About This Chapter
How It Works:
- Identify the lessons in the ScienceFusion Introduction to Animals chapter with which you need help.
- Find the corresponding video lessons with this companion course chapter.
- Watch fun videos that cover the introductory animals topics you need to learn or review.
- Complete the quizzes to test your understanding.
- If you need additional help, rewatch the videos until you've mastered the material or submit a question for one of our instructors.
You'll learn all of the science topics covered in the textbook chapter, including:
- Evolutionary history of animals and characteristics of vertebrates and invertebrates
- Identifying a producer and define its ecological role
- Radial symmetry, asymmetry and bilateral symmetry
- Types of skeletal systems
- Types and characteristics of chordate animals
- Characteristics of flat, round and segmented worms
- Radiata, protostomes and deuterostomes

1. The Evolution of Animals: Importance & Evolutionary History
The animal kingdom ranges from simple organisms like sponges to complex organisms like humans. We will look at some defining characteristics of animals as well as examples of both invertebrates and vertebrates.
2. Ecology Producer: Definition & Explanation
This lesson will define what a producer is and what its role is in an ecosystem. It will also discuss the different kinds of producers and give some specific examples of them.
3. Types of Symmetry in Animals
Scientists use symmetry to identify and group animals into categories. This lesson describes the types of symmetry found in animals. You will learn about what each type of symmetry looks like, as well as how to identify them in different animals.
4. Invertebrates: Definition & Examples
From bees to lobsters and octopi to cockroaches, invertebrates are everywhere. This lesson introduces them as a major group within biology and discusses their relationship with the human race.
5. Hydrostatic Skeletons, Exoskeletons & Endoskeletons
You have a skeleton, right? Do you know what kind of skeleton? Do you know the other types of skeletons and what animals have them? This lesson will help answer these questions for you!
6. Vertebrates: Definition, Features & Classification
Vertebrates are an interesting collection of animals, including humans, that have evolved over millions of years. Birds, reptiles, amphibians, mammals and even fish are included in the vertebrate category. Find out more here!
7. Chordates: Features, Groups & Characteristics
Chordata is a group of related vertebrates and invertebrates. How can vertebrates and invertebrates be related? They appear to be very different. Read on to find out.
8. Worms: Types & Features
You may not know this, but worms are everywhere. Many are so tiny that we can't see them crawling all over the place like we can earthworms. In this lesson, we'll learn about some of the different types of worms around us.
9. Radiata: Definition and Characteristics
The super-phylum Radiata describes a unique and interesting group of animals. In this video lesson you'll identify various animals that belong in this classification as well as describe the characteristics that make them so identifiable.
10. Protostomes: Definition and Characteristics
Though you may not be able to tell just by looking at them, protostomes are an evolutionarily related group based on shared characteristics of their body plans. In this lesson, you will identify these characteristics, as well as see examples of the variety of animals this group encompasses.
11. Deuterostomes: Definition and Characteristics
Deuterostomes, like tunicates and urchins, are amazing creatures that are classified together because they share aspects of their evolutionary pasts. In this lesson, you'll identify these characteristics and see what makes this group of animals unique.
