They breathe through the blow hole on the top of their heads
Whales keep air, and thus oxygen, in their lungs, not in their bellies
from eggs and sharks
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.
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.
all sea mammals including whales surface to breathe in air before diving
killer whales are mammals but they can not live on land beacause they are to big and can not walk with flippers.
Whales are mammals, so yes they breath oxygen into lungs, rather than filter water through gills as fish do.
Abiotic factors (non living) that whales use include oxygen, water, sunlight and vibrations (sound waves).
Whales are in the Mammalia class. This means that they are mammals. They give birth to live young, and they feed their offspring milk. Whales are warm blooded and breath oxygen.
