We had a chance to learn about the Animal Kingdom. Animal kingdom has 2 groups, vertebrates and Invertebrates.
Vertebrates are animals with back bone. Vertebrates are Mammals, Fish, Amphibians, Reptiles and Birds.
Invertebrates are animals without a backbone. Invertebrates are Protozoa, Echinoderms, Mollusks, Arthropods and Annelids.
We also learnt a word called 'Metamorphosis'. This is when an animals changes form. Butterflies and Frogs go through this change. Butterfly starts as caterpillar, then reach larva stage. They make a cocoon and become butterflies.
Frogs are eggs that become tadpoles which then grows legs to become a young frog. Tadpoles have gills to breathe. Finally the tail disappears becoming a frog. Frog breathes through its lungs or skin.
