Whales keep air, and thus oxygen, in their lungs, not in their bellies
they sleep on there bellies to keep very warm
from eggs and sharks
beluga whales keep their bodies moving by eating and sleeping
bellies
no it does not if you keep your distance and do not disturb the whales.
They cant keep Whales in captivity but if your talking about Killer Whales and other Whales like Balugas then yes they do.
Whales store air In their lungs and oxygen in their blood. Humans do the same thing, but we're not as good at as whales.
For threm to breathe and get oxygen.
Fish use gills, which extracts oxygen from the water. Amphibians and whales breath oxygen, whales can hold their breath for hours at a time, explaining how sperm whales can hunt at great depths for periods of time.
If we humans keep hunting and killing the whales then they will be come extinct.
Sharks have gills to extract oxygen whereas whales , being mammals , have lungs from which they get their oxygen . Whales need to surface in order to access oxygen while a shark is not burdened with this necessity thus being able to stay underwater indefinitely .
Whales are mammals that breathe air and fish draw oxygen from the water. whales have live birth instead of eggs and parent there offspring. whales have skin not scales. whales also have special long teeth which you only see in bottom feeder fish. And fish have vertical tails that they move side to side to swim, whales have horizontal tails that they move up and down to swim. Whales have to take in oxygen cuz they are mammels and fish take oxygen from the water through gills also whales can use echo location.
