No animal is truly "always lonely" as all species interact for mating, but many are highly solitary, like tigers, snow leopards, sloths, orangutans, polar bears, sharks, and some reptiles/amphibians, preferring isolation and only coming together briefly for breeding or hunting, with some, like the Middle East blind mole rat, being exceptionally reclusive.
