  2. Communication • Social behavior: is the interaction among animals of the same species. • Communication: is a transfer of a signal or message from one animal to another that results in some type of response. • Why do animals communicate with each other? • It helps them to survive: • 1) To defend a territory 2) to find food • 3) to warn others of danger 4) to find mates • 5) to identify family members • 6) to frighten predators

  3. Ways to communicate • Communication is done by signaling information through sound, touch, chemicals, and sight. • 1. Sound: • Examples are: • Wolves howl. • Dolphins whistles and complex clicking noises. • Singing of birds.

  4. Ways to communicate • 2. Touch: • Example is Chimpanzees groom each other. They pick bits of skin from each other’s fur. • They use grooming to calm and comfort one another, so, they do friendship or support.

  5. Ways to communicate • 3. Chemicals: • Pheromone is a substance that is released by the body and causes another individual of the same species to react in a specific way. • Examples are: • 1. Ants: secrete alarm chemicals to warn others of danger. • They also secrete recognition chemicals. • 2. Pheromones to attract mates in elephants and some insects. • 3. To control which colony member can reproduce “like the queen of the ants”.

  6. Ways to communicate • 4. Sight: Animals use visual communications. • Examples are: • Waggle dance in bees to spread news about food. • Ruffling feathers or showing teeth to scare another. • Bowing in dogs to show that they wants to play.

  7. Living together: • Some animals like tigers live alone. • Some like lions rarely live alone. They live in groups called prides. • They sleep, hunt and raise their cubs together.

  8. Benefits of living together: • Safer than living alone. • Groups can work together to find food. • Downsides of living in groups: • Animals compete with each other for food and mates. • Living in groups attracts predators. • Living in groups help diseases spread.
