predators and worms
This organism would belong to Hexapoda.
Soft bodied invertebrates classified into three groups based on body structure are flatworms, roundworms, and segmented worms. Flatworms have a flattened body, roundworms are cylindrical with a tapered ends, and segmented worms have distinct body segments.
Exoskeleton
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.

ok 1 is back spin, front and sides.
No, arachnids are invertebrates and they have four pairs of jointed legs.
Barnacles are invertebrates because their shells are outside of their body - they do not have an internal skeleton with a backbone.
Three major trends of evolution in invertebrates include the development of multicellularity, leading to more complex body structures and functions; the evolution of symmetry, particularly bilateral symmetry, which allows for more efficient movement and organization of body systems; and the emergence of specialized body systems, such as circulatory and nervous systems, which enhance survival and adaptability in various environments. These trends have contributed to the incredible diversity and ecological success of invertebrate species.
Mollusks are all invertebrates because they have no internal skeleton with a backbone. Their shells are outside of their body.
