Characteristics of Arthropods

• Segmented bodies
• Exoskeleton made of chitin
• Jointed appendages
• Bilateral symmetry
• Open circulatory system
• Well-developed nervous system

Classification of Arthropods

Arthropods are classified into four main subphyla:

1. Trilobitomorpha
2. Chelicerata
3. Mandibulata
4. Crustacea

Importance of Arthropods

Arthropods play crucial roles in ecosystems, including pollination, decomposition, and serving as a food source for other animals. They also have economic importance as pests and as a source of food and materials for humans.

Common Arthropods

Some common examples of arthropods include:

• Insects: such as ants, bees, butterflies, and beetles
• Arachnids: such as spiders, scorpions, and ticks
• Crustaceans: such as crabs, lobsters, and shrimp
• Myriapods: such as centipedes and millipedes

Study Tips

• Use diagrams to understand the anatomy of arthropods.
• Observe arthropods in their natural habitats or in a controlled environment, such as a terrarium or aquarium.
• Research the ecological and economic roles of arthropods.
• Review the classification and diversity of arthropods to understand their evolutionary history.
