1.4 The Importance of Responses to Stimuli in Other Animals Flashcards
What are the two types of vision in animals?
Stereoscopic vision and monocular vision.
Where are the eyes positioned in animals with stereoscopic vision?
Both eyes are in front of the head.
How do animals with stereoscopic vision see objects?
Both eyes are used to see an object.
What is the field of vision like in stereoscopic vision?
It has a smaller field of vision.
How does stereoscopic vision help animals?
It allows accurate estimation of an object’s position and distance.
Name three animals with stereoscopic vision.
Tigers, eagles, and bears.
- Most predators / carnivores
Where are the eyes positioned in animals with monocular vision?
One eye is on each side of the head.
How do animals with monocular vision see objects?
Only one eye is used to see an object.
What is the field of vision like in monocular vision?
It has a wider field of vision and primarily sees in 2D because it lacks depth perception.
What is a disadvantage of monocular vision?
It makes distance and position estimates inaccurate.
Name three animals with monocular vision.
Deer, goats, and cows.
- Most herbivores / prey animals.
Why do animals with monocular vision have weak depth perception?
They do not receive overlapping images from both eyes, making it harder to judge distance accurately.
How do monocular vision animals judge depth?
They use motion parallax (closer objects move faster) and size comparison (comparing known objects).
What is stereophonic hearing?
Hearing that uses both sides of the ear.
How does stereophonic hearing help animals?
It helps determine the direction and location of sound.
What is the hearing frequency range of dogs?
67 - 45,000 Hz.
What is the hearing frequency range of mice?
200 - 80,000 Hz.
What is the hearing frequency range of dolphins?
40 - 100,000 Hz.
What is the hearing frequency range of bats?
2,000 - 110,000 Hz.
What defense mechanism does a hedgehog use?
A hedgehog has sharp, strong feathers and can release thorns to defend itself.
What sensory ability does the electric fish have?
It produces an electric field to detect the direction of nearby objects or organisms.
How do male beetles find mates?
They use their antennae to detect pheromones produced by female beetles.
What is the Jacobson’s organ in snakes used for?
It detects odors that accumulate on the tongue, helping snakes sense enemies.
What is the function of the lateral line in fish?
It detects changes in water pressure, helps locate prey, and aids movement.
