The video originally questioned in this post has been removed from YouTube. The video below is a replacement and apparently of artistic production. However, contactee Domingos Yezzi affirms that mermaids do indeed exist.
This is not a skeleton of an ET but of an underwater inhabitant, with whom I’ve had contact with and it is written in my fourth book; that is, “male and female” mermaids — if we can call them “male mermaids.” They have underwater communities and have appeared to some travelers of antiquity, [such as] Ulysses, for example. No, it is not a legend. They indeed exist. During the tsunami of Japan one of them was found dead on a beach, nobody took it seriously and was announced that it was an internet joke. That might have been the case, however, I assure you that they do exist; and they usually sing on large rocks or islets in the middle of the ocean. There is a proof. Please translate this for the readers of this page, okay?
