Recently, the marine biology exploration and research group, America’s Ocean Exploration Team, went on an expedition on the seafloor of the Puerto Rico Trench - the deepest trench in the Atlantic Ocean, reaching depths of up to 8,800 meters and extending for over 800 km long.During their exploration, the group discovered a host of alien-like, never-before-seen fish, so unique that most couldn't be categorized into an existing species.
