My buddy and his wife recently went on a cruise to the Caribbean. They had a wonderful time and took lots of beautiful pictures. One of the things they did was go snorkeling. It looked like a lot of fun. They actually wore wetsuits and had an underwater camera they used to take lots of pictures of small fish around a coral reef. They said it was a little cool and that was one reason they decided to wear the wetsuit. The water was so clear anyway but being able to snorkel and have your head underwater they were truly able to experience the beauty of that coral reef ecosystem. They took pictures of fish, octopuses, and what looked like the remains of some small sunken ship. If I ever go on a cruise to that area of the world, I definitely think that snorkeling is one activity I want to try.
