A lot. Dolphins are aquatic mammals and angel fish are, well, fish. There's a number of contrasts in size, colouring, shape, diet and oxygen source, too.
Why Does Dolphins Jump Out of the Water?
It is not known for certain, but there are many theories. Large whales, like humpbacks, orcas, sperm whales and even young blue whales, as well as many types of dolphins certainly seem to be very playful.
It could be that the dolphins are just simply doing it for pleasure. It is well known that pods of dolphins will play games with pieces of seaweed as they hunt for food, and that many others - including the spinner - are indeed very acrobatic, so why would the dolphins not do it for that reason?
It could also be to rid themselves of baracles and whale lice. Just like fleas do to cats, barnacles and whale lice do irritate whales. Jumping out of the water may be to try and remove the whale lice, but not many people agree with that. After all, beluga whales are known to rub themselves against the sea bed in the spring to relieve itches.
How many dolphins are in a pod?
Humpbacks in numbers are not called pod. The word researchers use for baleen animals is GROUP. A group can be one or more. Baleen whales, in general, do not travel in large groups like toothed cetaceans do. Groups can be up to 8 to 10 when feeding, but it is rare to see groups larger than that, unless in breeding grounds where males compete to gain favor with a female in the area. There we have seen the groups form SUPER GROUPS of more than 15 males!
Why do dolphins live under water?
Evolutionary theory is that dolphins were a land animal which returned to the sea some millions of years ago. They can breathe on the surface because they have a blowhole which allows them to breathe air. They cannot survive for long out of water because their physiology requires that they be suspended in water and because their skin dries out quickly.
Can dolphins defend themselves from sharks?
Dolphins are in actual fact more dangerous than sharks. They have DNA that enables them to defend themselves in the wild, also if a shark comes at them, and all else fails, they can just whip out their air rifles, and shoot the buggers.

Are dolphins smarter than whales?
Determining whether dolphins are smarter than whales is currently impossible due to lack of concrete testing, so it is heavily debated. On one side, it is believed that since whales have larger brains than dolphins that they are automatically smarter. On the other side, some believe that dolphins have an intelligence that is just below that of humans making them smarter than whales.
