Want this question answered?
Dolphins move up and down. Fish move mostly in a straight line.
they usually eat insects, fish, frogs ans small water birds
It is just as good as a human that are not blind
Yes but if your talking about human attacks it's not that the shark wants to attack a human. It's a feeding instinct, when we're in the water we move like any creatures a shark preys on such as birds and smaller fish, they don't know it's a human in the water
Okay, I'm guessing the questioner is young. Mammals are covered with skin and hair, fish are covered with small scales, and birds have skin and feathers. Mammals have live births, whereas fish and birds lay eggs. Mammals and birds are warm blooded and can regulate their own body temperature, whereas fish are cold blooded and regulate to the water around them. Mammals and fish have teeth; birds do not. Birds can fly because their bones are hollow to help them move through the air; fish have gills to help them breathe underwater and mammals are basically land animals, with the exceptions of the whale and dolphin.
their fins and other physical features are thinned, unlike humans. Humans, in comparison to fish, have much bulkier limbs than fish. Water is able to move/glide past the fish body parts easier.
I wouldn't. If the nest is moved, and with human scent on it, the mother bird will usually abandon it. Leave it be until the baby birds are kicked out to fly on their own. Then it can be removed.
Not only can they behave differently, they can look different too. Some fish will move more slowly, some fish may appear to be "resting" more often. Some fish colors become more vivid with age, some fade with age. Some loose their markings with age, and others develop other markings as they age. So it's not really easy to answer that question when talking about all fish. When talking about a specific fish it's easier to answer.
They both help a fish to move
pushs the fish to move
There are many online sites that have worksheets on how animals move differently. You can find them at home school websites and some teacher blogs.
when a cowboy used a shotgun too kill a flock of birds at close range, he said "like shooting fish in a barrel" most likely, because shooting fish that can't move much anywhere can be shot easier then fish in the ocean.
