^^ A guy in my class is from Nigeria, his uncle works on an oil rig out in the ocean and he says that the shit that comes out at night is all sorts of fucked up. He was telling me that to go out there and work on the rig you have to sign a contract saying you won't tell people what you see and that they don't allow cameras or cell phones whatsoever out there.
I don't think he's shitting me either. When you think that only 10% of the ocean floor has been mapped.
I think its because some of the stuff is "scary" looking and they don't want it to scare off tourists.
The contract he signed only stopped him from revealing company information. It had nothing to do with creatures..
