Mysterious Rods...What are they?

[TraineeHuman]

I've read material on the internet in the past from various sources regarding the ETs who look a bit like tadpoles and are quite tiny in size (maybe an inch long). They apparently live in bases at the bottom of the oceans. The rods look the right shape and size to be the same as in other photos I have seen of their spacecraft -- which seem to be very fast and very sophisticated, and based on anti-gravity etc.
