Two former National Oceanic Atmospheric Administration scientists, after investigating mass stranding of whales, claims to have recorded mysterious underwater noises coming from an unknown source. This sound resembled a sound previously recorded in 1997, called the "bloop". They recovered 30% of the remains of an unknown creature from inside a great white shark which was said to possess attributes of the human body. They alleged that the marine creature had hands, not fins, and the hip structure of an upright animal. These findings, along with many others led the team to determine that this unknown animal was very closely related to humans ? a mermaid.
