What is Phylum Arthropoda?

• Arthropoda is the group of animals that have specialised joint appendages, an adaptation seen in their legs.

For example, spiders, cockroaches, ants, beetles, etc.

Arthropods

• Arthropods are triploblastic and coelomate organisms, their body is developed from three germ layers: endoderm, mesoderm,and ectoderm.
• The body has a true body cavity. They have three major divisions of their body: head, thorax, and abdomen.
