Here are the strangest things found in the ocean! Check out these awesome underwater treasures and other mysterious deep sea discoveries!

9. An Ancient Computer Recovered in the early 1900s by Greek divers, the Antikythera mechanism was found inside a Roman shipwreck near the Greek island of the same name. It is believed to the earliest form of a computer that is at least 2,000 years old. This complex clock-like device was used by ancient Greeks to calculate the movement of the stars and planets. The mechanism was composed of at least 30 different bronze gears and the whole thing was housed in a wooden frame that was decorated with thousands of characters. As so much of this period of history's technology has been lost, such advanced use of technology did not reappear in European historical artifacts until the 14th Century. It is now on display at the National Archaeological Museum of Athens. The history of this device is shrouded in mystery. It is unclear how this intricate device ended up in the hands of Romans, but some believe the ill-fated ship was transferring a woman of importance to be married in Rome. The mechanism, among other impressive riches on board, may have been a wedding gift from her family.

8. Baltic Sea Anomaly The Baltic Sea Anomaly was accidently discovered by a team of diving experts and treasure hunters from the Ocean X Team in 2011. The divers found a circular object with a diameter of about 160 feet that appeared in a sonar image as it sat on the sea bottom. It looks like the “Millennium Falcon” from “Star Wars”, and has an architectural structure similar to Stonehenge in Britain. Oddly enough, all of the divers’ electrical equipment stopped functioning within 650 feet of the entity and it emits a strong radio signal. Some say it could be a pre-Ice Age artifact or a German anti-submarine device. A long track seems to lead towards the thing which makes people think it is some kind of landing strip. The Swedes finally managed to organize an expedition finally in 2012. The very first shots of the object at close range showed that it is unlikely it had ever flown. It seems that it is not a “flying saucer”, but rather a kind of construction. The most probable theory was provided by Volker Bryuherta from Stockholm University. According to him, it’s just a rock. Since the Baltic Sea came under the influence of melting glaciers, these rocks probably formed at the same time. But this does not explain why satellite phones and cameras stop working near this “rock”. Though various scientists have offered innumerable suggestions about the entity’s origins, the Baltic Sea anomaly still remains one of the unsolved intrigues and ocean mysteries of the world.

7. The Bimini Road The Bimini Road, sometimes called the Bimini Wall, is an underwater rock formation near North Bimini island in the Bahamas. Researchers, geologists, archaeologists, and scientists alike have visited and studied the huge, flat stones off the coast of Bimini, known as the Bimini Road . They have tried for years to discern whether the limestone blocks are a natural phenomenon, or evidence of an ancient lost civilization. About 20 feet down in the clear blue water, is a stone path. Most people think it's a road made up of limestone blocks that's about half a mile long, but no one knows where it goes or what its purpose might have been. The stone blocks are huge and some are about 13 feet long. An American expedition in 2004 discovered a second and third layer of stone blocks which also suggests a wall of some sort although they weren't able to get to the bottom. Some people think that this might be proof of the location for the lost city of Atlantis.

6. Emeralds Amateur diver and treasure hunter Jay Miscovish walked into a bar in Key West and bought a treasure map from a diver friend at a bar in 2010. He went on to discover more than 10,000 emeralds off the coast of Florida, making it one of the largest discoveries of sunken treasure in history. His company claimed that they had found over 154 pounds of emeralds, amethysts, and other stones lying on the ocean floor. Journalists from CBS news when to interview him and he poured out a laundry basked full of emeralds and told them that they likely came from an ancient shipwreck. The story earned him mass media attention but he refused to give out more information about the map and the man who had sold it to him, claiming he had paid him $50,000 to give up all rights to the treasure. Camera crews went with him on a dive and they also found emeralds and amethysts lying on the ocean floor but no hint as to the actual vessel that may have been transporting them.
