Swim-with-dolphins

Humans have always been fascinated by dolphins and there has been a long history of association between the two. 1.. The “swim-with-dolphins” tourist industry is becoming more popular every year. The chance to see dolphins in the wild is often a lifetime dream for many people and tour operators are always on the lookout to give their tourist swimmers the best experience they can. After all, it can cost a large amount of money to have this kind of holiday experience. 2.

Research has shown that while dolphins can move away if they do not want to interact with human swimmers , they do not like it at all if the swimmers slip into the water directly on top of them or if humans are in their path of travel. However, if swimmers enter the water to one side of them, the dolphins do not avoid the swimmers to the same extent. 3.
