Unfortunately can't submit real people (and I assume animals) so I'd like to give an honorary mention to the 52-Hertz whale, the world's loneliest whale. 52-Blue is/was an individual whale with an unusual call frequency of 52-Hertz, too high for other whales to hear. 52 has never been seen but is believed to have been a blue whale or a fin whale, or possibly a hybrid.
52-Blue has only ever been during mating seasons, and always alone. It is speculated that they were never able to join a pod or find a mate due to other whales not understanding them. Some believe 52-Blue may have also been deaf.
