2. What is an Animal? Animal Characteristics –Eukaryotic –Multicellular –Heterotrophic –Lack cell walls Unique combination

3. Other Interesting Features Internal digestion (digestive tract) Life cycle –Diploid adults produce haploid gametes –Some develop directly to adult form –some go through a larval (immature) stage Metamorphosis = change in body from larva to adult
