Dolphins are the best
Been on swim with the dolphins trips in NZ. Was smart enough to bring my own fins, because these operators do not supply them.
It's great fun. Dolphins are very curious and like to play.
We've been snorkelling with Bottlenoses, Hectors and .... Dusky dolphins. These last ones are the greatest.
Make funny noises, act weird and they come anc check you out, we were even invited to play along with them in a game of 'pass-the-seaweed'.
Also been freediving with NZ fur seals. They're OK and will show off, but they're better companions for scuba diving. Somehow that's more exciting to them.
And lastly I tried to buddy up with a grey-tip reefshark on the Great Barrier last january. By the time I reached his -12m he just disappeared with 2 strokes of his tail.
