Examples of Terrestrial Animals

1. Examples of Terrestrial Animals

Learn about the various types of terrestrial animals, or a group of animals categorized by their need to live exclusively or almost exclusively on land. Find out what makes an animal 'terrestrial.'

Bird Circulatory System: Function & Structure

2. Bird Circulatory System: Function & Structure

In this lesson, we'll go over the important structures of the bird circulatory system and explain how they are different from those of other animals. We'll also learn the function for the structures of the circulatory system.

Do Earthworms Have a Closed or Open Circulatory System?

3. Do Earthworms Have a Closed or Open Circulatory System?

In this lesson, you will learn to differentiate between a closed and an open circulatory system. Read on, and you will be able to characterize the earthworm's circulatory system!

Acrosome: Reaction, Function & Definition

4. Acrosome: Reaction, Function & Definition

When a sperm finds an egg, the complex process of fertilization has only just begun. In this lesson, you'll learn about the acrosome, a specialized vesicle in the head of the sperm, and the important roles it plays in fertilization.

Morula: Definition & Concept

5. Morula: Definition & Concept

Shortly after fertilization takes place, a lot of cellular activities begin to occur. In this lesson we will investigate the formation of a morula as well as what happens to the morula.

Zona Pellucida: Definition & Concept

6. Zona Pellucida: Definition & Concept

The zona pellucida (ZP) is an important, integral structure for the egg both before and after fertilization. Learn how the ZP works to make reproduction possible and protects the new life it surrounds.

Cnidaria Digestive System

7. Cnidaria Digestive System

Explore the digestive system of the phylum Cnidaria. Learn about the structure and function of their digestive system and its parts, as well as what foods they are digesting.

Reptile Circulatory System

8. Reptile Circulatory System

In this lesson, we'll delve into the reptile circulatory system. The lesson will cover the structure and function of reptile blood vessels and heart structure, as well as special adaptations of these systems.

Blastocoel: Definition & Concept

9. Blastocoel: Definition & Concept

Formation of the blastocoel is an important step in development -- it sets the stage for future growth and change in the cells of the early embryo. Learn how the blastocoel helps and protects these cells.

Gastrula: Definition & Concept

10. Gastrula: Definition & Concept

A gastrula is a developmental stage of some animal embryos in which different germ layers are present. In this lesson, learn about the structure of a gastrula, how it forms, and what its germ layers become in adult humans.

Germ Cells in Humans: Definition & Concept

11. Germ Cells in Humans: Definition & Concept

Although you may think germ cells have something to do with getting sick, this is 100% not true. This lesson defines germ cells and provides an overview of their processes.

Habituation in Animals: Definition & Example

12. Habituation in Animals: Definition & Example

Habituation is a simple form of learning that all animals, including people, are capable of. In this lesson, you will learn what it is, how it occurs, and why it's a big energy saver.

Mimicry in Animals: Definition & Examples

13. Mimicry in Animals: Definition & Examples

Living things have evolved some very unique and fascinating ways to trick predators and competitors. Mimicry is one such tactic. Learn about mimicry and explore some of the more wild and interesting examples of it.

Allantois: Function & Definition

14. Allantois: Function & Definition

The allantois can be found within the structure of an embryo, and in that way aids in the development of many organisms, including humans. In this lesson, learn about its function and definition.

Endoderm Layer: Definition & Derivatives

15. Endoderm Layer: Definition & Derivatives

Do you know what the lungs and intestines have in common? They both actually develop from the same tissue layer in an embryo. Learn what other structures are also derived from this same embryonic layer in this lesson.

Polar Body: Definition, Formation & Twinning

16. Polar Body: Definition, Formation & Twinning

This lesson describes polar bodies. It answers two questions: what are they, and how do they form? It then describes how twins might arise because of polar body formation.

Cnidaria Respiratory System

17. Cnidaria Respiratory System

In this lesson, you will learn about the animals of the phylum Cnidaria, what a respiratory system is, and how the respiratory system of a cnidarian works. Be sure to complete the quiz after the lesson.
