Some marine biologists do work with some fascinating marine animals called charismatic megafauna including dolphins, whales, turtles, and sharks.
While these specialists dedicate their work to studying and protecting these animals, they would be the first to tell you; incautiously jumping in the water for a swim is not only a danger to the animals but also to you. Obviously, swimming with marine life in captivity is not an option and should not be supported.
So, weekend cuddles with dolphins are not usually on the agenda.
And still, marine biologists will have fascinating encounters with marine life. Maybe you encounter the curious turtle on a dive or witnessing the wonder of mass coral egg release (called spawning); the things you can see will leave you breathless. For those that like something more exciting, like me, shark encounters are unforgettable moments.
Besides, the work of a marine biologist spans beyond that what your eyes can see. From plankton to bacteria all the way down to individual cells and DNA; the work of a marine biologist knows no bounds. The animals that call our oceans home are so diverse and specialized that we have much to learn about them and from them!
