To understand the diversity of life on Earth, it’s essential to look at the classification of animals in terms of their phyla and symmetry. Here’s a breakdown of the specified animals:
- 1. Snail
Phylum: Mollusca
Symmetry: Bilateral - 2. Fish
Phylum: Chordata
Symmetry: Bilateral - 3. Earthworm
Phylum: Annelida
Symmetry: Bilateral - 4. Anemone
Phylum: Cnidaria
Symmetry: Radial - 5. Frog
Phylum: Chordata
Symmetry: Bilateral - 6. Jellyfish
Phylum: Cnidaria
Symmetry: Radial - 7. Starfish
Phylum: Echinodermata
Symmetry: Pentaradial - 8. Alligator
Phylum: Chordata
Symmetry: Bilateral - 9. Crayfish
Phylum: Arthropoda
Symmetry: Bilateral - 10. Ant
Phylum: Arthropoda
Symmetry: Bilateral - 11. Elephant
Phylum: Chordata
Symmetry: Bilateral - 12. Coral
Phylum: Cnidaria
Symmetry: Radial
Each phylum represents a major group of animals, and understanding their symmetry helps in comprehending their body plans and evolutionary relationships. Bilateral symmetry is common among most animals, allowing for streamlined movement, whereas radial symmetry is often found in sessile organisms, enhancing their interaction with the environment. Pentaradial symmetry, seen in starfish, reflects a unique evolutionary adaptation among echinoderms.
