Metamorphosis- amphibians, fishes, insects

•Biological process of animal’s growth and physical development through sages characterized by the change in body structure

Amniotic eggs - reptiles, birds, mammals

•The eggs are not laid in the water and contain membrane that covers the embryo (amnion)

Ectothermic scales - fishes, amphibians, reptiles, and invertebrates

•Body temperature depends on environment

Spinal cord – vertebrates

•a hollow tube of nervous tissue part of CNS

Gills in adults – insects, mollusks, crustaceans, amphibians, fishes

•respiratory organ in aquatic animals

Lungs in adults – birds, reptiles, mammals, some fishes and some amphibians

•respiratory organ for the extraction of oxygen from the atmosphere

External fertilization – amphibians and fishes, some invertebrates such as coral and sea anemones

•fertilization outside of the female's body (usually in water).
