The joy of discovery: scuba diving enables us to experience the 3/4 of earth that is covered by seas and oceans. It is thrilling to see marine wildlife as it moves freely in the water. Sea turtles are particularly fun. Being reptiles they need to surface to breathe air. That creates a pattern of diving under the surface and periodically going back up which is beautiful to observe. Here we are diving in the clear waters of the Exumas, Bahamas.
