as being eukaryotic but not animals, plants, or fungi; this group includes protozoa, slime molds, and some algae.

All animals are eukaryotic, multicellular organisms, and most animals have complex tissue structure with differentiated and specialized tissue. Animals are heterotrophs; they must consume living or dead organisms since they cannot synthesize their own food and can be carnivores, herbivores, omnivores, or parasites.

First, we don't even know how many types of animals there are in the world, let alone how many individual animals there are. Scientists have recently estimated that there are approximately 8.7 million species on Earth. They believe that 1-2 million of those species are animals.

Animals generally communicate using four methods: visual, auditory, tactile and chemical. Some species rely more on one form of communication over another; however, they all various methods to show affection, ward off threats or attract a mate.
