They're talking about the docufiction film 'Mermaids: The Body Found'.
It's like half documentary half CGI and a lot of renactments.
If any of you havent seen it , I recommend watching it if you find the time.
It honestly blew me away and half of me wants to believe it.
"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."
