Most animals are multicellular eukaryotes that move, digest food, and reproduce sexually or asexually. They are classified as herbivores, carnivores, or omnivores based on whether they eat plants, animals, or both. Animals have adaptations like fur, horns, camouflage, or behaviors that help them survive and reproduce in their environments. They can also be classified as vertebrates or invertebrates based on whether they do or do not have a backbone.

1. ANIMALS
(Just the Basics!)

2. • CHARACTERISTICS OF MOST ANIMALS:
– Multicellular
– Animal cells are eukaryotic (have nucleus, etc)
– Depend on other living things for food
– Digest food
– Move from place to place (locomotion)
– Most reproduce sexually, though some may also
reproduce asexually

3. • Herbivores are animals that eat only plants or
plant parts for energy

7. • Carnivores eat only other animals. Most
carnivores hunt, but some are scavengers.
• scavengers are carnivorous animals that eat the
remains of other animals

10. • Omnivores eat both plant matter and animal
flesh

14. • An adaptation is a variation that makes an organism
better suited to its environment
• Animals employ different adaptations to help them
survive and reproduce

15. • Adaptations for survival include fur, coverings,
horns, talons, mimicry, camouflage and
behavioral adaptations.
• Mimicry is when one animal closely resembles
another

16. - Some outer coverings that protect an animal
include quills and protective plates

19. • Camouflage is an adaptation that helps an animal
blend in to its environment

20. • Some animals display defensive behavioral
adaptations, such as a skunk’s spray

22. • CLASSIFICATION OF ANIMALS:
• Vertebrates are animals that have a backbone
– Humans, fish, snakes, birds…

23. • Invertebrates do not have a backbone
– Sponges, worms, insects…

26. • Symmetry refers to how parts of an animal are
arranged
• An animal with no definite shape is
asymmetrical – ex: sponge

27. • Animals that have body parts arranged in a circle
around a central point have radial symmetry
- Ex: jellyfish, hydra

28. • Many animals, including humans, have bilateral
symmetry. This means that they can be divided
into right and left sides, and the sides are mirror
images of each other.
