For what purposes do animals use the following? i) webbed feet
ii) sharp claws
iii) strong eyesight
iv) gills
v) wings

I) webbed Feet are useful for pushing animals quickly through water, especially for animals who swim often but still maintain legs / limbs that aren’t fish… more effective than other feet or limbs but still more mobile in other terrains unlike fish
ii) Sharp claws are often used either to hunt and kill or disable prey, or as self defense; sometimes both. Predators use them to capture prey within their grasp and sometimes kill prey. Prey animals will use them as defense.
iii) strong eyesight is useful for animals which require food sources that are camouflaged: eyesight is also useful for animals who rely on body-language as communication with one another, as well as animals like humans who interpret things like sign language. Strong eyesight during different times of day are useful for animals depending on what time they are awake and actively searching for food. Eyesight can also help animals avoid different dangerous situations, such as spotting predators from afar, etc.
iv) gills are used to allow animals to breathe underwater. This is useful for creatures who live beneath the water, hunt underwater / have food sources mainly underwater, or who otherwise spend long times hiding under the ocean or even living in secure places in water.
v) wings allow animals to glide or take flight; they’re initially useful for allowing animals a useful mode of transportation for escaping from predators, building / living in more secure places where other animals cannot go, hunting (such as hawks hunting mice from the air), and more. It also allows for easy and powerfully reliant migration.

None of these answers were taken from a text, they were just off the top of my head. Hope this helps :)
