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!

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.
They need their tails to swim.

No, they use their tails.
Dolphins relate very friendly to their own kind. If they get mad, dolphins will slap their tails.

Dolphins have an opening toward their tails on the bottom side from which waste is expelled.
no they have fins and tails but no legs or arms :)
Dolphins move with the help of there fins and the move to get there food.
Dolphins have tails to swim, manouvere and to jump, if they didn't have a tail they would drown, Hope that helps! =)
Like many other dolphins Bottlenose use their flukes (tails) and flippers to create vibrations along the sand/mud along the ocean floor and to move it around. Other fish think that a predator is coming and leap out of the water straight into the incoming dolphins mouth
