Where did you get cuttlefish eggs?
I don't think the video is a cuttlefish. especially if it is moving that fast tentacles first. Can you see the appendages clearly enough to determine they are, in fact, tentacles and not mandibles or maxillae.? To my knowledge cuttlefish don't chase prey like that, they are sneaky and shoot out their tentacles while standing stock still. Of course their behavior could be different in the larval stage.
