The first camera — blacktip sharks. The second camera — a coral reef.
Blacktip shark are the most valuable tenants of the National Aquarium in Baltimore. However, there are other creatures to look at, such as charming sea turtles, making underwater flights, not hasty but graceful.
And of course, there are many other creatures of the ocean; fish of various colors, sizes and configurations. Sharks appear regularly in the camera sight. If your city does not have a decent aquarium, just look at this webpage periodically and enjoy pleasant views and the relaxing sounds of water.
