No, they are not. Vertebrates have vertebra, which are the bones in the spinal column. Arthropods are a group of animals that have no backbone but what's called an exoskeleton. a 'skeleton' outside the body like a shell.No they are invertebrates under the group ArthropodaArthropods are invertebrates
Decapods (Lobsters, crabs etc.) are examples of invertebrates that have shells or chitinous bodies that protect their bodies.
Some lower invertebrates have what is called a ganglia, which is basically a poorly developed brain, but many lower invertebrates have no brain, and just connections of nerves throughout the body, which is called a nerve net.
Yes, arthropods do have internal body tissue. However, they do not have bones. Animals without bones are called invertebrates.

Some synapomorphies of invertebrates include the lack of a vertebral column, a wide range of body plans, and a diverse array of feeding strategies. Invertebrates also typically exhibit bilateral symmetry and possess a decentralized nervous system.

Invertebrates exhibit remarkable diversity due to a wide range of traits, including varying body plans, reproductive strategies, and ecological roles. They can be found in almost every habitat, from deep oceans to terrestrial environments, demonstrating adaptability to different conditions. Additionally, their unique physiological features, such as exoskeletons in arthropods or soft bodies in mollusks, contribute to their evolutionary success and ecological niches. This diversity allows invertebrates to fulfill essential roles in ecosystems, from pollination to decomposition.
Barnacles are invertebrates because their shells are outside of their body - they do not have an internal skeleton with a backbone.
