Noch nie davon gehört. Ziemlich scary:

„a man who has been installing video equipment at the aquarium for the last several days, popped into our husbandry office and asked if we could possibly identify a “creature” that his friend, who works on an oil rig, caught on tape from an ROV. He described a manta ray like thing with 30ft tentacles!! He wasn’t far off as you can see for your self. It doesn’t get much more alien than this. I just identified it as belonging to the species Magnapinna, or Big Fin squid, though this one is more commonly known as the Long Arm Squid. They get as big as 5 meters! Take special note of the depth! 7828ft.“
