That is serpent. I have seen that on YT channel when the owner of the server made an event for other players. He flew around in debug mode and spawned multiple serpents for an event. As others were approaching we could see exactly what you saw. Serpents unfolded vertically above the water like an antenna (with their heads down). When they came closer, serpents folded back and dropped in the water.

I'm sorry but I do not think it was that either, this was two next to each other, and I was close enough to see the detail, Im kicking myself for not getting a screenshot
