It is here that we get to the bizarre thing about the Eltanin Antenna. In spite of scientific views doing anything but leaning this way, numerous individuals took the object as alien in origin. Thing with sharp angles at the bottom of the ocean? Aliens. To this day, UFOlogists and other hokey-pokey hobbyists think this device is either extraterrestrial or part of some conspiracy. Too bad reality is nowhere near as interesting.
As few as 7 years before the picture of the Eltanin Antenna was taken (possibly fewer), it was identified as a type of carnivorous sponge by the name of Cladorhiza concrescens. Sure, it is carnivorous, oddly shaped and living in a pretty unforgiving environment, but it is certainly terrestrial as much as anything else that exists on Earth is. Of course, the identification is called into question by die hards, but if you look at the Bulletin of the Museum of Comparative Zoology, Volume 15, you will see that Fig. 541 looks very much like the Eltanin Antenna and this figure was published in 1888.
