Explanation:

• Snails are mollusks. Mollusks lack a backbone, so they are invertebrates.
• Worms (like earthworms) are annelids. Annelids do not have a vertebral column, so they are invertebrates.
• Crickets are insects. Insects are arthropods and lack a backbone, so they are invertebrates.
• Horses are mammals. Mammals have a backbone (vertebral column), so they are vertebrates.
• Frogs are amphibians. Amphibians have a backbone, so they are vertebrates.
