Spiders, shrimp, and snails are examples of

Explanation:
These animals share a backbone-free status. Spiders and shrimp are arthropods with exoskeletons, while snails are mollusks, yet none have a vertebral column. That absence of a backbone places them all invertebrates, a broader category that includes both arthropods and mollusks. If you needed more specificity, you’d note spiders and shrimp are arthropods and snails are mollusks, but the common trait connecting them here is that they lack backbones.
