A team of deep-sea researchers discovered a mysterious flesh-like gold orb at the bottom of the ocean — one so alien-like it felt like “the beginning of a horror movie.” ...

The leading theories are that the gold orb is an egg case of a potentially unknown species, or that it's a type of sponge. "I'm Team Egg Case at the moment, but I'm excited to find out," Candino said.

The orb, which weighs a staggering 1.3kg, usually sits in the Tower of London as part of the Coronation Regalia and has played a central part of the crowning of monarchs for hundreds of years.
