Whats the strangest animal you can think of?

Praya dubia is a 100 foot siphonophore that lives near the bottom of the ocean. It is transparent, bioluminescent, fairly fragile, and squishy. Each little segment of its body -- of which there are innumerable -- is its own little organism, specialized to operate as part of this continuous body. Oh, and it can barely move on its own, so it sort of just drifts around in ocean currents, hoping a very unlucky little creature meanders into its tentacles. Scientists know little about them, since they can't be taken to the surface without first bursting from lack of pressure.

Also, it's name means, "doubtful prayer," which I think we all can agree is creepy as fuck.
