Students are investigating the life cycle of the spotted salamander. They learn that these salamanders must live close to water and lay eggs in water. After 20-60 days, the salamander eggs hatch as larvae. They must stay in the water until they mature into adult salamanders.

A butterfly has a larva stage, but a bird does not. A butterfly has a pupa stage, but a bird does not. A butterfly goes through complete metamorphosis, but a bird does not.
Compare and contrast the life cycle of a frog and the life cycle of a bird.
The life cycle of a frog has four stages, while the life cycle of a bird has three stages. Both animals hatch from eggs. Both animals grow, reproduce, and die. The life cycle of a frog includes tadpoles and a froglet, and the life cycle of a bird does not.
