Whales' tails move up and down when they swim, just like peoples' legs.
yes yes
false. Fish move their tails side to side to aid motion. However, whales were once land animals and their spines are built differently. To be able to move with that physical set up, their tails move up and down.
yes they do
Yes, Tuna - as all fish and sharks do - move their tails side to side when swimming. Whales and dolphins however, move their flukes up and down.
Whales swim using their fins and tails.
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.
Up and down. I've also noticed that mammals, such as whales and dolphins, beat their tail up and down, while fish, like sharks, beat their tail side to side. Hope this helps!
Side to side
Whales are not fish. Fish move their bodies sideways when they swim; whales move their bodies up and down.
Yes Whales do use their fins to swim so they can turn their bodies by tilting the fin backwards or Forwards.. Same Principal as Fins on Planes! +++ That answers how they steer but they swim primarily by waving their tails up and down.
They use their tails to propel themselves backwards.
So they can swim because they can't move on land.
