Animals have eyes shaped in different ways, and have various speciali...
Statement 1: Eyes of a crab are quite small but they enable the crab to look all around him.
Explanation:
- Crabs have compound eyes, which are made up of thousands of tiny lenses called ommatidia.
- Each ommatidium captures a small portion of the visual field, and the crab's brain combines all the information to create a complete image.
- The small size of the crab's eyes allows them to be positioned all around its body, providing a wide field of vision.
- This enables the crab to detect potential threats or prey from multiple directions, increasing its chances of survival.
- Therefore, statement 1 is correct.
Statement 2: Butterflies have large eyes that seem to be made up of thousands of little eyes.
Explanation:
- Butterflies also have compound eyes composed of numerous ommatidia.
- These ommatidia work together to provide a wide field of vision, allowing butterflies to detect movement in their surroundings.
- The large size of their eyes helps them gather more light, which is essential for their visual perception.
- Each ommatidium captures a small portion of the visual field, and the butterfly's brain processes this information to create a composite image.
- Therefore, statement 2 is correct.
Statement 3: The owl has a large cornea and a large pupil to allow more light into its eye.
Explanation:
- Owls are nocturnal birds and have adapted to hunting in low light conditions.
- To maximize light intake, their eyes have a large cornea, which is the transparent front part of the eye that allows light to enter.
- The large pupil of owls also helps in gathering more light. The pupil dilates in low light conditions, allowing more light to reach the retina.
- The retina of owls has a higher number of rod cells, which are specialized for low-light vision.
- These adaptations enable owls to have excellent night vision and hunt effectively in the dark.
- Therefore, statement 3 is correct.
Conclusion:
- All three statements are correct as they accurately describe the eye specializations of different animals.
- Hence, the correct answer is option D) 1, 2, and 3.
