Spinner Dolphins - the most acrobatic jump

You may have already seen some tricks these skilful athletes are capable of, jumping in and out of the sea as they sail next to your boat. But spinner dolphins can perform more even more astounding acts, such as doing spinning jumps. It may seem like a game, but there are a few theories as to why they do it; some say it's one of the ways to express emotions, while others claim it helps these beautiful animals get rid of parasites. Whichever the case, one can't deny it's a truly amazing sight.
