Spiders, shrimp, and snails are examples of which major group?

Explanation:
Whether an animal has a backbone is the main idea here. These three animals do not have backbones, so they’re invertebrates. Vertebrates have backbones, which these do not. Mollusks is a more specific group that would include snails but not spiders or shrimp, so it doesn’t fit all three. So the classification that covers all of them is invertebrates.
