Vertebrates and Invertebrates Worksheets - Free Printable

Explanation:
We need to label each animal as either a vertebrate (has a backbone) or an invertebrate (no backbone). Let’s go through each animal one by one:

1. Deer – Mammal → has a backbone → Vertebrate
2. Cactus – Wait! This is not an animal—it’s a plant. But the task says “Label each animal”, so maybe it's a mistake. However, since it's included in the worksheet and the title is “Vertebrates and Invertebrates” (which applies only to animals), we should assume this is likely meant to be a *lizard* or *gecko* on a cactus? But visually, it looks like a small lizard sitting on a cactus. In many such worksheets, that image represents a lizard, which is a reptile → has a backbone → Vertebrate. We’ll treat it as a lizard.

3. Fly – Insect → no backbone → Invertebrate
4. Turtle – Reptile → has a backbone → Vertebrate
5. Centipede – Arthropod (many legs) → no backbone → Invertebrate
6. Frog – Amphibian → has a backbone → Vertebrate
7. Bat – Mammal → has a backbone → Vertebrate
8. Crab – Crustacean (arthropod) → no backbone → Invertebrate
9. Octopus – Mollusk → no backbone → Invertebrate
10. Dolphin – Mammal → has a backbone → Vertebrate

Let’s double-check:
- Vertebrates: deer, lizard (on cactus), turtle, frog, bat, dolphin → 6 animals
- Invertebrates: fly, centipede, crab, octopus → 4 animals

Yes, that matches typical biology classification.
