Among the recently discovered animals there is a giant jellyfish and a new species of humpbacked dolphin.
Experts say that they have yet to find most of the aquatic species. They report that there are approximately 228,450 known marine species worldwide. Also, the scientists estimate that there could be more than 500,000 to 2 million marine species waiting to be discovered.
Jan Mees, researcher at the World Register of Marine Species, stated that the deep sea has not been explored very thoroughly.
Mees fears that some species could go extinct before even being discovered, which means that the scientists will never know of their existence.
Mees, director of the Flanders Marine Institute in Belgium, said that climate change, pollution and acidification are the main factors that lead to the disappearance of entire species.
In 2014, there have been approximately 1,451 new marine species identified, including the Australian humpback dolphin, a South African species of shrimp called “the stargazing shrimp”, and new species of venomous jellyfish of about 50 cm discovered in Australia.
Among the newly discovered marine species, there are approximately 1,000 types of fish, 122 rays and sharks and a new species of barracuda discovered in the Mediterranean Sea.
At the moment, there are approximately 18,000 of known fish species.
Aside from the newly discovered species, the biologists found that many of the species were actually duplicates.
More than 190,000 species were cut off from the list because they were found to duplicate other already known species.
After removing the duplicates from the list, there are now a total of 228,450 known species. Before, there were almost 419,000.
An example of duplicate species is a sea snail known as the rough periwinkle. The researchers discovered that this particular species of sea snail had a total of 113 descriptions made by biologists who did not know that the creature was first discovered and catalogued back in 1792 by an Italian scientist.
The experts believe that there it could take another 360 years to discover all the creatures that swim in every oceans.
