water?

We have legs so it is harder for us but fish have fins so it is easier for fish.

ReplyDeleteFish have gills, so they can move easily in water and we humans have different type of lungs, so it’s hard to swim under water.

I think that fish swim smoothly in water because of its fins.and it sweeps around the water to swim faster.and fishes have gils to help them breath under water.
ReplyDeleteThe reason why fish can move so easily in water, whereas we can’t be because it’s fins helps it steer and its tail propels through the water. They are perfectly designed and streamlined to be able to move through the water easily.
ReplyDeleteThe reason why fish can swim in water better than we can walk in water is because fish are slimmer than human so the water can brush past them and also buoyancy is effecting this.

The reason why fish swim faster is because they have fins, this helps them to swim faster and more smoothly it is like they can glide in the water. But we have legs and this slows us down a lot. They also have gills and this allows them to breathe underwater a lot unlike our lungs. Fish are also specially designed for living in the water.

DeleteFishes can move better than us as Fish has fins, gills and tail help fish move easily.
ReplyDelete1.as fish have fins which help them swim 2.our feet are big that they can sink to the bottom of the water 3.we are to heavy and 4.we have a different way of swimming 5. we have a different way to breath 6.we were not born to swim7. we didn't swim when we were born
ReplyDeleteFishes have fins so that they can swim,Also they are light so they can float.And Humans are heavy and we have feet.

They use their fins and tails to push forward. Fish wriggle in the water and have slippery smooth surfaces,scales. They have a small front and a shape that helps speed.
ReplyDeleteFish have less resistance and they have fins and it's hard for us because water pushes against the object
ReplyDeleteFishes can move so well because they are streamlined so that’s why the move through water so smoothly
ReplyDeleteFishes have fins and gils so that they can swim as they are light and not heavy so they can float.As for humans there heavy in size and we have feet so the ficition and so we stayon water with gravity
ReplyDeleteIt's very easy for fish and boats to swim in water because of their shape. They can swim or sail easly because they have streamline body shape which helps the fish or boat to float.
ReplyDelete(Fact)the fins help the fish to keep in balance. By Tapaswini.
Fish swim better than us because they have better resistance and they have fins and a tale to swim faster also they have gills so they swim more than us underwater!
ReplyDeleteThe fins help balance and fish have the ideal body structure and shape to move perfectly through the water
