I would be a narwhal!!!! Individual in my own way and proud of it, but I died because people were too careless and didn't realize how important narwhals were :( stupid people made narwhals like me extinct. That how I think im gonna die
I would be a male African Lion living in an American zoo. Don't have to hunt o scavenge for food, don't have to fight other males to establish dominance, don't have to fight other males/females to takeover a Pride/territory, and don't have to fight off younger males to keep my Pride/territory.
I would live decades longer than wild Lions, be able to grow out my mane fully, have my harem of Lionesses for carefree loving, occasionally offered the chance to mate with Lionesses from other zoos--to contribute to the species' survival in captivity, be fed/cleaned/medically checked up por humans, and adored por all the visitors to the zoo. Yup, that'd be the ultimate life.
