  • 3. 

    Is an Octopus' Brain to body ratio comparable to that of other intelligent animals?

    • True

    • False

    Correct Answer
    A. True
    Explanation
    The answer is true because an octopus has a highly developed and complex brain relative to its body size. Octopuses have the ability to solve puzzles, learn from experience, and exhibit problem-solving skills, which are indicative of intelligence. Their brain-to-body ratio is comparable to that of other intelligent animals such as dolphins and some primates. This suggests that octopuses possess a high level of cognitive abilities despite their different evolutionary path.

  • 4. 

    Can Octopuses learn from observation?

    • True

    • False

    Correct Answer
    A. True
    Explanation
    Octopuses have been observed to learn from observation. They possess highly developed cognitive abilities and are known to observe and imitate the behavior of other octopuses. They can learn new skills by watching and mimicking the actions of their peers. This ability to learn from observation is considered a form of social learning and is believed to contribute to their adaptability and survival in their natural environment.

  • 5. 

    Can an Octopus easily shift its shape according to need

    • True

    • False

    Correct Answer
    A. True
    Explanation
    Octopuses have a remarkable ability to change their shape and camouflage themselves according to their surroundings. They achieve this through a combination of muscle contractions and the ability to manipulate their skin pigments. By contracting and expanding their muscles, they can alter the shape of their body and even mimic the texture of objects in their environment. This incredible adaptability allows them to blend seamlessly into their surroundings and evade predators or ambush prey. Therefore, it can be concluded that an octopus can easily shift its shape according to its needs.

    Which all things do Octopuses possess?

    • Lungs

    • Spine

    • Brain

    • Plural Noun

    Correct Answer
    A. Brain
    Explanation
    Only brains!

    Rate this question:

  • 7. 

    Can an Octopus change its texture and colour according to its surroundings?

    • True

    • False

    Correct Answer
    A. True
    Explanation
    Octopuses have the remarkable ability to change their texture and color to blend in with their surroundings. This is achieved through specialized cells called chromatophores, which contain pigments that can expand or contract to create different patterns and colors. By adjusting the size and distribution of these pigments, octopuses can mimic the colors and textures of their environment, providing them with effective camouflage and allowing them to remain hidden from predators or prey. Therefore, it is true that an octopus can change its texture and color according to its surroundings.

  • 8. 

    How is the Octopuses' neuron network spread out?

    • Central brain 20% ; optic lobes 20% ; tentacles 60%

    • Central brain 30% ; optic lobes 10% ; tentacles 60%

    • Central brain 30% ; optic lobes 40% ; tentacles 30%

    • Central brain 10% ; optic lobes 30% ; tentacles 60%

    Correct Answer
    A. Central brain 10% ; optic lobes 30% ; tentacles 60%
    Explanation
    The octopus's neuron network is spread out with 10% in the central brain, 30% in the optic lobes, and 60% in the tentacles.

    What does Cephalopoda mean in Greek?

    • Octopuse

    • Head Feet

    • Large Brains

    • Mollusk

    Correct Answer
    A. Head Feet
    Explanation
    Cephalopoda is derived from the Greek words "cephalo" meaning head and "poda" meaning feet. Therefore, the term Cephalopoda refers to organisms that have feet or tentacles attached to their head.

    Rate this question:

  • 10. 

    The Octopuses are Mollusks belonging to the order 

    • Cephalpods

    • Non Vertebrates

    • Cephalopoda

    • Petromyzontomorphi

    Correct Answer
    A. Cephalopoda
    Explanation
    The correct answer is Cephalopoda. Octopuses are classified as mollusks belonging to the order Cephalopoda. Cephalopods are a group of marine animals that include octopuses, squids, and cuttlefish. They are characterized by their highly developed nervous system, complex behavior, and ability to change color and shape. Octopuses have a distinct head with large eyes, a soft body, and eight arms with suckers. They are considered to be highly intelligent and are known for their problem-solving abilities.

    How does an Octopus react to outside stimuli?

    • It acts based on a specific behavioral response stored in its brain for the situation in front of it

    • Its brain center activates appropriate muscles according to the task

    • It turns to its visual memory for help

    • Calls the individual body part which has to act

    Correct Answer
    A. It acts based on a specific behavioral response stored in its brain for the situation in front of it
    Explanation
    The correct answer is that an octopus acts based on a specific behavioral response stored in its brain for the situation in front of it. Octopuses have complex nervous systems and are capable of learning and remembering specific behaviors. They can adapt their reactions to different stimuli based on their previous experiences and stored knowledge in their brains. This allows them to respond appropriately to various situations they encounter in their environment.

    What are some uses of Octopuses' intelligence

    • Research for creating flexible robots

    • Petting them

    • Studying the evolution of intelligence

    • Help us understand about Intelligence and Consciousness

    Correct Answer(s)
    A. Research for creating flexible robots
    A. Studying the evolution of intelligence
    A. Help us understand about Intelligence and Consciousness
    Explanation
    Octopuses' intelligence can be used for research in creating flexible robots because their ability to manipulate objects and solve problems can inspire new designs and functionalities. Studying the evolution of intelligence in octopuses can provide insights into the development of intelligence in general and the potential for its evolution in different species. Additionally, understanding octopuses' intelligence can help us gain a deeper understanding of intelligence and consciousness as a whole, shedding light on the nature of these complex cognitive processes.

    Complete the following sentence with the right reason.The Octopus bends its arm to have food with the help of the muscle activation wave signals, which travel from the neural base to the tip of the arm and vice versa, following which ...

    • The involuntary actions set is activated and the Octopus bends its tentacles

    • These signals meet halfway, letting it know to bend at that particular spot

    • a follow up signal is send to the brain to bend

    • It consults its visual cortex for further action

    Correct Answer
    A. These signals meet halfway, letting it know to bend at that particular spot
    Explanation
    The Octopus bends its arm to have food with the help of the muscle activation wave signals, which travel from the neural base to the tip of the arm and vice versa. These signals meet halfway, letting it know to bend at that particular spot. This suggests that the octopus has a decentralized nervous system, allowing it to control its movements without needing input from the brain.
