The Importance of Responses to Stimuli in Other Animals |
| 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.
|
Differences between stereoscopic and monocular vision:
|
Stereoscopic vision
|
Monocular vision
|
|
Both eyes are in front of the head
|
One eye on each side of the head
|
|
Both eyes are used to see an object
|
Only one eye is used to see an object
|
|
A smaller field of vision
|
Wider field of vision
|
|
Can estimate the position and distance of an object more accurately
|
Inaccurate distance and position estimates
|
|
Examples: tigers, eagles, and bears
|
Examples: deer, goats, and cows
|
The stereophonic hearing:
|
Animals
|
Hearing frequency range (Hz)
|
|
Dogs
|
67 - 45,000
|
|
Mice
|
200 - 76,000
|
|
Dolphin
|
150 - 150,000
|
|
Bat
|
2,000 - 1,110,000
|
The diversity of sensory organs and animal responses:
|
Sensory organs
|
Response
|
|
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
