What is a dogfish shark habitat like?
a shark adapt to its environment by lots of different waysbirth...it can only breath under waterit cant stop swimming or it will droundeating other fishby growing its gillsthey can swim from birth...
How do fish gills separate oxygen from water?
When we go underwater, we have to fill our lungs with air in order to stay under the water. Whales and dolphins also have lungs and also have to resurface in order to spend any length of time under the water. Fish on the other hand don't have lungs and very rarely rise to the top of the water, so just how do they survive? As you probably already know, fish have gills. The water around the fish produces a tiny amount of oxygen. In order for the fish to be able to stay under the water he needs to be able to take in oxygen. The fish's gills do just this. They filter the oxygen in the water and this enables the fish to be able to breathe in water. If you take a fish out of the water, it will die of suffocation. This is because the oxygen in the air has not been filtered through its gills and the fish can't breathe it in properly. When you find your goldfish lying dead on the top of its bowl, it has probably suffocated from a lack of oxygen because they oxygen has been used up by some other means such as bacteria. So always make sure you clean Jaws' bowl out regularly!
What does adapted means?
Most things adapt to their surroundings. For example if you went to a new school at first you wouldn't know where to go, for your lessons, to go to the loo, but as you stay at that school you would get to know it a bit better. You !would know where to go, that means that you have adapted to you surroundings. Lots of Animals adapt too, like a Polar Bear is adapted to ice and snow, a fish adapted to water.
What can migration cause?
Migration can be caused by religion or economic opportunity.
How much food does a lynx eat in one day?
lots and lots and lots.......... yepp more like 10 pounds
How alveoli adapted to their jobs?
adapted by having a big surface area so it can absorb more oxygen and it contains lots of oxygen. Also it has very thin tubes for diffusion.
Why do fish gills contains lots of blood vessels?
Fish gills are the equivalent of human lungs. Our lungs, and the fish's gills, are the part of the body that absorb the oxygen we need and expel the carbon dioxide that we nave to get rid of. The way that this happens is through the blood vessels (arteries carry oxygen-rich blood around the body, while veins carry deoxygenated blood) Humans extract oxygen from the air that they breathe into their lungs, while fish obtain their oxygen from the water that passes through their gills.
How do antarctican animals adapt to the climate?
They donr have to they are already adapted by having layers of fat and fur and lots of them have black skin to help absorb heat
Why are gills important to mushroom?
The same as role as lungs, to get oxygen. Only because there is little oxygen in the water the gills have lots of filinents with blood in counter-flow to the water such to maximise surface area and maintain a constant diffusion gradient for the best possible efficiency.
Is their an oxygen in the oceans?
Lots of it. Fish pull it out through their gills. Also in lakes and rivers, too.Of course!! How else do you think the animals (like dolphins) breath??

How do cotton balls soak up oil?
Yes, it does absorb oil but not as well as a sponge or hair. If you need to absorb oil with cotton balls you will need to get lots and lots of them.
Do fish ever get thirsty?
Only if you think they do! Yes. Fish that live in saltwater lose moisture from their bodies through osmosis. These fish need to drink lots of water, or they'll become dehydrated. The extra salt is then simply excreted.
How are salmons adapted to swimming long distances?
It is thin and has lots of fins to swim
Would the fast flowing mountain stream take up oxygen most quickly?
Compared to what? Typically, water at the surface that makes contact with the air would absorb the most oxygen, while water below it would absorb less. Since a fast-moving stream would have lots of turbulence, then it have the water below the surface getting a good chance to change places with the water at the surface ofter, so there would be more water getting to the surface and absorbing oxygen. Also, the fast-moving stream would probably have more air bubbles created, and these bubbles would be in contact with water below the surface and help that water to absorb oxygen stored in the bubble.
How are penguins adapted to live in such a climate?
they huddle up in groups and they have lots of blubber around them
