A large sign for the Deep Sea World aquarium near the Forth Rail Bridge. There is a steel mesh behind the sign and the sign is located near the entrance to the popular aquarium. Deep Sea World is a very popular aquarium and tourist attraction located on the outskirts of Edinburgh in Scotland. It is located in the village of North Queensferry, in Fife, below another popular monument (the Forth Rail Bridge). The aquarium, like many other aquariums all over the world, has a 112 m long acrylic tunnel that takes visitors under the tank where you can see a large number of water animals, including a number of variety of fish, and even more impressive, the sand tiger sharks, and other variety of sharks. You can even do shark dives even if you are not a qualified diver. And the rays are also incredible, especially as they glide over you on the surface of the transparent acrylic. There are also a number of exhibits that are educational and are helpful to children who are visiting. The aquarium opened in 1993.
