Vertebrate and Invertebrate animals activity for 5th grade Primary ... - Free Printable

Let's solve the worksheet step by step.

1. Are the following animals vertebrate or invertebrate?

We need to identify whether each animal has a backbone (vertebrate) or not (invertebrate).

- Crab → 🐋 Invertebrate
*Reason: Crabs are crustaceans and belong to the phylum Arthropoda. They have an exoskeleton but no backbone.*

- Blue bird → 🐦 Vertebrate
*Reason: Birds have a backbone and belong to the class Aves.*

- Toad/Frog → 🐸 Vertebrate
*Reason: Frogs are amphibians and have a backbone.*

- Spider → 🕷️ Invertebrate
*Reason: Spiders are arachnids (also part of Arthropoda). They lack a backbone.*

- Jellyfish → 🍇 Invertebrate
*Reason: Jellyfish are cnidarians and do not have a backbone.*

- Snake → 🐍 Vertebrate
*Reason: Snakes are reptiles and have a backbone.*

✔ Answers for Question 1:
- Crab → Invertebrate
- Blue bird → Vertebrate
- Toad → Vertebrate
- Spider → Invertebrate
- Jellyfish → Invertebrate
- Snake → Vertebrate

2. Match the vertebrate animal and the kingdom it belongs to.

Note: The term "kingdom" is slightly misleading here — in biology, animals belong to the Kingdom Animalia, but these animals are grouped into classes within that kingdom. So we're matching animals to their class or group.

Let’s match each animal to its correct group:

- Lion → 🐅 Mammals
*Lions are mammals (warm-blooded, have fur, give birth to live young, nurse with milk).*

- Salmon → 🐟 Fish
*Salmon are fish (live in water, have gills, scales, fins).*

- Frog → 🐸 Amphibians
*Frogs are amphibians (live in water and on land, moist skin, lay eggs in water).*

- Lizard → 🦎 Reptiles
*Lizards are reptiles (cold-blooded, scaly skin, lay eggs).*

- Parrot → 🐦 Birds
*Parrots are birds (feathers, wings, lay eggs, warm-blooded).*

✔ Answers for Question 2:
- Lion → Mammals
- Salmon → Fish
- Frog → Amphibians
- Lizard → Reptiles
- Parrot → Birds
