  Definition

  Animals have two types of vision, namely stereoscopic vision and monocular vision, in addition to having a different hearing frequency range for each animal.
• Stereoscopic vision

  Both eyes are in front of the head

  Both eyes are used to see an object

  A smaller field of vision

  Can estimate the position and distance of an object more accurately

  Examples: tigers, eagles, and bears
• Monocular vision

  One eye on each side of the head

  Only one eye is used to see an object

  Wider field of vision

  Inaccurate distance and position estimates

  Examples: deer, goats, and cows
• The stereophonic hearing:

  • Hearing uses both sides of the ear
  • Helps determine the direction and location of sound
• Dogs

  67 - 45,000

  Mice

  200 - 76,000

  Dolphin

  150 - 150,000

  Bat

  2,000 - 1,110,000
• Hearing frequency range (Hz)

  Dogs

  67 - 45,000

  Mice

  200 - 76,000

  Dolphin

  150 - 150,000

  Bat

  2,000 - 1,110,000
• Feathers

  • Hedgehog (Hystrix africaeaustralis)
  • Has sharp and strong feathers on the body and will release thorns towards the enemy as a defense system

  Electric field

  • Electric fish (Gymnarchus niloticus)
  • The electrical organs in fish produce an electric field that can detect the direction of a nearby object or organism
• Pheromone

  • Beetle (Melolontha melolontha)
  • Male beetles use antennae to detect pheromones produced by female beetles to find breeding mates

  Organ Jacobson

  • Snake (Vipera Crotalinae)
  • This organ is located in the palate of the snake's mouth which can detect the odor that has accumulated on the tongue and in turn detect enemies

  Lateral line

  • Fish
  • The lateral lines on the body of the fish can detect changes in water pressure, detect prey, and aid movement
