Arthropods Characteristics
- Invertebrate metazoans
- Possess an exoskeleton that covers a segmented body
- Have jointed segmented appendages
- Specialize in certain appendages and body regions that support them
- Have an exuvia (skin covering) that is replaced by a shell or cuticle
- Can move using the flexible parts of the cuticle
- Grow by shedding their exuvia periodically in a process known as moulting or exuviation
Arthropods Classification
