❓ Frequently Asked Questions
What is an animal?
An animal is a multicellular, eukaryotic organism that is typically heterotrophic, lacks rigid cell walls, and can move at some life stage.
How are animals commonly categorized?
Animals are often grouped as invertebrates (no backbone) and vertebrates (with a backbone). Examples: insects and birds (invertebrates), fish and mammals (vertebrates).
What features define mammals?
Mammals are vertebrates with hair or fur, three middle ear bones, mammary glands, and usually give birth to live young; most are warm-blooded.
What is metamorphosis in animals?
Metamorphosis is a developmental process where an animal changes form between life stages. Complete metamorphosis: egg → larva → pupa → adult (e.g., butterfly). Incomplete metamorphosis: egg → nymph → adult (e.g., grasshopper).
