I have a theory on the bloop noise. what if it was made by a creature i’m going to call the cryotherium (ice beast) this could be a fish-mammal like animal that lives in the cold deep waters of the southern hemisphere what if these creatures live for hundreds of years and return to antarctica to breed. one reason people didn’t believe in the bloop is because the food chain likely couldent sustain such a large organism. i believe it would have a extreamy large mouth for feeding on microfauna or marine snow, along with occasionally hunting large predators. this animal would have extreamly slow metabolism that way it could survive or minimal food in a harsh inviroment maybe it could shut off or make certain parts of its body dormant when not in use ex: the reproductive system. one reason we have never found a carcass is that its young consume it when it reproduces. i believe this would be most closely related to the orca and around 100-150 feed it langth. i also think it would be rather found in shape to conserve heat. any thaught?
