All morning long we have had a very feisty dolphin calf and its mellow mother swimming around the boats in the harbor. At one point they were so close to our swim platform that we could have reached out and touched them.
The baby was 'spy-hopping', jumping out of the water, doing brief speed runs (in the opposite direction of Mom), and swimming upside down.
Meanwhile, Mom slowly swam nearby and occasionally pushed the calf around with her rostrum. Amazingly, they were both even sneaking up on people in their dinghies and we would yell, "Look behind you!" followed by lots of "oohs and ahs". What a fun playground for the dolphins, and great entertainment for us all!
