Below is the second part of "Baby Dolphin."
Mother Dolphin stays beside her baby throughout the summer. The "aunties" also take care of Baby Dolphin.
Baby Dolphin is very playful and curious. She can swim well and loves to nudge her mother.
Baby Dolphin is growing fast. Soon she will grow a thick layer of blubber like her mother. It will help her float and keep her warm.
Baby Dolphin is getting tired after playing so much. At night, she sleeps just below the surface of the water like the other dolphins.
Baby Dolphin is quick to learn each dolphin's unique whistle. The dolphins in the herd also bark, click, moan, and mew to keep in touch with one another and express their feelings.
Dolphins have no vocal chords, but they can produce sounds with a special oil-filled organ in their foreheads called the melon. These sounds come out of their blowholes.
The dolphins work together to take care of Baby Dolphin and the other young dolphins. They cooperate in feeding and defending the herd.
The dolphins are all spread out when a shark swims close to their group. Grown-up dolphins quickly surround Baby Dolphin and all the other young ones to protect them.
Dolphins always travel in small schools, or groups, to protect themselves against predators.
Suddenly four other grown dolphins rush toward the menacing shark. The adult dolphins ram it hard with their beaks, lifting it clear out of the water.
The shark flees, but some of the dolphins are exhausted and hurt. They help lift each other to the surface so they can rest and breathe through their blowholes.
The danger is gone, but Baby Dolphin stays close to the older dolphins. Baby Dolphin floats up with Mother Dolphin to take a breath of fresh air and rest for a short time.
If dolphins can protect themselves against their enemies like the shark, they can live a long time. Some dolphins live up to 35 years in the wild.
After the dolphins have rested, they celebrate by playing games in the warm water. Baby Dolphin flips through the air and uses her tail to splash her friends.
