| 1.4 | 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:
-
Hearing uses both sides of the ear
-
Helps determine the direction and location of sound
|
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 |
