					      Behavioral Adaptations
Goals:
 1. To be able to define what a behavioral
 adaptation is and describe the different
 types of behavioral adaptations.
 2. To provide different variations of
 behavioral adaptations and explain how
 they enable an organism to survive in a
 specific environment.
        What is a behavioral
           adaptation?
• Activities that help an organism survive
  – The activities can be learned or instinctive
    Types of Behavioral Adaptations
               (Animals)
• Migration – Behavioral adaptation that involves
  animals moving from one region to another and
  then back again.
• Some reasons that animals might migrate
  are:
  – Better climate
  – Better food
  – Safe place to live
  – Safe place to raise offspring
  – Reproduction purposes
                   Hibernation
• Hibernation- is a deep sleep in which an
  animal's body temperature drops to about the
  temperature of the environment. Body activities,
  such as heartbeat and breathing are slowed
  causing the animal to need very little
  food. Animals that hibernate are:
  –   bats
  –   woodchucks
  –   snakes
  –   bears
  –   squirrels
Hibernation (cont.)
                 Society
• Society - this is a behavioral adaptation
  that involves a group of animals of the
  same species that live and work together
  in an organized way.
  Birds
  Zebras
  Wolves
  Gorillas
  Fish
                 Protection
• Protection – Some organisms develop
  certain behaviors to protect themselves
  from predators.
  Opossum – play dead to avoid predators
  Puffer Fish – a puffer fish will blow itself up to
   make it appear much larger to a predator
  Porcupine – a porcupine will raise its quills
   and lash out at the predator
         Courtship Behavior
• Some animals develop behavior
  adaptations to attract mates for
  reproduction.
  Peacocks – Display feathers to attract female
   peacocks
  Hippopotamus – Fight each other each year
   for the attention of a female mate
  Hummingbird – These bird display several
   different behaviors that include males
   dancing, diving, and singing for the females.
      Behavioral Adaptations
             (plants)
• Plant behaviors are generally referred to
  as tropisms (how plants respond to stimuli)
  Phototropism – an plants response to light
  Geotropism or Gravitropism – a plants
   response to gravity
  Hydrotropism – A plants response to water
What type of tropism to you see?
What is the stimuli causing the
     tree bend upward?
What external force is causing
the roots to grow downward?
             Class Activity
• In your journals, create a new entry for
  “Behavioral Adaptation Video Clips”
• Watch the different video clips and record
  the following for each clip: (answer in
  complete sentences)
  Identify the behavioral adaptation shown.
  Explain how the behavioral adaptation helps
   the organism survive in their environment.
