Answer 1

$\large\frak{\underline{\underline{\red{Required \: answer:-}}}}$

1. Crab: Eyes of a crab are quite small but they enable the crab to look all around.
2. Butterflies: Butterflies have big eyes that consist of thousands of small eyes which allow  them to see in the front and at the back.
3. Night Birds (Eg: Owl) : A night bird (owl) can see very well in the night but not during  the day. The owl has a large cornea and a large pupil to allow more light in its eye. Also,  it has a large number of rods and only a few cones in its retina.
4. Kites and Eagles (Day Birds): These birds can see very well during daytime but have  decreased vision at night. This is because they have a large number of cone cells and a  few rod cells.
