In this chapter, students learn that the interactions between young animals and their parents help the offspring survive by focusing on the behaviors of a mother bat and her pup and a humanlike dinosaur dad and his son. Most insects, fish, frogs, salamanders, lizards, turtles, and snakes hatch from eggs and face life completely alone. But all of the animals spend a lot of time and energy taking care of their young. They develop a relationship with their little ones, and the parents and young learn to respond to one another in a way that keeps the offspring safe and healthy. Students learn that animal parents, including humans, help their young grow and stay safe and that the behaviors of the young also help them survive.
