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.
becoz there not in water. they need water to survive
It needs help to swim underwater, else it wouldn't survive! They need to be able to swim without sinking to the bottom of the ocean and just swim around it needs to be able to swim anywhere.
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
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.
Blue whales are ocean dwelling mammals, they need the water to support their body weight, and for their food. The possibility of blue whales going into Mt Everest is 0.
