Whales need the water. In the the water, whales are weightless. On land, whales weigh tons. If a whale is on land too long, they are crushed by their own weight. beached whales need water poured over them because they live in the ocean, so they are always wet, but when beached, their skin will start to dry out, which can kill them
No, whales cannot live on the shore for an extended period. Whales like Dolphins need for their skin to be wet all the time, also in water they are basicly weightless and their physiology is such that when out of water for extended periods of time they become very tired from just the incredible effort it takes just to expand and contract their lungs. The above posters are correct, but I would like to add that whales need the buoyancy of water and if beached their own weight will kill them.
No. Lakes are fresh water. Whales need salt water.
Well, friend, upthrust is what helps our gentle whale friends stay afloat effortlessly in the vast ocean. When a whale is beached, it loses this upthrust and its weight presses down on its organs, making it hard for them to breathe and survive. It's a sad situation, but with gentle care and help from kind humans, we can guide these magnificent creatures back to safety in the ocean where they belong.
becoz there not in water. they need water to survive
You need to specify where and when if you want to make it possible to answer your question.
we do not need whales at all we do not need whales at all
because the japanese need something to eat
i think killer whales cant live in fresh water because the need to eat and all of the big fish are in salt water
Whales need to breathe air because they are mammals, like humans, and require oxygen to survive. Even though they live in water, they have lungs and need to come to the surface to breathe.
No, they do not need there gills because they have air tubes which are connected to their lungs.
killer whales surley need water if they want to live. if not their skin would dry out and they would die. and if you mean to drink, all there prey contains moisture and they just use that instead of water
Whales use sonar. Also note that not all whales need to locate prey. The largest whales are filter feeders; they just filter out whatever is in the water that surrounds them, and eat it. There is nothing to locate. But sperm whales (for example) do hunt for their prey.
